WPF Byte array to BitmapImage

Question

I read all first page results of "Byte array to BitmapImage" and I fount Byte array to BitmapImage WP byte[] to BitmapImage in silverlight the problem is that I code dosen't work for me and I get this error:

'System.Windows.Media.Imaging.BitmapImage' does not contain a definition for 'SetSource' and no extension method 'SetSource' accepting a first argument of type 'System.Windows.Media.Imaging.BitmapImage' could be found (are you missing a using directive or an assembly reference?)

My main code is:

int stride = CoverPhotoBitmap.PixelWidth * 4;
int size = CoverPhotoBitmap.PixelHeight * stride;
byte[] CoverPhotoPixels = new byte[size];
CoverPhotoBitmap.CopyPixels(CoverPhotoPixels, stride, 0);

byte[] HiddenPhotoPixels = new byte[size];
HiddenPhotoBitmap.CopyPixels(HiddenPhotoPixels, stride, 0);
ResultPhotoBitmap = ByteArraytoBitmap(HiddenPhotoPixels);

and my method is:

public static BitmapImage ByteArraytoBitmap(Byte[] byteArray)
{
    MemoryStream stream = new MemoryStream(byteArray);
    BitmapImage bitmapImage = new BitmapImage();
    bitmapImage.SetSource(stream);
    return bitmapImage;
}

How you want to use this bitmap, do you want to set it to Image control? — Amer

You want to set the Source property instead of calling the SetSource method of the Silverlight BitmapImage. Anyway, that won't help, because it required an encoded image buffer (like PNG or JPEG) which you don't have. You'll have to create a BitmapSource from the byte array, or write a byte array to a WriteableBitmap. — Clemens

@Clemens As you see I used the question that Jcl suggest to me and solved my later question, my current question is what is SetSource alternative in WPF. — Mostafa Mohammadi

The example you found appears to have been specific to Silverlight. The exception explains that the method you called(SetSource) does not exist. What you need to do is set the StreamSource.

public static BitmapImage ByteArraytoBitmap(Byte[] byteArray)
{
    MemoryStream stream = new MemoryStream(byteArray);

    BitmapImage bitmapImage = new BitmapImage();
    bitmapImage.BeginInit();
    bitmapImage.StreamSource = stream;
    bitmapImage.EndInit();

    return bitmapImage;
}
