C# 线程 - 如何启动和停止线程

Question

Can anyone give me a headstart on the topic of threading? I think I know how to do a few things but I need to know how to do the following:

Setup a main thread that will stay active until I signal it to stop(in case you wonder, it will terminate when data is received). Then i want a second thread to start which will capture data from a textbox and should quit when I signal it to that of which occurs when the user presses the enter key.

Cheers!

This is how I do it...

public class ThreadA {
    public ThreadA(object[] args) {
        ...
    }
    public void Run() {
        while (true) {
            Thread.sleep(1000); // wait 1 second for something to happen.
            doStuff();
            if(conditionToExitReceived) // what im waiting for...
                break;
        }
        //perform cleanup if there is any...
    }
}

Then to run this in its own thread... ( I do it this way because I also want to send args to the thread)

private void FireThread(){
    Thread thread = new Thread(new ThreadStart(this.startThread));
    thread.start();
}
private void (startThread){
    new ThreadA(args).Run();
}

The thread is created by calling "FireThread()"

The newly created thread will run until its condition to stop is met, then it dies...

You can signal the "main" with delegates, to tell it when the thread has died.. so you can then start the second one...

Answer 2

Thread th = new Thread(function1);
th.Start();
th.Abort();

void function1(){
//code here
}

Answer 3

Use a static AutoResetEvent in your spawned threads to call back to the main thread using the Set() method. This guy has a fairly good demo in SO on how to use it.
