Getting image height n width?

[Mustafa Rabie]

dear all,

i am writing an application where the user can upload his own picture. I
wanted to get the Width and Height of the uploaded picture. So i assigned
the uploaded image to an aspnet image control, but when i call the height
and width properties of the image control it returns "" since they are not
set. So how can i get this info?

thanks
mustafa

Easiest way is to load it into an Image object (System.Drawing.Image) and
query it from there.

So something along the lines of:

Image image = Image.FromStream(file.InputSteam);

Int32 height = image.Height;
Int32 width = image.Width;

image.Dispose();
(that may close the input stream, I'm not sure)
