To remove delegates from a multicast delegate, use the Remove method, the minus operator (-), or the -= assignment operator.

   
 

using System;

public delegate void DelegateClass();

public class Starter {
    public static void Main(){
         DelegateClass del=MethodA;
         del+=MethodB;
         del+=MethodC;
         del=del-MethodB;
         del();
     }
    public static void MethodA() {
        Console.WriteLine("MethodA...");
    }

    public static void MethodB() {
        Console.WriteLine("MethodB...");
    }

    public static void MethodC() {
        Console.WriteLine("MethodC...");
    }
}
