新建Windows应用程序，加入引用ThoughtWorks.QRCode.dll，编写代码生成二维码。

using System;

using System.Drawing;

using System.Windows.Forms;

using ThoughtWorks.QRCode.Codec;

namespace QcCodeCreaterExp

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        private void button1_Click(object sender, EventArgs e)

        {

            Image image;

            try

            {

                QRCodeEncoder qrCodeEncoder = new QRCodeEncoder();

                qrCodeEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE;

                qrCodeEncoder.QRCodeScale = Convert.ToInt32(TextBox_QrCodeSize.Text);//尺寸

                qrCodeEncoder.QRCodeVersion = Convert.ToInt32(TextBox_QrCodeVersion.Text);//版本号

                qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.M;

                image = qrCodeEncoder.Encode(TextBox_QrCodeContent.Text);

            }

            catch (Exception ex)

            {

                image = null;

            }

            if (image != null)

            {

                pictureBox1.Image = image;

            }

        }

    }

}
