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
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;
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 }
