OpenFileDialog for selecting more than 1 file with WPF

How can I implement an openfiledialog, which is able to do multiselecting? Do I need an extra libraray or is it also possible with the WPF-Control OpenFil开发者_如何学CeDialog?

I think there is a property of OpenFileDialog which is MultiSelect.

So you may do this.

OpenFileDialog dlg = new OpenFileDialog(); dlg.MultiSelect = true; dlg.Show();
