Error “This stream does not support seek operations” in C#

Question

I\'m trying to get an image from an url using a byte stream. But i get this error message:

This stream does not support seek operations.<

Answer 1

With images, you don't need to read the number of bytes at all. Just do this:

Image img = null;
string path = "http://www.example.com/image.jpg";
WebRequest request = WebRequest.Create(path);
req.Credentials = CredentialCache.DefaultCredentials; // in case your URL has Windows auth
WebResponse resp = req.GetResponse();

using( Stream stream = response.GetResponseStream() ) 
{
    img = Image.FromStream(stream);
    // then use the image
}
