   关于ZXing 就不用多介绍了，本问主要介绍如何使用ZXing 生成条形码和二维码的图片。

   Release 版本的dll下载地址：http://zxingnet.codeplex.com/

   下载完成后在项目中引用ZXing.dll，然后做以下封装：

   

/// <summary>
    /// 产生二维码
    /// </summary>
    /// <param name="width">二维码的宽度</param>
    /// <param name="height">二维码的高度</param>
    /// <param name="Contents">二维码内容</param>
    /// <returns>生成的图片</returns>
    public static Bitmap CreateQRCode( string Contents,int width = 430, int height = 430)
    { 
       EncodingOptions options = null;
       BarcodeWriter writer = null;
 
       options = new QrCodeEncodingOptions
       {
         DisableECI = true,
         CharacterSet = "UTF-8",
         Width = width,
         Height = height
        };
        writer = new BarcodeWriter();
        writer.Format = BarcodeFormat.QR_CODE;
        writer.Options = options;
        Bitmap bitmap = writer.Write(Contents);
        return bitmap;
    }
    /// <summary>
    /// 产生条形码
    /// </summary>
    /// <param name="width">条形码图片的宽度</param>
    /// <param name="height">条形码图片的高度</param>
    /// <param name="Contents">条形码内容</param>
    /// <returns>生成的图片</returns>
    public static Bitmap CreateBarCode( string Contents,int width=530, int height=200)
    { 
         EncodingOptions options =null;
         BarcodeWriter writer =null;
 
         options = new QrCodeEncodingOptions
         {
           DisableECI = true,
           CharacterSet = "UTF-8",
           Width =  width,
           Height = height
         };
          writer = new BarcodeWriter();
          writer.Format = BarcodeFormat.CODE_128;
          writer.Options = options;
          Bitmap bitmap = writer.Write(Contents);
          return bitmap;
    }

   注意在生成条形码的时候 设置好合适的 BarcodeFormat
