使用谷歌Z生成条形码以及二维码

下载地址:http://zxingnet.codeplex.com/

zxing.net是.net平台下编解条形码和二维码的工具,使用非常方便。

首先下载二进制dll文件,引入工程;

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using ZXing.QrCode;
using ZXing;
using ZXing.Common;
using ZXing.Rendering;

namespace zxingTest
{
    public partial class Form1 : Form
    {
        EncodingOptions options = null;
        BarcodeWriter writer = null;

        public Form1()
        {
            InitializeComponent();
            options = new QrCodeEncodingOptions
            {
                DisableECI = true,
                CharacterSet = "UTF-8",
                Width = pictureBoxQr.Width,
                Height = pictureBoxQr.Height
            };
            writer = new BarcodeWriter();
            writer.Format = BarcodeFormat.QR_CODE;
            writer.Options = options;
        }

        private void buttonQr_Click(object sender, EventArgs e)
        {
            if (textBoxText.Text == string.Empty)
            {
                MessageBox.Show("输入内容不能为空!");
                return;
            }
            Bitmap bitmap = writer.Write(textBoxText.Text);
            pictureBoxQr.Image = bitmap;
        }
    }
}

 将字符编码时可以指定字符格式;默认为ISO-8859-1英文字符集,但一般移动设备常用UTF-8字符集编码,

可以通过QrCodeEncodingOptions设置编码方式。

如果要生成其他zxing支持的条形码,只要修改BarcodeWriter.Format就可以了

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using ZXing.QrCode;
using ZXing;
using ZXing.Common;
using ZXing.Rendering;

namespace zxingTest
{
    public partial class Form1 : Form
    {
        EncodingOptions options = null;
        BarcodeWriter writer = null;

        public Form1()
        {
            InitializeComponent();
            options = new EncodingOptions
            {
                //DisableECI = true,
                //CharacterSet = "UTF-8",
                Width = pictureBoxQr.Width,
                Height = pictureBoxQr.Height
            };
            writer = new BarcodeWriter();
            writer.Format = BarcodeFormat.ITF;
            writer.Options = options;
        }

        private void buttonQr_Click(object sender, EventArgs e)
        {
            if (textBoxText.Text == string.Empty)
            {
                MessageBox.Show("输入内容不能为空!");
                return;
            }
            Bitmap bitmap = writer.Write(textBoxText.Text);
            pictureBoxQr.Image = bitmap;
        }
    }
}
