The only reliable way to kill a thread is to let the thread terminate normally. This means you need a way to notify a thread that it needs to terminate, and provide a way to wait for the thread to terminate if necessary. There's synchronization objects you can use. For example, EventWaitHandle. There's no need to "create my thread public", but you may need to keep contexts to your created threads somewhere, like in a collection in your form class. Mark

One way to gracefully terminate a thread is to set a volatile bool variable to some value and check this value inside the other thread, like this:

public void ButtonClickHandler(Object sender, EventArgs args)
{
requestStopThread = true; // this is a volatile bool variable
}

Inside your thread you need to check if this variable will be set to true and then terminate the thread in a correct way:

while(!requestStopThread)
{
// do some stuff, terminate otherwise
}

or

// do something
...

if(requestStopThread)
// terminate

// do something
...
