basic Authentication in .net framework 2.0

2021-02-21 19:23 Kimetsu imported from Stackoverflow

I need help in asp .net, I want to read the username from the HTTP header in .net framework 2.0. (like we do in basic authentication) Is there a way to do that? Thanks in advance.

P.S: I know it's old but need to do it.

Filter items in a listbox that have been added with json

Well I'm trying to list items that are from listbox created with UserControl and the text properties are defined with a json file.

This is my .json file:

{
    "Games": {
        "Quantity": 2,

        "Title0": "SomeGame1",
        "Description0": "Fps game",
        "Image0": "Some image link",
        "Link0": "GameStore.com/Somegame1",

        "Title1": "SomeGame2",
        "Description1": "RPG game",
        "Image1": "Some image link",
        "Link1": "GameStore.com/Somegame2",
    }
}

This is the code to load the games as items in the listbox:

string JsonFile =  Environment.CurrentDirectory @"\Test.json";
dynamic jasonfile = JsonConvert.DeserializeObject(JsonFile);

GameUserControl[] Games = new GameUserControl[jasonfile["Games"]["Quantidade"]];

for (int quantity= 0; quantity < Games.Length; quantity++)
{
    Games[quantity] = new GameUserControl();

    Games[quantity].Descrição.Content = (jasonfile["Games"]["Title" + quantity]);
    Games[quantity].jog = (jasonfile["Games"]["Titulo" + quantity]);
    Games[quantity].lin = (jasonfile["Games"]["Link" + quantity]);
    string image = jasonfile["Games"]["Image" + quantity];
    Games[quantity].imag = new ImageBrush(new BitmapImage(new Uri(image, UriKind.Absolute)));
               
    GamesListBox.Items.Add(Games[quantity]);
}

This is the code I used in a textbox to try to filter:

 if (CollectionViewSource.GetDefaultView(GamesListBox.Items) != null)
                    CollectionViewSource.GetDefaultView(GamesListBox.Items).Filter = (o) => { return o.ToString().ToLower().Contains(Search.Text.ToLower()); };

But it didn't work, the item names are always GameUserContro.Can someone help me?

Advantage of .Net Core over WCF for RESTful APIs

We are currently using WCF to create RESTful APIs, it is working fine and has an added advantage that it can be consumed via SOAP too if we ever need to. We have all our systems using Microsoft technologies.

There is no active development on WCF but the current functionality is working fine for us. However, I believe the recommended approach is to start using .Net core for RESTful services. What are the additional advantages .Net core offers over WCF (apart from being platform independent)?
Generic class type constraint with a generic class having another constraint
Let's say I have a generic class
```
public class G<T> {
}
```
and I want to declare final class as
```
public class F<T> where T : G<T> {
}
```
that seems to be possible, but what if I want to complicate the task and add a constraint to the class G like that
```
public class A {
}

public class DA : A {
}

public class DB : A {
}

public class G<T> where T : A {
}
```
and finally I want to do this
```
public class F<T> where T : G<T> {
}
```
that does not work, it says T has to be of type A which is understandable and it looks like I can rewrite it like this
```
public class F<T, U> where T : G<U> where U : A {
}
```
but in this case the usage has a redundant declaration
```
public class DF : F<G<DA>, DA> {
}
```
I have to repeat DA twice when using class F even though it is quite clear if I use G as a generic type the generic type of G is DA. Is there a way to avoid this redundancy?

Cascading databound <ajaxtoolkit:combobox> and <asp:dropdownlist> in asp.net

I have an asp.net search form that includes an ajaxToolkit Combobox and a standard asp DropDownList. Both controls are bound to two separated SqlDatasource components.

Something like this:

<ajaxToolkit:ComboBox
    ID="cbConvenzionato"
    runat="server"
    AutoCompleteMode="SuggestAppend"
    DropDownStyle="DropDownList"
    DataSourceID="sdsConvenzionati"
    DataTextField="nome"
    DataValueField="id"
    AutoPostBack="true"
    OnSelectedIndexChanged="cbConvenzionato_SelectedIndexChanged" />

<asp:DropDownList
    ID="ddlVeicoli"
    DataSourceID="sdsVeicoli"
    DataTextField="targa"
    DataValueField="id"
    runat="server"
    AutoPostBack="true"
    OnSelectedIndexChanged="ddlVeicoli_SelectedIndexChanged"
    AppendDataBoundItems="true">
    <asp:ListItem Text="TUTTI" Value="" Selected="True" />
</asp:DropDownList>

<asp:SqlDataSource
    ID="sdsConvenzionati"
    runat="server"
    ConnectionString="<%$ ConnectionStrings:db %>"
    ProviderName="<%$ ConnectionStrings:db.ProviderName %>"
    SelectCommand="
        SELECT
            id,
            nome
        FROM
            anag_convenzionati
        ORDER BY nome;" />

<asp:SqlDataSource
    ID="sdsVeicoli"
    runat="server"
    EnableCaching="false"
    CancelSelectOnNullParameter="false"
    ConnectionString="<%$ ConnectionStrings:db %>"
    ProviderName="<%$ ConnectionStrings:db.ProviderName %>"
    SelectCommand="
        SELECT 
            id, 
            targa
        FROM 
            veicoli_contratti
        WHERE
            ((@id_convenzionato IS NULL) OR (id_convenzionato = @id_convenzionato))
        ORDER BY targa;">
    <SelectParameters>
        <asp:ControlParameter
            Name="id_convenzionato"
            ControlID="cbConvenzionato"
            PropertyName="SelectedValue"
            Direction="Input"
            ConvertEmptyStringToNull="true"
            DbType="Int32"
            DefaultValue="" />
    </SelectParameters>
</asp:SqlDataSource>

There's also a third sqldatasource (sdsNoleggi) that feeds a gridview but this's not a problem right now.

In code behind I have two event handlers:

    protected void cbConvenzionato_SelectedIndexChanged(object sender, EventArgs e)
    {
        sdsVeicoli.Select(DataSourceSelectArguments.Empty);

        Search();
    }

    protected void ddlVeicoli_SelectedIndexChanged(object sender, EventArgs e)
    {
        Search();
    }

    private void Search()
    {
        sdsNoleggi.Select(DataSourceSelectArguments.Empty);
    }

I tought in this way I should filter ddlVeicoli items after selecting an item in cbConvenzionato... but it's not working... why?

If I look into sdsVeicoli SelectParameters in debug I can see id_convenzionato being correctly set to selected value (id coming from cbConvenzionato) I bet also that sdsNoleggi dataset wiil be correctly updated with new values since I did this many times before. So why bound control it's not? I tried also to force a ddlVeicoli.DataBind() after sdsVeicoli.Select() call ... but this had no effect.

Swagger UI not working for REST API (asp.net web api2) application

I have asp.net mvc project with .NET Framework 4.7.2 and the same project contains asp.net web api2 controller in a separate folder : Controllers. The solution is legacy. The API are already in use in the PRODUCTION environment. Now I added the Swagger nuget package (Install-Package Swashbuckle -Version 5.6.0) to this existing project. Post that I see a SwaggerConfig.cs added to the App_Start folder of the Solution Explorer.

Here the asp.net mvc controllers are used by App1 pointing to the server: www.app1.com and asp.net web api2 controllers are used by another frontend angular app: App2 pointing to the server : www.app2.com

The complete deployment package for both App1 and App2 are hosted in IIS

Any request related to App1 is handled by www.app1.com and any api request related to App2 (Angular frontend) is handled by App1 only using IIS Rewrite rules at App2 level which redirect any api request to App1 only.

Now in this case when I tried to navigate to www.app1.com/swagger , I see it is loading the SwaggerUI for me, but when I tried to navigate to www.app2.com/swagger it is not working and instead of that it is loading the Angular frontend application

Here goes the App1 and App2 at IIS level:

Can anyone help me here by providing their guidance to fix this issue?

Cors error missing allow origin header. MailKit

I have cors error missing allow origin header error only on ONE post request. My CORS Policy

public void ConfigureServices(IServiceCollection services)
        {
            services.AddCors(options =>
            {
                options.AddPolicy("AllowAllOrigins",
                      builder =>
                      {
                          builder.SetIsOriginAllowed(_ => true)
                                  .AllowAnyHeader()
                                  .AllowAnyMethod()
                                  .AllowCredentials();
                      });
            });
}

Every request work fine, but one POST request fails, it's really weird. Code in controller action which failed use MailKit and SMTP to send email, maybe that's cause

Web API - Need a way to return Multipart Form data in response

I am currently building a web service to replace one of the legacy application and the web service response has to be matching to the existing service. I am currently using .Net 5.0 Core ASP.Net web API.

The request format for the service is

/DocuemntService?info&pVersion=0046&contRep=Z8&docId=%7BDCC15450-79FE-45BF-AC73-250544C8F8EE%7D&accessMode=r

Response Expected : This was the raw output captured from legacy service (Note this only returns document info in headers and not the document)

So far I used the following code from Controller to return the multipart form data, but it pushes json file and it doesnt return anything similar to above.

[ProducesResponseType(StatusCodes.Status200OK)]
        [ProducesResponseType(StatusCodes.Status400BadRequest)]

        public async Task<HttpResponseMessage> DocumentServer([FromQuery] DocumentInfoRequest requestInfo)
        {
            HttpResponseMessage ApiResponse= new HttpResponseMessage(HttpStatusCode.OK);
            IQueryCollection queryStringParams = ControllerContext.HttpContext.Request.Query;
            Response.ContentType=
            if (Request.Query.Keys.Count > 0)
            {
                //First query parameter determines the operation
                String operation = queryStringParams.Keys.First();
                switch (operation)
                {
                    case "serverInfo":
                        ApiResponse=await ServerInfo2(requestInfo, ApiResponse);                        
                        break;
                    case "info":
                        DocumentInfo doc = DocumentInfo(requestInfo, Response);
                        Response.Headers.Add(AppConstants.XCSINFOS_BEGIN);
                        Response.Headers.Add(AppConstants.DATE);
                        Response.Headers.Add(AppConstants.XCSINFOS_END);                                                
                        using (MultipartFormDataContent multipartForm =   new MultipartFormDataContent("NEXT_COMPONENT"))
                        {
                            multipartForm.Headers.Add("X-docId", requestInfo.DocId);
                            multipartForm.Headers.Add("X-compId", doc.CompId);                            
                            Response.Headers.Add(new KeyValuePair<string, Microsoft.Extensions.Primitives.StringValues>("X-docId", requestInfo.DocId));
                            Response.Headers.Add(new KeyValuePair<string, Microsoft.Extensions.Primitives.StringValues>("X-compId", doc.CompId));
                            await WriteData(Response, "Test");
                            ApiResponse.Content = multipartForm;                                                       
                        };
                        break;
                    case "get":
                        await DownloadDocument(requestInfo, Response);
                        break;
                    case "create":
                        break;
                }
            }
            return ApiResponse;
        }

I am not sure whether I am following the right approach? The above code is only sample to see whether it returns few parameters and if it works my plan is to develop to return all document info and in the Get request, return the document itself.

I primarily have the java background and tried to implement this in Web API because .Net is preferred for this application deployment.

I already wasted quite a lot of time on this and I couldn't find any relevant article to solve this problem.

Any help or direction would be much appreciated?

Thanks
