多个委托方法的顺序执行
using System;
namespace 委托和事件
{
internal class Program
{
private static void Main(string[] args)
{
Action action = One;
action += Two;
action += Three;
Delegate[] delegates = action.GetInvocationList(); //返回委托挂接的方法，通过他可以控制委托方法执行顺序
foreach (Action delegateAction in delegates)
{
try
{
delegateAction();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
Console.Read();
}
private static void One()
{
Console.WriteLine("调用：方法一");
throw new Exception("Err in one");
}
private static void Two()
{
Console.WriteLine("调用：方法二");
}
private static void Three()
{
Console.WriteLine("调用：方法三");
