c#学习笔记――委托

曾经多次碰到委托，但一直不太明白，今天看着教程做了个小程序，测试一下就明白了，哈哈！

         delegate   double  ProcessDelegate( double  param1,  double  param2);

         static   double  Mutiply( double  param1,  double  param2)
         {
            return param1 * param2;
        }

         static   double  Divide( double  param1,  double  param2)
         {
            return param1 / param2;
        }

 

调用如下：

 

            ProcessDelegate process;
            process  =   new  ProcessDelegate(Mutiply);
            Response.Write(process( 4.5 ,  3.3 ));
            Response.Write( " <br> " );
            process  =   new  ProcessDelegate(Divide);
            Response.Write(process( 10.2 ,  3.3 ));
