richtextbox 里面的rtf问题

[W511522329]

  PictureBox pic = new PictureBox();
            pic.SizeMode = System.Windows.Forms.PictureBoxSizeMode.AutoSize;
            pic.BackColor = this.richTextBox2.BackColor;
            // pic.Image = global::LanQQ.Properties.Resources.Bar1;
            pic.Image = System.Drawing.Image.FromStream(System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("LanQQ.Resources." + (sender as DevComponents.DotNetBar.ButtonItem).Tag.ToString() + ".gif"));
            pic.Tag = sender.ToString();
            pic.Name = "123";
            richTextBox2.InsertControl(pic);

用rth显示为：{\rtf1\ansi\ansicpg936\deff0\deflang1033\deflangfe2052{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}}
\viewkind4\uc1\pard\lang2052\f0\fs17{\pict\wmetafile0
}\par
}
因为每个图片（gif）显示的结果都是{\pict\wmetafile0 }，不知道如何去区分，等待解决。
