Get stream from absolute Uri - windows-phone-7

Question

I'm working with Windows Phone 7 and I have a very difficult problem. Please help me !
I want to get a stream form an absolute uri (from web) of a png image. But GetResourceStream method work only with relative uri. Then I found imagetool form http://imagetools.codeplex.com/ but to now my problem is not still solved.
Could anyone give me a solution ?

Answer 1

How about using HttpWebRequest and HttpWebResponse?
var uri = new Uri("http://chriskoenig.net/wp-content/uploads/2011/04/givecamp_125125_ad.jpg", UriKind.Absolute);
HttpWebRequest request = HttpWebRequest.Create(uri) as HttpWebRequest;
request.BeginGetResponse((ar) =>
{
var response = request.EndGetResponse(ar);
Dispatcher.BeginInvoke(() =>
{
using (var stream = response.GetResponseStream())
{
var image = new BitmapImage();
image.SetSource(stream);
MyImage.Source = image;
}
});
}, null);

Try this simple Code Image stream from Absolute url and store to isolated storage
namespace eQuadrigaWP7
{
public class ItemViewModel : INotifyPropertyChanged
{
private string _imgURL;
public string imgURL
{
get
{
return _imgURL;
}
set
{
if (value != _imgURL)
{
_imgURL = value;
}
}
}
private BitmapImage _Image;
public BitmapImage Iimage
{
get
{
return _Image;
}
set
{
if (value != _Image)
{
_Image = value;
}
}
}
public void LoadIimage()
{
if (this.imgURL == null) throw new Exception("Error equadriga log");
HttpWebRequest downloadthumbnailrequest = (HttpWebRequest)WebRequest.Create(new Uri(this._imgURL)); ///this is main
DownloadThumbNailState thumbnailState = new DownloadThumbNailState();
thumbnailState.AsyncRequest = downloadthumbnailrequest;
downloadthumbnailrequest.BeginGetResponse(new AsyncCallback(HandleThumNailDownLoadResponse),
thumbnailState);
}
private void HandleThumNailDownLoadResponse(IAsyncResult asyncResult)
{
DownloadThumbNailState thumbnailState = (DownloadThumbNailState)asyncResult.AsyncState;
HttpWebRequest downloadthumbnailrequest = (HttpWebRequest)thumbnailState.AsyncRequest;
thumbnailState.AsyncResponse = (HttpWebResponse)downloadthumbnailrequest.EndGetResponse(asyncResult);
Stream imageStream = thumbnailState.AsyncResponse.GetResponseStream();
byte[] b = new byte[imageStream.Length];
imageStream.Read(b,0,Convert.ToInt32(imageStream.Length));
imageStream.Close();
MemoryStream ms = new MemoryStream(b);
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
BitmapImage bmp = new BitmapImage();
bmp.SetSource(ms);
String tempJPEG = "logo.jpg";
using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
if (myIsolatedStorage.FileExists(tempJPEG))
{
myIsolatedStorage.DeleteFile(tempJPEG);
}
IsolatedStorageFileStream fileStream = myIsolatedStorage.CreateFile(tempJPEG);
WriteableBitmap wb = new WriteableBitmap(bmp);
Extensions.SaveJpeg(wb, fileStream, wb.PixelWidth, wb.PixelHeight, 0, 85);
fileStream.Close();
this.Iimage = bmp;
}
});
}
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged(String propertyName)
{
if (null != PropertyChanged)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
public class DownloadThumbNailState
{
public HttpWebRequest AsyncRequest { get; set; }
public HttpWebResponse AsyncResponse { get; set; }
}
}
}
ItemViewModel imageitem = new ItemViewModel();
imageitem.imgURL = "http://www.yoursite.in/bilder/9780199738663/titel.jpg";
imageitem.LoadIimage();

Try this one,
BitmaiImage bmp=new BitmaiImage();
Image image=new Image();
Uri url = new Uri("http://Ur url", UriKind.Absolute);
HttpWebRequest reqest = (HttpWebRequest)WebRequest.Create(url);
reqest.BeginGetResponse(DownloadImageCallback, reqest);
void DownloadImageCallback(IAsyncResult result)
{
HttpWebRequest req = (HttpWebRequest)result.AsyncState;
HttpWebResponse responce = (HttpWebResponse)req.EndGetResponse(result);
Stream s = responce.GetResponseStream();
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
bmp.SetSource(s);
image.Source=bmp;
});
}
