以上是这个生成二维码的方法类。

下面是生成其中一个类型的方法：

string filename = DateTime.Now.ToFileTime().ToString()+".jpg";            string err = string.Empty;            string s = Qr.OutQr4Card(txtModelCode.Text,txtFactory.Text,Sex,RimStyle,txtPrice.Text);            Qr.OutQrInfo(s, filename, out err);

 

另外还要引用ThoughtWorks.QRCode.dll文件。
