Anonymous methods provide a technique to pass a code block as a delegate parameter. Anonymous methods are the methods without a name, just the body.
Let us see how to declare Anonymous methods in C# −
delegate void NumberChanger(int n); ... NumberChanger nc = delegate(int x) { Console.WriteLine("Anonymous Method: {0}", x); };
The following is an example to implement Anonymous methods in C#.
using System; delegate void NumberChanger(int n); namespace DelegateAppl { class Demo { static int num = 10; public static void AddNum(int p) { num += p; Console.WriteLine("Named Method: {0}", num); } public static void MultNum(int q) { num *= q; Console.WriteLine("Named Method: {0}", num); } public static int getNum() { return num; } static void Main(string[] args) { //create delegate instances using anonymous method NumberChanger nc = delegate(int x) { Console.WriteLine("Anonymous Method: {0}", x); }; //calling the delegate using the anonymous method nc(10); //instantiating the delegate using the named methods nc = new NumberChanger(AddNum); //calling the delegate using the named methods nc(5); //instantiating the delegate using another named methods nc = new NumberChanger(MultNum); //calling the delegate using the named methods nc(2); Console.ReadKey(); } } }
