How to get the length and width of the picture after uploading the picture in the fileupload control in C #?

You need to save the uploaded file first, and then use the Bitmap class to intercept it and obtain it through the instance's Size property.

How is the complete sentence written?

oppressor

int xx = new Bitmap (filename);
filename is the picture name
This is incorrect, how do you write it?

After PostedFile.SaveAs
       Bitmap i = New Bitmap (fn, True);
      i.Width;
i.Height;
That's it
C # never used, syntax is not wrong

Still not working, what does your fn mean?
