C#委托

这里介绍一下C#的委托

委托的用处：1、方法参数化2、轮播

1、将方法参数化

public class Test
{
public delegate void TestEventHandler(string name);
public Test()
{
this.Start("run", this.Run);
} 
private void Start(string name, TestEventHandler testEventHandler)
{
testEventHandler(name);
}
private void Run(string name)
{
Console.WriteLine(name);
}
}

2.将方法绑定到委托，并轮播

public class Test
{
public delegate void TestEventHandler(string name);

public TestEventHandler testEventHandler;

public Test()
{
testEventHandler += Run1;
testEventHandler += Run2;
testEventHandler("run");
}
private void Run1(string name)
{
Console.WriteLine(name + "1");

}
private void Run2(string name)
{

Console.WriteLine(name + "2");
}
}

结果：

RUN1

RUN2

这就是轮播
