问题描述
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。。。。
问题解答
回答1：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.BinaryWrite(ms.ToArray());//这里的Write改成BinaryWrite即可 context.Response.End();
