Hi all,

I want to return image as image type using its URL.
I found this function but it does not return an image .

WebResponse response;
Stream RemoteStream;
StreamReader SR;
WebRequest request = WebRequest.Create(URL);
response = request.GetResponse();
RemoteStream = response.GetResponseStream();
SR = new StreamReader(RemoteStream);
System.Drawing.Image img = System.Drawing.Image.FromStream(RemoteStream);
img.Save(URL, System.Drawing.Imaging.ImageFormat.Jpeg);
response.Close();
RemoteStream.Close();
SR.Close();

Thanks

I haven't understood what you want to do... can you explain a bit more?
Is your code in an ASP.NET page, or what?

I'm not sure what is wrong with your code, but this works for me, perhaps you can refactor it:

C++

WebRequest request = WebRequest.Create("http://www.dur.ac.uk/images/about/new/DurhamCastleCathedral.jpg");
request.Proxy.Credentials = CredentialCache.DefaultCredentials;
WebResponse response = request.GetResponse();
Image image = Image.FromStream(response.GetResponseStream());
image.Save(@"c:\foo.jpg", ImageFormat.Jpeg);
response.Close();

You should be able to read from the response stream into the output file stream directly, if you don't need the intermediate Image object. This will save memory, and might be quicker under certain circumstances.
