WCF传输图片解决方案

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; }
