在Windows Phone 7上将图像转换为字节数组没有System.Drawing Dll任何其他方式？

Question

Byte[] result = (Byte[])new ImageConverter().ConvertTo(img1, typeof(Byte[]));

//I cant use Image Converter add Image Class ? Drawing dll 

MemoryStream ms = new MemoryStream();

img1.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

return ms.ToArray();

//Cannot see System.Drawing dll and there is no  sth like Drawing.Imaging...

首先，WP7中没有 system.drawing 。

您可以这样做：

MemoryStream ms = new MemoryStream();

wb.SaveJpeg(ms, myimage.PixelWidth, myimage.PixelHeight, 0, 100);
byte [] imageBytes = ms.ToArray();
