How to Create and Use a Delegate in C#?

The following example code demonstrates How to Create and Use a Delegate in C#.

Basically, a delegate is a class member that refers to a method. In other words, we can call a method using a delegate. However, the same delegate object can also point to another method with the matching signature.

using System;
namespace DelegatesDemo
{
    class Program
    {
        public int FindLength(string s)
        {
            return s.Length;
        }
        static void Main(string[] args)
        {
            Program ob = new Program();

            Func<string, int> ob1 = new Func<string, int>(ob.FindLength);
            int n = ob1("Hello, World!!!");
            Console.WriteLine("Length = " + n);
        }
    }
}
