Delegates in C#

 
Delegates are nothing but it is a reference to the methods and Delegate is a keyword used to create a method object and it will help us to pass the method as parameters.
 
Declarations
  1. public delegate TypeOfDelegate Delegate_Name();  
Examples
  1. public delegate string myDelegate(string FirstName, string LastName);  
I would like to share the Type of Delegates in C# and please refer the details below,
  • Single Delegate
  • Multicast Delegate
  • Generic Delegate
Sample Programs
  1. public delegate string myDelegate(string FirstName, string LastName);  
  2. public class Personal {  
  3.     public static string myDelegate(string FirstName, string LastName) {  
  4.         return FirstName + "" + LastName + "";  
  5.     }  
  6.     static void Main(string[] args) {  
  7.         string FirstName = "Manikandan";  
  8.         string LastName = "M";  
  9.         //Creating the Delegate object  
  10.         myDelegate delObj = new myDelegate(myDelegate);  
  11.         //use a delegate for processing  
  12.         string res = delObj(FirstName, LastName);  
  13.         Console.WriteLine("Full Name :" + res);  
  14.         Console.ReadLine();  
  15.     }  
  16. }
