Assuming you are working with Lists of strings, you want to do this:

Textbox1.Text = String.Join(", ", testVar.Select(s => s).ToArray());

The reason I left the s => s lambda is that your list might not be of strings. So this construct will give you a chance to build your string items accordingly.
