How to Convert byte array to ImageSource for Windows 8.0 store application

Question

I am working on Windows 8 store application. I am new at it.

I am receiving an image in the form of byte array (byte []).

I have to convert this back to Image and display it in Image Control.

so far I have button and Image control on Screen. When I click button, I call following function

private async Task LoadImageAsync()
{
    byte[] code = //call to third party API for byte array
    System.IO.MemoryStream ms = new MemoryStream(code);
    var bitmapImg = new Windows.UI.Xaml.Media.Imaging.BitmapImage();

    Windows.Storage.Streams.InMemoryRandomAccessStream imras = new Windows.Storage.Streams.InMemoryRandomAccessStream();

    Windows.Storage.Streams.DataWriter write = new Windows.Storage.Streams.DataWriter(imras.GetOutputStreamAt(0));
    write.WriteBytes(code);
    await write.StoreAsync();
    bitmapImg.SetSourceAsync(imras);
    pictureBox1.Source = bitmapImg;
}

This is not working properly. any idea? When I debug, I can see the byte array in ms. but it is not getting converted to bitmapImg.

Answer 1

I found the following on Codeproject

public class ByteImageConverter
{
    public static ImageSource ByteToImage(byte[] imageData)
    {
        BitmapImage biImg = new BitmapImage();
        MemoryStream ms = new MemoryStream(imageData);
        biImg.BeginInit();
        biImg.StreamSource = ms;
        biImg.EndInit();

        ImageSource imgSrc = biImg as ImageSource;

        return imgSrc;
    }
}

This code should work for you.
