using System;
using System.Threading;
namespace TaskDemo {
public class MyTask {
public Thread m_thread;
string m_name;
public MyTask(string name) {
m_name = name;
m_thread = new Thread(new ThreadStart(Worker)); // 线程创建，作为一个类的成员存在
}
private void Worker() {
Console.WriteLine("Hello, ");
Thread.Sleep(1500);
Console.WriteLine(m_name);
}
}
class TaskDemo1 {
static void Main(string [] args) {
MyTask task1 = new MyTask("Bill");
MyTask task2 = new MyTask("Steve");
task1.m_thread.Start(); //线程启动
task2.m_thread.Start();
}
}
}
关闭窗口结束线程
private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
if(my_thread.ThreadState.ToString() =="Suspended") //先检查线程的状态
{
my_thread.Resume(); // 唤起
my_thread.Abort(); //杀死线程
my_thread.Join(); //这里是保证彻底的杀死线程吧
}
else
{
my_thread.Abort();
my_thread.Join();
}
}
上面用到了一个叫做join和函数，它的作用是什么？
t.Join();
可以这么理解,把线程t放到当前位置来执行,只有t结束以后才会执行t.Join()以后的代码
