static byte[] GetBarcode(int height, int width,BarcodeLib.TYPE type,
                                          string  code,out System.Drawing.Image image)
        {
            image=null;
            BarcodeLib.Barcode b = new BarcodeLib.Barcode();
            b.BackColor = System.Drawing.Color.White;
            b.ForeColor = System.Drawing.Color.Black;
            b.IncludeLabel = true;
            b.Alignment = BarcodeLib.AlignmentPositions.CENTER;
            b.LabelPosition = BarcodeLib.LabelPositions.BOTTOMCENTER;
            b.ImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg;
            System.Drawing.Font font = new System.Drawing.Font("verdana",10f);
            b.LabelFont = font;

            b.Height = height;
            b.Width = width;

            image = b.Encode(type, code);
            SaveImage(image, Guid.NewGuid().ToString("N")+".png");
            byte[] buffer = b.GetImageData(SaveTypes.GIF);
            return buffer;
        }

原博主的代码没有贴出保存图片的代码，现在加上

static  void  BuildBarcode()
       {
           System.Drawing.Image image;
           int width=250, height=100;
           byte[] buffer = GetBarcode(height, width, 
                    BarcodeLib.TYPE.CODE128, "Avx-(13614)-vR", out image);
       }

　static byte[] GetBarcode(int height, int width,BarcodeLib.TYPE type,
                                          string  code,out System.Drawing.Image image)
        {
            image=null;
            BarcodeLib.Barcode b = new BarcodeLib.Barcode();
            b.BackColor = System.Drawing.Color.White;
            b.ForeColor = System.Drawing.Color.Black;
            b.IncludeLabel = true;
            b.Alignment = BarcodeLib.AlignmentPositions.CENTER;
            b.LabelPosition = BarcodeLib.LabelPositions.BOTTOMCENTER;
            b.ImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg;
            System.Drawing.Font font = new System.Drawing.Font("verdana",10f);
            b.LabelFont = font;

            b.Height = height;
            b.Width = width;

            image = b.Encode(type, code);
            SaveImage(image, Guid.NewGuid().ToString("N")+".png");
            byte[] buffer = b.GetImageData(SaveTypes.GIF);
            return buffer;
        }

　　　　 private static void SaveImage(System.Drawing.Image image, string p)
        {
            //自动保存图片到指定目录中
            string stringfilename ="G:\" + p;
            image.Save(stringfilename, System.Drawing.Imaging.ImageFormat.Jpeg);
        }

使用该方法还需要一个动态链接库：

barcode.dll下载
