winRT下，将WriteableBitmap转为byte[]类型（随笔）



byte[] ConvertBitmapToByteArray(WriteableBitmap bitmap)
        {
            using (Stream stream = bitmap.PixelBuffer.AsStream())
            using (MemoryStream memoryStream = new MemoryStream())
            {
                stream.CopyTo(memoryStream);
                return memoryStream.ToArray();
            }
   }

添加using System.Runtime.InteropServices.WindowsRuntime;
