im trying to download an image and show in a picturebox control...

i've already got so far:

PHP Code:
            WebClient wcClient = new WebClient();
            byte[] mBuffer = wcClient.DownloadData("http://www.vbforums.com/images/ads/current.gif"); 
but now i realised that in vb.net we have a function called CType() that isnt avaliable in C#..how do i convert that byte[]array into a bitmap image so i can show it in my picturebox without having to write it to the disk? lol
