关于Thread.join( )方法

        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  

using  System;
using  System.Threading;

namespace  TestThreadJoin
{
    
class Program
    
{
        
static void Main()
        
{
            System.Threading.Thread x 
= new System.Threading.Thread(new System.Threading.ThreadStart(f1));
            x.Start();
            Console.WriteLine(
"This is Main.{0}"1);
            x.Join();
            Console.WriteLine(
"This is Main.{0}"2);
            Console.ReadLine();
        }

        
static void f1()
        
{
            System.Threading.Thread y 
= new System.Threading.Thread(new System.Threading.ThreadStart(f2));
            y.Start();
            y.Join();
            Console.WriteLine(
"This is F1.{0}"1);
        }


        
static void f2()
        
{
            Console.WriteLine(
"This is F2.{0}"1);
        }

    }

}

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;
