You'd be better off using the BackgroundWorker since you can pass in parameters to it.

Could u simply explain how BackgroundWorker pass parameters? I think it DoWork() take a event handler.

You call worker.RunWorkerAsync(object parameter) and in the do work event handler you can grab the object from the Argument property on DoWorkEventArgs.

It seems only working for one parameter, how about two?

I got a error with message in DoWork(), could u please explain why this will happen
Invalid cross-thread access.

You can't set things in your UI from code in the background thread (or any thread except the UI thread).
What are you trying to accomplish in DoWork?

For two parameters just create your own class that has the two parameters or use a KeyValuePair.
