C# for Multithreading

Question

I am writing something in C# for Multithreading basically need to know how i can close a Windows Form which is in another Thread or update the label in that box showing a status also.

Basically when accessing controls including the form itself you have to marshal the call back to the thread on which the control was created which is normally the main UI thread. This sort of pattern can be used - I'm assuming that the other thread is still executing a method within the form you want to close: if (this.InvokeRequired) { this.Invoke((Action)(() => { this.Close(); })); } else { this.Close(); } You can of course replace this.Close() with any other code involving controls.
