How do you implement a 'FileUploadCommand' using OpenFileDialog in Silverlight?

Question

Ok,

Wanting to MVVM an existing app. The code behind contains the following:

private void UploadClick(object sender, RoutedEventArgs e)
{
    /*
     * 1. Clear Messages (ObservableCollection)
     * 
     * 2. Create new OpenFileDialog
     * 3. if(ofd returns ok)
     *     Pass file to Interpreter
     */
}

Basically, what I'd like to know is, how would I 'Commandise' this? Should I use an OpenFileDialog in my command in the VM? - This seems wrong as the OFD is a way of passing in a file that is specific to the view.

But how would I do it? If I hook into the Click event, then call the VM, I'm not using commands...

??
