Asp.Net MVC实现文字,链接生成二维码

1、创建MVC项目

2、添加NuGet程序包：ThoughtWorks.QRCode

3、在控制器书写对应代码

    [HttpPost]     
    public ActionResult EWMTest(string txtQRContext)
    {
        string strContent = txtQRContext;
        MemoryStream ms = new MemoryStream();

        // 生成二维码
        QRCodeEncoder qrCodeEncoder = new QRCodeEncoder();
        qrCodeEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE;
        qrCodeEncoder.QRCodeScale = 4;
        qrCodeEncoder.QRCodeVersion = 7;
        qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.M;
        //kedee 增加utf-8编码，可支持中文汉字  
        Image image = qrCodeEncoder.Encode(strContent, System.Text.Encoding.UTF8); 
        Bitmap map = new Bitmap(image, new Size(200, 200));
        //end

        map.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);
        //  将图片内存流转成base64,图片以DataURI形式显示
        string strUrl = "data:image/gif;base64," + Convert.ToBase64String(ms.ToArray());           
        image.Dispose();
        ms.Dispose();
        //  显示
        ViewBag.src = strUrl;
        //前端显示：<img src="@ViewBag.src" />
        return View();
    }
