关于委托小实例

用委托比较两个值大小或者字符串

delegate int DGCompare(objectv1,object v2);

object GetMax(object[] values,DGCompare comparor)

{

  object max=values[0];

  foreach(object obj in values)

    {

             if(comparor(obj,max)>0)

               {

                          max=obj;

                  } 

    }

  return max;

}

public int IntCompare(object value1,object value2)

{

int  one=(int)value1;

int two=(int)value2;

return one-two;

}

public staticint StringLenCompare(object v1, object v2)

{

    string s1 = (string)v1;

    string s2 = (string)v2;

    return s1.Length - s2.Length;

}

在main函数里面调用这个

object max=GetMax(new object[]{30,90,2,4,34},IntCompare);

下面这个是字符串比较

object[] values = new object[] {"aaa","b","cc你好cc","w","冷静"};
object max = GetMax(values, StringLenCompare);
