Net中委托之二多播委托

public class MyDelegate
{
private delegate int NoParameterWithReturn();//1.声明委托
public static void Show()
{
NoParameterWithReturn method = new NoParameterWithReturn(ShowSomething);//2.委托的实例化
//多播委托
method += ShowSomething;//按顺序添加到方法列表
method += ShowSomething;
method += ShowSomething;
method += ShowSomething;
method -= ShowSomething;//从方法列表的尾部去掉且只去掉一个完全匹配
Console.WriteLine("method.Invoke()结果是{0}", method.Invoke());//3.委托实例的调用
}
private static int ShowSomething()
{
Console.WriteLine("这里是ShowSomething");
return 11;
}
}
class Program
{
//多播委托
static void Main(string[] args)
{
Console.WriteLine("欢迎来到流星小子博客学习");
MyDelegate.Show();
Console.Read();
}
