Thread.Join()用法的理解

Thread.Join()用法的理解

  指在一线程里面调用另一线程join方法时,表示将本线程阻塞直至另一线程终止时再执行  
  比如  

1using System;
2
3namespace TestThreadJoin
4{
5    class Program
6    {
7        static void Main()
8        {
9            System.Threading.Thread x = new System.Threading.Thread(new System.Threading.ThreadStart(f1));
10            x.Start();
11            Console.WriteLine("This is Main.{0}", 1);
12            x.Join();
13            Console.WriteLine("This is Main.{0}", 2);
14            Console.ReadLine();
15        }
16        static void f1()
17        {
18            System.Threading.Thread y = new System.Threading.Thread(new System.Threading.ThreadStart(f2));
19            y.Start();
20            y.Join();
21            Console.WriteLine("This is F1.{0}",1);
22        }
23
24        static void f2()
25        {
26            Console.WriteLine("This is F2.{0}", 1);
27        }
28    }
29}

这儿有三个线程在处理(包括主线程),大家可看看执行结果.
结果:
This is Main.1
This is F2.1
This is F1.1
This is Main.2

如果: 注释//  x.Join();
结果:
This is Main.1
This is Main.2
This is F2.1
This is F1.1

另外:大家可以看看以下几个方法的区别,有兴趣的朋友可以用上面的例子进行测试

Thread.Suspend():挂起线程,或者如果线程已挂起,则不起作用;
Thread.Resume():继续已挂起的线程;
Thread.Interrupt():中止处于 Wait或者Sleep或者Join 线程状态的线程;
Thread.Sleep():将当前线程阻塞指定的毫秒数;
