Invoking a delegate asynchronously

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

hope this help.

The C# allows to call the delegates asynchronously.

The BeginInvoke and EndIvoke methods are used.
