using System.Drawing;using ThoughtWorks.QRCode.Codec;using ThoughtWorks.QRCode.Codec.Data;using ThoughtWorks.QRCode.Codec.Util;

 

產生二維

 

 public Bitmap NewCode(string str)        {            //初始化二維碼產生工具            QRCodeEncoder qrCodeEncoder = new QRCodeEncoder();            qrCodeEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE;            qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.M;            qrCodeEncoder.QRCodeVersion = 0;            qrCodeEncoder.QRCodeScale = 4;            //將字串產生二維碼圖片            Bitmap image = qrCodeEncoder.Encode(str, Encoding.Default);            return image;        }

 

 

 public ActionResult Cre()        {                     Bitmap image = createcode.NewCode(content);            MemoryStream ms = new MemoryStream();            image.Save(ms, ImageFormat.Png);            Response.BinaryWrite(ms.GetBuffer());            return null;        }

 

<img src="@Url.Action("Cre")" />
