Hi Jegan Priya, http://www.c-sharpcorner.com/Blogs/14543/how-to-handle-delegate-and-multicast-delegates.aspx public class MethodClass { public void Method1( string message) { System. Console .WriteLine( "Method1 " + message); } public void Method2( string message) { System. Console .WriteLine( "Method2 " + message); } } class Program { public delegate void Del ( string message); static void Main( string [] args) { Del handler = DelegateMethod; Console .WriteLine( "calling a delegate method from current class" ); // Call the delegate. handler( "Hello World" ); Console .ReadLine(); MethodClass obj = new MethodClass (); Del d1 = obj.Method1; Del d2 = obj.Method2; Del d3 = DelegateMethod; Del allMethodsDelegate = d1 + d2; Console .WriteLine( "calling a combined delegate method from other class" ); allMethodsDelegate( "Hello World" ); allMethodsDelegate += d3; Console .ReadLine(); Console .WriteLine( "calling a combined delegate method from other class and current class" ); allMethodsDelegate( "Hello World" ); Console .ReadLine(); int invocationCount = allMethodsDelegate.GetInvocationList().GetLength(0); Console .WriteLine( "Getting total count invocation list form a delegate, for the last one " + invocationCount.ToString() + " items (two form other class and one from current class " ); Console .ReadLine(); } public static void DelegateMethod( string message) { Console .WriteLine(message); } public void MethodWithCallback( int param1, int param2, Del callback) { callback( "The number is: " + (param1 + param2).ToString()); } } Regards, Selva Ganapathy K

Try this: using System; class Test { static void Main() { (new Action(Method1) + new Action(Method2))(); Console.ReadKey(); } static void Method1() { Console.WriteLine("Hello from Method1"); } static void Method2() { Console.WriteLine("Goodbye from Method2"); } }
