在asp.net中使用ThoughtWorks.QRCode出现问题，生成的图片发送前台不能显示。
QRCodeEncoder qrCodeEncoder = new QRCodeEncoder(); qrCodeEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE;
qrCodeEncoder.QRCodeScale = 4;
qrCodeEncoder.QRCodeVersion = 7;
qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.M;
Bitmap img = qrCodeEncoder.Encode("123456");
MemoryStream ms = new MemoryStream();
img.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);
context.Response.ClearContent();
context.Response.ContentType = "image/Gif";
context.Response.Write(ms.ToArray());
context.Response.End();
我想应该和验证码生成一样的才对，用一个image控件引入生成页面链接，但是窝的就是显示不粗来，是哪里出错了？表示生成的图片用windowsform的控件查看是显示正常的说。。。。
