Save Silverlight webcam image (ImageSource) to Server

问题

This is as far as I've gotten. What code would I write to save a captured image to the server? Without any dialog prompting for a save location. Similar to the way Facebook does it. (I've been unable to find examples online)

void CaptureSource_CaptureImageCompleted(object sender, CaptureImageCompletedEventArgs e)
{
    capturedImage.ImageSource = e.Result;
    stopCapture(); // turns off webcam
}

It is not that simple.

1. Create a WCF service on the server.
2. Consume it on the silverlight client.
3. Call service method to send an image to the server.
4. Save it on the server with custom logic.

Or, if this is too complicated - follow this tutorial. It is rather compact RESTful approach demo.

I did i before, Firstly ImageTools is good library not must but a good library, you may use. Beside this you shoul check for permission for camera access. Then here is the code, Hope helps,

/Capture image part/

     _captureSource.CaptureImageCompleted += ((s, args) =>
        {
            //some other stuffs
            domainServiceObject.PR_PATIENTPHOTOs.Clear();

            photo = new PR_PATIENTPHOTO();              
            ImageTools.ExtendedImage eimg=args.Result.ToImage();
            var encoder=new ImageTools.IO.Png.PngEncoder();                                 

            Stream stream= eimg.ToStreamByExtension("png");
            if (stream.Length > 512000)
            {                    
                eimg= ExtendedImage.Resize(eimg, 240, new NearestNeighborResizer());                    
                stream = eimg.ToStreamByExtension("png");
            }

/Reload Image Part/

//note photo.photo is byte[]

        photo = domainServerObject.PR_PATIENTPHOTOs.FirstOrDefault();

        if (photo != null)
        {
            using (MemoryStream ms = new MemoryStream(photo.PHOTO, 0, photo.PHOTO.Length))
            {
                ms.Write(photo.PHOTO, 0, photo.PHOTO.Length);
                BitmapImage img = new BitmapImage();
                img.SetSource(ms);
                imagePatientPhoto.Source = img;
            }
        }
