C# 委托简单示例

C# 委托类似于C函数指针示例使用:

 1 using System;
 2 using System.Reflection;
 3 
 4 namespace ConsoleApp7
 5 {
 6     class Program
 7     {
 8         delegate void PrintHello();
 9 
10         static void print1()
11         {
12             // 获取当前方法名
13             Console.WriteLine(MethodBase.GetCurrentMethod().Name + "  run....");
14         }
15         static void print2()
16         {
17             Console.WriteLine(MethodBase.GetCurrentMethod().Name + "  run....");
18         }
19         static void print3()
20         {
21             Console.WriteLine(MethodBase.GetCurrentMethod().Name + "  run....");
22         }
23 
24         static void Main(string[] args)
25         {
26             PrintHello test_print_del;
27             test_print_del = print1;
28             test_print_del += print2;
29             test_print_del += print3;
30 
31             test_print_del();
32             Console.WriteLine("=======移除方法=======");
33             test_print_del -= print2;
34             test_print_del();
35 
36             Console.ReadKey();
37         }
38     }
39 }

运行结果终端打印:
