FIFO with winform in C#

Question

I'm getting annoyed with GUI problems in my threads. How do i create a FIFO so my main form/thread will receive data to do things instead of having my threads use a callback and run the code (and fail) themselves?

Answer 1

Use SynchronizationContext to Post/Send "calls" to the UI thread.

Answer 2

BeginInvoke on a Winform control, to make a call across threads, will use the Window's message queue, which is FIFO.

Answer 3

If you have a handle to the main form (or any control), you can use Control.Invoke / Control.BeginInvoke.

If you don't want to hand out a Control instance, you can give external code an ISynchronizeInvoke instance (any control will do it, or write your own class that wraps a Control to prevent caller-casting). Then the caller can use this to perform methods.

Finally, consider using events; the running code raises events that your UI handles; the UI can then call Control.Invoke locally to process the data.
