Load image into a Image object (System.Drawing.Image) and get width, height

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

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

image.Dispose();

okay, dumb question,

 

what do you mean by (File.InputSteam)? it doesn't work if I type exactly that in. do i have to create an InputStream object?

File.InputStream is the stream of the file you need width and height.

You can also use System.Drawing.Image image = System.Drawing.Image.FromFile("filename") instead of InputStream

Hell yes, that worked perfectly, thank you!!!!!!!!!!!!!!!!!!!!!!

 

The only small problem was that Image was an ambigious reference between System.Drawing and System.Web.UI.WebControls. I made a direct reference to it and it worked!
