string[] s = { "ClientBin" };
string url = App.Current.Host.Source.OriginalString.ToString().Split(s, StringSplitOptions.RemoveEmptyEntries)[0] + tr.IMG.ToString().Trim(new char[]{'.','/'});
ImageBrush br = new ImageBrush();
br.ImageSource = new BitmapImage(new Uri(url, UriKind.RelativeOrAbsolute));
but.setIcon(br);
最主要的是 App.Current.Host.Source.OriginalString 获取路径为 http://localhost:8080/ClientBin/XXX.xap
