系統使用.NET4.5.1

程式碼如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using QRCoder;
using System.Drawing;
using System.IO;
public partial class _Default : System.Web.UI.Page
{
    protected void
 
 Page_Load(object sender, EventArgs e)
    {
        string strCode = "http://www.dotnetcms.org";
        QRCodeGenerator qrGenerator = new QRCoder.QRCodeGenerator();
        QRCodeData qrCodeData = qrGenerator.CreateQrCode(strCode, QRCodeGenerator.ECCLevel.Q);
        QRCode qrcode = new QRCode(qrCodeData);

        
 
// qrcode.GetGraphic 方法可參考最下發“補充說明”
        Bitmap qrCodeImage = qrcode.GetGraphic(5, Color.Black, Color.White, null, 15, 6, false);
        MemoryStream ms = new MemoryStream();
        qrCodeImage.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);

        // 如果想儲存圖片 可使用  qrCodeImage.Save(filePath);

        
 
// 響應型別
        Response.ContentType = "image/Jpeg";
        //輸出字元流
        Response.BinaryWrite(ms.ToArray());
    }
}
