推荐答案

尝试这种方式:

try this way :

if (fuphotos.HasFile)
{
	Bitmap originalBMP = new Bitmap(fuphotos.FileContent);

                int origWidth = originalBMP.Width;
                int origHeight = originalBMP.Height;
		if(originalBMP .width==3  && originalBMP .height=4)
		{
			originalBMP .Save(directory + cfilename);
		}
		else
		{
			//show an error message
		}
}
