Invoking a delegate asynchronously

Question

Hi friends I want to know that which method would be used to invoke a delegate type asynchronously in c#? Give an example with code?

Create a thread and execute the delegate in the thread.

hi Delegates are special types supported by the .NET Framework that represent a strongly typed method signature. Delegates can be instantiated and formed over any target method and instance combination where the method matches the method's signature. C# allows us to create special classes using the delegate keyword. Delegate has two methods named BeginInvoke and EndInvoke . The signatures of these methods are based on the signature of the delegate type. delegate int Add(int x int y) exposes by compiler generation IAsyncResult BeginInvoke(int x int y AsyncCallback callback object object IAsyncResult result); int EndInvoke (IAsyncResult result); Add d = ShowSum; IAsyncResult ar = d.BeginInvoke(10 10 null null); int sum = d.EndInvoke(ar); public int ShowSum( int x int y ) { return x + y; } please refer http://www.codeproject.com/Articles/14931/Asynchronous-Method-Invocation hope this help.

The C# allows to call the delegates asynchronously. The BeginInvoke and EndIvoke methods are used. You can find example in the following urls: http://stuarthallows.wordpress.com/2011/03/07/calling-a-delegate-asynchronously-various-methods/ http://msdn.microsoft.com/en-us/library/h80ttd5f.aspx http://msdn.microsoft.com/en-us/magazine/cc301332.aspx
