First, tag what do you want to use: WPF or System.Drawing? Secondly, why? What do you want to do with IntPtr?

If this is System.Drawing.Bitmap, use GetHbitmap.

Again, the question is: why? Chances are, what you want you can do using pure .NET libraries. Also, check up carefully if you really want to use PictureBox. If you want to manipulate image, or animate or do anything interactive, PictureBox will only eat up some extra resources but won't provide any help, will only add some hassles. I explained it, and also explained what to do instead, in my past solutions:
How to keep the image Drawn in PictureBox[^],
Picture box lose drawing after reloading[^],
How do I clear a panel from old drawing[^].
