Cleanest Way to Invoke Cross-Thread Events

Question

I find that the .NET event model is such that I'll often be raising an event on one thread and listening for it on another thread. I was wondering what the cleanest way to marshal an event from a background thread onto my UI thread is.

Based on the community suggestions, I've used this:

// earlier in the code mCoolObject.CoolEvent+=             new CoolObjectEventHandler(mCoolObject_CoolEvent); // then private void mCoolObject_CoolEvent(object sender, CoolObjectEventArgs args) {     if (InvokeRequired)     {         CoolObjectEventHandler cb =             new CoolObjectEventHandler(                 mCoolObject_CoolEvent);         Invoke(cb, new object[] { sender, args });         return;     }     // do the dirty work of my method here } 

Answer 1

I have some code for this online. It's much nicer than the other suggestions; definitely check it out.

Sample usage:

private void mCoolObject_CoolEvent(object sender, CoolObjectEventArgs args) {     // You could use "() =>" in place of "delegate"; it's a style choice.     this.Invoke(delegate     {         // Do the dirty work of my method here.     }); }
