How to embedd data in barcode and string value with line break or space on a single barcode? I want to get the printed bar code on the basis of data entered in the PDF file. Following is the code I am using:

string barCode = txtCode.Text;
         System.Web.UI.WebControls.Image imgBarCode = new System.Web.UI.WebControls.Image();
         using (Bitmap bitMap = new Bitmap(barCode.Length * 40, 80))
         {
             using (Graphics graphics = Graphics.FromImage(bitMap))
             {
                 Font oFont = new Font("IDAutomationHC39M", 16);
                 PointF point = new PointF(2f, 2f);
                 SolidBrush blackBrush = new SolidBrush(Color.Black);
                 SolidBrush whiteBrush = new SolidBrush(Color.White);
                 graphics.FillRectangle(whiteBrush, 0, 0, bitMap.Width, bitMap.Height);
                 graphics.DrawString("*" + barCode + "*", oFont, blackBrush, point);
             }
             using (MemoryStream ms = new MemoryStream())
             {
                 bitMap.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
                 byte[] byteImage = ms.ToArray();

                 Convert.ToBase64String(byteImage);
                 imgBarCode.ImageUrl = "data:image/png;base64," + Convert.ToBase64String(byteImage);
             }
             plBarCode.Controls.Add(imgBarCode);
