Email a RDLC Report in Asp.Net MVC

I made a simple application in Asp.Net MVC in Visual Studio 2015.

The application has 2 models, Orders and OrderDetails.

I've also made a Report1.rdlc file with the DataSet from Orders.

I've searched a lot about RDLC Reports but i don't understand how it really works.

I want to send an email (pdf) with the report to everyone who made an order.

Can somebody explain how it really works and what the best is that i can do?

Has someone a simple explanation or example?

Thanks in advance!
