如何设置线程完全结束后运行其他内容?

[文盲老顾]

public delegate void delegateHandle(object sender,EventArgs e);

public partial class FCPMClient : Form
{
   public event delegateHandle onFinished;
   private Thread thread = null;

   public FCPMClient()
   {
      InitializeComponent();
   }

   private void Form1_Load(object sender, EventArgs e)
   {
      thread = new Thread(new ThreadStart(fun1));
      thread.Start();
      this.onFinished += new delegateHandle(fun2);
   }

   private void fun1(){
      onFinished(this, new EventArgs());
   }

   private void fun2(object sender, EventArgs e){
      thread.Abort();
   }
}

我现在的需求是在某一个线程结束后运行某些代码，但我的程序类似上边这些，调用 fun2 时，实际上线程还在进行，并没有完全结束，这个要怎么解决？

这么搞，程序直接挂起了

[superliu1122]

public partial class FCPMClient : Form
{
EventWaitHandle eventWaitHandle = new ManualResetEvent(false);
   private Thread thread = null;

   public FCPMClient()
   {
      InitializeComponent();
   }

   private void Form1_Load(object sender, EventArgs e)
   {
      thread = new Thread(new ThreadStart(fun1));
      thread.Start();
      this.eventWaitHandle.WaitOne();
      fun2();
   }

   private void fun1(){
      this.eventWaitHandle.Set();
   }

   private void fun2(object sender, EventArgs e){
      
   }
}

thread.Join或者用其他方式，比如event触发，委托触发等

[文盲老顾]

问题是，fun2 就是触发后运行的内容，但是，这个是在线程内触发的，在执行 fun2 时，thread 并没有完全结束

[SocketUpEx]

在fun1最后通知程序执行fun2

[文盲老顾]

我是使用 Timer 组件定时检查，当 thread.IsAlive 的值是 false 时，确认线程完全结束，除了这个，有没有其他方法？

按1L的做法就行了吧！

private Thread thread = null;

        private void Form1_Load(object sender, EventArgs e)
        {
            thread = new Thread(new ThreadStart(fun1));
            thread.Start();
            this.onFinished += new delegateHandle(fun2);
        }

        private void fun1()
        {
            onFinished(this, new EventArgs());
        }

        private void fun2(object sender, EventArgs e)
        {
            thread.Join();
            thread.Abort();
        }

感谢楼上的,不过这个方法不是我所希望的，我在程序内加上类似的代码，程序也是挂起的

因为在 fun1 内有很多处理过程，只有发生特定情况时，才会终止线程

[wushuai1346]

有没有试过 Task?这个也是多线程的,感觉比Thread好用.

Task<Int32> t = new Task<Int32>(n => Sum((Int32)n),100000000);
t.Start();
Task cwt = t.ContinueWith(task = > Console.WriteLine("The sum is: " + task.Result));

[lyso2008]

看你想怎么用多线程序：
1.如果是compute bound,用Task.ContinueWith或TaskFactory.ContinueXXXXXX
(1).参考:http://msdn.microsoft.com/en-us/library/system.threading.tasks.task.continuewith.aspx
(2).http://msdn.microsoft.com/en-us/library/dd321446.aspx
2.如果是用BeginXXX,EndXXX,就用callback.

[code=c#]
public delegate void delegateHandle();

public partial class FCPMClient : Form
{
public event delegateHandle onFinished;
private Thread thread = null;

public FCPMClient()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
thread = new Thread(new ThreadStart(fun1));
thread.Start();
label1.Text = "线程开始";
}

private void fun1(){
Thread.Sleep(3000);
onFinished mi = new onFinished(fun2);
}

private void fun2(){
label1.Text = "线程结束";
}
}
[/code]

private Thread thread = null;这句没用，去掉

 
public delegate void delegateHandle();

public partial class FCPMClient : Form
{
   public event delegateHandle onFinished;

   public FCPMClient()
   {
      InitializeComponent();
   }

   private void Form1_Load(object sender, EventArgs e)
   {
      thread = new Thread(new ThreadStart(fun1));
      thread.Start();
      label1.Text = "线程开始";
   }

   private void fun1(){
      Thread.Sleep(3000);
      onFinished  mi = new onFinished(fun2);
   }

   private void fun2(){
      label1.Text = "线程结束";
   }
}
