I’ve been playing around with Silverlight and WCF services and I came across the need to set the Source of an Image control in Silverlight from a byte array. I have a service method which returns an image from the server as a byte array which I want to show in the Silverlight application.

My service method is simple and looks like this:

using System.IO;

public byte[] GetImage(string serverPath)
{
    return File.ReadAllBytes(serverPath);
}

In the Silverlight application I create a MemoryStream from the byte array, then a BitmapImage from the MemoryStream and set the image source to the BitmapImage.

using System.IO;
using System.Windows.Media.Imaging;

void proxy_GetImageCompleted(object sender, GetImageCompletedEventArgs e)
{
    MemoryStream stream = new MemoryStream(e.Result);
    BitmapImage b = new BitmapImage();
    b.SetSource(stream);
    imgImage.Source = b;
}

proxy_GetImageCompleted is the event handler for when my asynchronous call to GetImage completes, where e.Result is the byte array.
