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

Examples

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

public delegate string myDelegate(string FirstName, string LastName);
public class Personal {
    public static string myDelegate(string FirstName, string LastName) {
        return FirstName + "" + LastName + "";
    }
    static void Main(string[] args) {
        string FirstName = "Manikandan";
        string LastName = "M";
        //Creating the Delegate object
        myDelegate delObj = new myDelegate(myDelegate);
        //use a delegate for processing
        string res = delObj(FirstName, LastName);
        Console.WriteLine("Full Name :" + res);
        Console.ReadLine();
    }
}
//Output: Manikandan M
