C# ta web sayfasındaki resmi Image olarak çekme.

Önceden C# ta web sayfasındaki resmi Bitmap olarak çekme ‘yi paylaşmıştım. Nette bu kodun Image nesne olarak çeken halini buldum.

public Image DownloadImage(string _URL)
        {
            Image _tmpImage = null;

            try
            {
                // Open a connection
                System.Net.HttpWebRequest _HttpWebRequest = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(_URL);

                _HttpWebRequest.AllowWriteStreamBuffering = true;

                // You can also specify additional header values like the user agent or the referer: (Optional)
                _HttpWebRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)";
                _HttpWebRequest.Referer = "http://www.google.com/";

                // set timeout for 20 seconds (Optional)
                _HttpWebRequest.Timeout = 20000;

                // Request response:
                System.Net.WebResponse _WebResponse = _HttpWebRequest.GetResponse();

                // Open data stream:
                System.IO.Stream _WebStream = _WebResponse.GetResponseStream();

                // convert webstream to image
                _tmpImage = Image.FromStream(_WebStream);

                // Cleanup
                _WebResponse.Close();
                _WebResponse.Close();
            }
            catch (Exception _Exception)
            {
                // Error
                Console.WriteLine("Exception caught in process: {0}", _Exception.ToString());
                return null;
            }

            return _tmpImage;
        }

kullanımıda böyleymiş.

// Download web image
Image _Image = null;
_Image = DownloadImage("http://www.yourdomain.com/sample-image.jpg");

// check for valid image
if (_Image != null)
{
    // show image in picturebox
    pictureBox1.Image = _Image;

    // lets save image to disk
    _Image.Save(@"C:\SampleImage.jpg");
}
