Error while Setting source to BitmapImage

Question

I am a WP7 developer. I was using the following function:

public BitmapImage SetImageSource(byte[] byteArray)
{
    BitmapImage bitmap = new BitmapImage();          
    try
    {
        MemoryStream ms = new MemoryStream(byteArray, 0, byteArray.Length);
        bitmap.SetSource(ms);
        ms.Flush();
        ms.Dispose();
    }

    catch (Exception ex)
    {
       MessageBox.Show(ex.Message);
    }
    return bitmap;
}

to write a byteArray to a bitmap image. But in some cases it fires the exception as:

System.OutOfMemoryException was unhandled
Message=OutOfMemoryException
StackTrace:

       at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)

I using the try..catch block to catch the exception but exception is not caught.

Did the exception appear on both a device and the emulator ? — Alexis Mathieu, Jun 18 '12 at 09:42
yes.. when i run the application first time its ok but when i navigate to the page of image list continuously, the exception occurs — user1463008, Jun 18 '12 at 11:09
Can you provide more information/code about the context where this function is used please ? — Alexis Mathieu, Jun 20 '12 at 08:17

I made this function and doing this way

  private BitmapSource ConvertPic(Stream Image)
        {
            BitmapSource ContactImage;
            if (Image == null)
            {
                return ContactImage = null;
            }
            var bmp = new BitmapImage();
            bmp.SetSource(Image);
            ContactImage = bmp;
            return ContactImage;
        }
