that code does not generate any barcode! or are you using a barcode font? Elaborate/clarify a bit to get a better answer

no i did not understand it properly and i only need to convert my output which is in the form of barcode to image and save it into local folder..

That code should work and is not complicated to understand. If you want to save the image on disk, then just using bitMap.Save() but specify a file path instead of a MemoryStream

Please check the below mentioned links for more info.

protected void btnGenerate_Click(object sender, EventArgs e)
    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();
            imgBarCode.ImageUrl = "data:image/png;base64," + Convert.ToBase64String(byteImage);
