What are generic delegates in C#?
Using generic delegates, you do not need to define the delegate statement. They are defined in the System namespace.
You can define a generic delegate with type parameters. For example −
delegate T myDelegete<T>(T n);
Example
The following is an example showing how to create generic delegates in C# −
using System; using System.Collections.Generic; delegate T myDelegete<T>(T n); namespace GenericDelegateAppl { class TestDelegate { static int num = 5; public static int AddNum(int p) { num += p; return num; } public static int MultNum(int q) { num *= q; return num; } public static int getNum() { return num; } static void Main(string[] args) { //create delegate instances NumberChanger nc1 = new NumberChanger(AddNum); NumberChanger nc2 = new NumberChanger(MultNum); //calling the methods using the delegate objects nc1(50); Console.WriteLine("Value of Num: {0}", getNum()); nc2(10); Console.WriteLine("Value of Num: {0}", getNum()); Console.ReadKey(); } } }
