图片无法序列化后传输，但我们可以将图片转二进制字符串传输。然后在服务端将二进制字符串转图片。
将图片转字符串的例子:
private byte[] BmpToJpegBuff(Image img)
{
ImageConverter converter = new ImageConverter();
byte[] bmpSrc = (byte[])converter.ConvertTo(img, typeof(byte[]));
MemoryStream ms = new MemoryStream(bmpSrc);
MemoryStream msjpg = new MemoryStream();
Bitmap myBitmap = new Bitmap(ms);
myBitmap.Save(msjpg,ImageFormat.Jpeg);
byte[] bjpeg = msjpg.GetBuffer();
return bjpeg;
}
byte[] imgByte=BmpToJpegBuff(image);
string imgString = String.Join(",", Array.ConvertAll(imgByte, (Converter<byte, string>)Convert.ToString));
字符串转图片的例子。
string[] imgArr = imgData.Split(new char[] { ',' });
byte[] bty = Array.ConvertAll<string, byte>(imgArr, delegate(string s) { return byte.Parse(s); });
Bitmap bmp = new Bitmap(FromBytes(bty));
///
/// 字节转图片
///
public Image FromBytes(byte[] bs)
{
if (bs == null) return null;
try
{
MemoryStream ms = new MemoryStream(bs);
Image returnImage = Image.FromStream(ms);
ms.Close();
return returnImage;
}
catch { return null; }
