C's method for generating TWO DIMENSIONAL code

This article gives an example of how C# generates 2-dimensional code. Share to everybody for everybody reference. Specific implementation methods are as follows:

First, ThoughtWorks.QRCode.dll

The specific code is as follows:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Drawing;

using ThoughtWorks.QRCode.Codec;
namespace QRCodeUtil

{

    /// <summary>

    /// 2 D code generated 

    /// </summary>

    public class QRCodeHelper

    {

        #region  Get by link 2 D code 

        /// <summary>

        ///  Get by link 2 D code 

        /// </summary>

        /// <param name="link"> link </param>

        /// <returns> return 2 D code pictures </returns>

        public static Bitmap GetQRCodeBmp(string link)

        {

            QRCodeEncoder qrCodeEncoder = new QRCodeEncoder();

            qrCodeEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE;

            qrCodeEncoder.QRCodeScale = 4;

            qrCodeEncoder.QRCodeVersion = 0;

            qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.M;

            Bitmap bmp = qrCodeEncoder.Encode(link);
            return bmp;

        }

        #endregion
    }

}

Use examples are as follows:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Drawing;

using QRCodeUtil;
namespace SWX

{

    public partial class WebForm1 : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {

            Bitmap bmp = QRCodeHelper.GetQRCodeBmp(@"http://www.baidu.com/");

            string str = HttpContext.Current.Request.MapPath("\\aa.bmp");

            bmp.Save(str);

        }

    }

}
