Read extended image properties in c#

Question

I would like to find the height/width of an image on disk without opening it, if possible (for performance reasons).

The Windows properties pane for images contains information like width, height, bit depth, etc., which leads me to believe that it is storing metadata on the file somewhere. How can I access this information?

Answer 1

Use System.Drawing.Image class.

        Image img = Image.FromFile(fileName);
        ImageFormat format = img.RawFormat;
        Console.WriteLine("Image Type : "+format.ToString());
        Console.WriteLine("Image width : "+img.Width);
        Console.WriteLine("Image height : "+img.Height);
        Console.WriteLine("Image resolution : "+(img.VerticalResolution*img.HorizontalResolution));

        Console.WriteLine("Image Pixel depth : "+Image.GetPixelFormatSize(img.PixelFormat));
        Console.WriteLine("Image Creation Date : "+creation.ToString("yyyy-MM-dd"));
        Console.WriteLine("Image Creation Time : "+creation.ToString("hh:mm:ss"));
        Console.WriteLine("Image Modification Date : "+modify.ToString("yyyy-MM-dd"));
        Console.WriteLine("Image Modification Time : "+modify.ToString("hh:mm:ss"));
