c# RichTextbox Paste method

Question

How exactly works RichTextbox Paste method? I'd like insert images to RTB. If I use Clipboard.SetImage(image); and then RTB.Paste(); it works fine. But I'd like make it by my self. I've following code. But it doesn't work:

        byte[] byteArray = null;
        using (MemoryStream ms = new MemoryStream())
        {
            image.Save(ms, ImageFormat.Png);
            ms.Seek(0, 0);
            byteArray = ms.ToArray();
        }
        string hexString = "";
        foreach (byte b in byteArray)
        {
            hexString += b.ToString("x2");
        }

        string mpic = @"{\pict\pngblip\picw396\pich396\picwgoal225\pichgoal225 ";
        mpic += hexString;
        mpic += "}";

        Console.WriteLine(mpic);
        return mpic;

I found that in hexString is differend value than in richTextbox after use Paste() method.

This works fine if I use correct hexa value.

        string mpic = @"{\pict\wmetafile8\picw396\pich396\picwgoal225\pichgoal225 ";
        mpic += hexString;
        mpic += "}";

I think what I need just convert image to WMF hexa value. But I don't know how to do that.

This is what works if it helps:

Since you're actually creating your own RTF formatting, and appending it to the control, I'd think you could use something like:

RTB.Rtf += mpic;
