How to Send Large File From Client To Server Using WCF?

Question

How to Send Large File From Client To Server Using WCF in C#? Below the configuration code.

Answer 1

You need to check out streaming, as Dzmitry already pointed out.

In order to be able to send large files as a stream to your service, you'll need to:

• create a service method that accepts a Stream as its input parameter
• create a binding configuration (on both the server and the client) which uses transferMode=StreamedRequest
• create a stream in your client and send it to the service method

So first off, you need a method in your service contract:

[ServiceContract]
interface IYourFileService
{
   [OperationContract]
   void UploadFile(Stream file)
}

Then you need a binding configuration:

and a service endpoint on your service using that binding configuration:

and then, in your client, you need to open e.g. a filestream and send that to the service method without closing it.

Hope that helps!
