The simplest sample to understand Anonymous Functions

Read the comment in between the code.

using System;




  delegate void TestDelegate(string s);

  static void M(string s)





  staticvoid Main(string[] args)


    // Original delegate syntax required

    // initialization with a named method.

    TestDelegate testDelA = newTestDelegate(M);


    // C# 2.0: A delegate can be initialized with

    // inline code, called an “anonymous method.” This

    // method takes a string as an input parameter.

    TestDelegate testDelB = delegate(string s) { Console.WriteLine(s); };


    // C# 3.0. A delegate can be initialized with

    // a lambda expression. The lambda also takes a string

    // as an input parameter (x). The type of x is inferred by the compiler.

    TestDelegate testDelC = (x) => { Console.WriteLine(x); };


    // Invoke the delegates.

    testDelA(“Hello. My name is M and I write lines.”);

    testDelB(“That’s nothing. I’m anonymous and “);

    testDelC(“I’m a famous author.”);


    // Keep console window open in debug mode.

    Console.WriteLine(“Press any key to exit.”);
