  Looking for Implementation of IAsyncResult in C#?

  Dec 30, 2012 12:43 AM|LINK

  I am looking to instantiating AsyncResult object but there seems to be no AsyncResult class  with a constructor in .Net Frameowork that I can instantiarte.

  Can someone provide an implementation of IAsynResult interface in C#?

  there seems to be no AsyncResult class

  Not true; Google finds it easily.  http://lmgtfy.com/?q=AsyncResult

     "AsyncResult Class"  .NET Framework 4.5":
     http://msdn.microsoft.com/en-us/library/system.runtime.remoting.messaging.asyncresult(v=vs.110).aspx

  [ComVisibleAttribute(true)]
  public class AsyncResult : IAsyncResult,
  	IMessageSink

  Versions of AsyncResult have existed since .NET Framework 1.1

  See the remarks at the above link.

  Also, study the example at the above link ... note especially this code:

  // Initiate the asychronous call.
  IAsyncResult result = caller.BeginInvoke(3000, out threadId, null, null);

  see also:  http://msdn.microsoft.com/en-us/library/22t547yb.aspx "Asynchronous Programming Using Delegates"

  Joe Albahari's free e-book "Threading in c#" is well worth reading:  http://www.albahari.com/threading/

  important:  c# 5 has advanced threading:
  http://msdn.microsoft.com/en-ca/library/vstudio/hh191443.aspx
   "Asynchronous Programming with Async and Await" (C# and Visual Basic). Visual Studio 2012

  "Visual Studio 2012 introduces a simplified approach, async programming,
   that leverages asynchronous support in the .NET Framework 4.5 and
   the Windows Runtime. The compiler does the difficult work
   that the developer used to do, and your application retains a logical structure
   that resembles synchronous code. As a result, you get all the advantages
   of asynchronous programming with a fraction of the effort."
