How to stop threads?

Question

Hi guys I start threads with such code:

    Thread[] thr;
    private void button1_Click(object sender, EventArgs e)
    {
        decimal value = numericUpDown2

You can use a CancellationToken to signal when the operation should stop.

1. Create a CancellationTokenSource as an instance field of your type that you initialize in the button click handler.

2. In your background method periodically check the IsCancellationRequested property of the Token in the token source, or call ThrowIfCancellationRequested() if you want it to just throw an exception if it is canceled.

3. When you want to stop the threads call Cancel on the token source.
