c# - Simple Delegate (delegate) vs. Multicast delegates -

i have gone through many articles still not clear difference between normal delegates create , multicast delegates.

public delegate void mymethodhandler(object sender); mymethodhandler handler = new mymethodhandler(method1); handler += method2; handler(someobject); 

the above delegate mymethodhandler call these 2 methods. multicast delegates come in. have read can call multiple methods afraid basic understanding delegates not correct.

this article explains pretty well:

delegate void del(string s);  class testclass {     static void hello(string s)     {         system.console.writeline("  hello, {0}!", s);     }      static void goodbye(string s)     {         system.console.writeline("  goodbye, {0}!", s);     }      static void main()     {         del a, b, c, d;          // create delegate object references          // method hello:         = hello;          // create delegate object b references          // method goodbye:         b = goodbye;          // 2 delegates, , b, composed form c:          c = + b;          // remove composed delegate, leaving d,          // calls method goodbye:         d = c - a;          system.console.writeline("invoking delegate a:");         a("a");         system.console.writeline("invoking delegate b:");         b("b");         system.console.writeline("invoking delegate c:");         c("c");         system.console.writeline("invoking delegate d:");         d("d");     } } /* output: invoking delegate a:   hello, a! invoking delegate b:   goodbye, b! invoking delegate c:   hello, c!   goodbye, c! invoking delegate d:   goodbye, d! */
