Join()方法使所有的调用线程等待直到当前线程(已连接线程)终止或完成其任务。
参考以下示例 -
using System
using System.Threading
public class MyThread
{
public void Thread1()
{
for (int i = 0 i < 5 i++)
{
Console.WriteLine("Thread1 : "+i)
Thread.Sleep(500)
}
}
}
public class ThreadExample
{
public static void Main()
{
MyThread mt = new MyThread()
Thread t1 = new Thread(new ThreadStart(mt.Thread1))
Thread t2 = new Thread(new ThreadStart(mt.Thread1))
Thread t3 = new Thread(new ThreadStart(mt.Thread1))
t1.Start()
t1.Join()
t2.Start()
t3.Start()
}
}
执行上面示例代码，得到以下结果 -
Thread1 : 0
Thread1 : 1
Thread1 : 2
Thread1 : 3
Thread1 : 4
Thread1 : 0
Thread1 : 0
Thread1 : 1
Thread1 : 1
Thread1 : 2
Thread1 : 2
Thread1 : 3
Thread1 : 3
Thread1 : 4
Thread1 : 4
