Question

Is there a C# / Windows Forms equivalent to Android's runOnUiThread?

For example, say I am running a (long-running) task on a worker thread and at the end I want to post the result to a GUI control (which of course I can't do from the worker thread). Is there a function as simple as runOnUiThread that would allow me to post that refresh-display for processing by the UI thread?

Answer 1

Each control in WinForms inherits the Invoke and BeginInvoke methods.

Invoke will run the delegate synchronously whereas BeginInvoke runs it asynchronously.

Answer 2

A typical way to do this is with a System.Windows.Forms.Control:

control.BeginInvoke((MethodInvoker)delegate { ... });

But, the control's handle must have already been initialized on the UI thread. A simple

IntPtr ignored = control.Handle;

on the UI thread will accomplish that.
