使用BarcodeLib.Barcode.ASP.NET生成条形码

生成条形码图片，然后在前台页面展示：

 <img id="img" src="Mobile/<%=url %>"/>

 public string url;

        protected void Page_Load(object sender, EventArgs e)
        {
            //string code = Get("6901028045575", 2, 60);

            //this.barcode.InnerHtml = code;

            BarcodeLib.Barcode.Linear ean13 = new BarcodeLib.Barcode.Linear();
            ean13.Type = BarcodeLib.Barcode.BarcodeType.EAN13;
            string code = "";
            ean13.Data = code;
            ean13.ImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg;
            ean13.BarColor = Color.Black;
            ean13.BarWidth = ;
            ean13.LeftMargin = ;
            ean13.RightMargin = ;
            string path = System.Web.HttpContext.Current.Request.MapPath("/Mobile/") + code + ".jpeg";
            ean13.drawBarcode(path);
            url = code + ".jpeg";
        }

传入data时需要传入12位的数字。

然后项目中添加引用

[csharp]  view plaincopy

    {
        System.Drawing.Image image;
        int width = , height = ;
        string fileSavePath = AppDomain.CurrentDomain.BaseDirectory + "BarcodePattern.jpg";
        if (File.Exists(fileSavePath))
            File.Delete(fileSavePath);
        GetBarcode(height, width, BarcodeLib.TYPE.CODE128, "20131025-136", out image, fileSavePath);  

        pictureBox1.Image  = Image.FromFile("BarcodePattern.jpg");
    }
    public static void GetBarcode(int height, int width, BarcodeLib.TYPE type, string code, out System.Drawing.Image image, string fileSaveUrl)
    {
        try
        {
            image = null;
            BarcodeLib.Barcode b = new BarcodeLib.Barcode();
            b.BackColor = System.Drawing.Color.White;//图片背景颜色
            b.ForeColor = System.Drawing.Color.Black;//条码颜色
            b.IncludeLabel = true;
            b.Alignment = BarcodeLib.AlignmentPositions.LEFT;
            b.LabelPosition = BarcodeLib.LabelPositions.BOTTOMCENTER;
            b.ImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg;//图片格式
            System.Drawing.Font font = new System.Drawing.Font("verdana", 10f);//字体设置
            b.LabelFont = font;
            b.Height = height;//图片高度设置(px单位)
            b.Width = width;//图片宽度设置(px单位)  

            image = b.Encode(type, code);//生成图片
            image.Save(fileSaveUrl, System.Drawing.Imaging.ImageFormat.Jpeg);  

        }
        catch (Exception ex)
        {

        }

利用 zxing.dll生成条形码和二维码  下载地址http://zxingnet.codeplex.com/

ZXing (ZebraCrossing)是一个开源的，支持多种格式的条形码图像处理库， 。使用该类库可以方便地实现二维码图像的生成和解析。 

下载zxing.dll 项目参照引用

[csharp]  view plaincopy
{
                MultiFormatWriter mutiWriter = new com.google.zxing.MultiFormatWriter();
                ByteMatrix bm = mutiWriter.encode(txtMsg.Text, com.google.zxing.BarcodeFormat.QR_CODE, , );
                Bitmap img = bm.ToBitmap();
                pictureBox1.Image = img;  

                //自动保存图片到当前目录
                string filename = System.Environment.CurrentDirectory + "\\QR" + DateTime.Now.Ticks.ToString() + ".jpg";
                img.Save(filename, System.Drawing.Imaging.ImageFormat.Jpeg);
                lbshow.Text = "图片已保存到：" + filename;
            }
            catch (Exception ee)
            { MessageBox.Show(ee.Message); }
