C#: How do you access an integer in the main UI thread from another thread?

Question

How do you access an integer (increment nCount++) in the main form from the method of an asynchronous callback function?

I know that with methods you have to check if invoke is required, then call begininvoke for the intended method as a delegate, as to avoid an illegal threading operation, but how an you perform a simple operation such as nCount++ from another thread?

Answer 1

Interlocked.Increment(ref variable);
