I am trying to print a barcode in my web page.

string barcode = Label23.Text;
        Bitmap bitmap = new Bitmap(barcode.Length * 40,150);
        using (Graphics graphics = Graphics.FromImage(bitmap))
        {
            Font ofont = new System.Drawing.Font("IDAutomationHC39M", 20);
            PointF point = new PointF(2f, 2f);
            SolidBrush black = new SolidBrush(Color.Black);
            SolidBrush white = new SolidBrush(Color.White);
            graphics.FillRectangle(white, 0, 0, bitmap.Width, bitmap.Height);
            graphics.DrawString("*"+barcode+"*",ofont,black,point);

        }
        using (MemoryStream ms = new MemoryStream())
        {
            string mypath = Request.PhysicalApplicationPath + "Images\\";
            bitmap.Save(mypath+ "barcode.png",ImageFormat.Png);
            Image2.ImageUrl = "~/Images/barcode.png";


        }

What I have tried:

instead of getting the barcode i am getting the text that i enter.

When I was generating and displaying bar codes I used Brad Barnhill's library he wrote an article about it here Barcode-Image-Generation-Library

First you need to check the font "IDAutomationHC39M" working fine on your machine.

Then use below code

Here path is any local path like @c:\Image\

C#

public void CreateBarcode(string data) {
var imgPath = string.Format("{0}{1}.png", path, data);
Bitmap barcode = new Bitmap(1, 1);
Font threeOfNine = new Font("IDAutomationHC39M", 60,
System.Drawing.FontStyle.Regular,
System.Drawing.GraphicsUnit.Point);
Graphics graphics = Graphics.FromImage(barcode);
SizeF dataSize = graphics.MeasureString(data, threeOfNine);
barcode = new Bitmap(barcode, dataSize.ToSize());
graphics = Graphics.FromImage(barcode);
graphics.Clear(Color.White);
graphics.TextRenderingHint = TextRenderingHint.SingleBitPerPixel;
graphics.DrawString(data, threeOfNine, new SolidBrush(Color.Black), 0, 0);
graphics.Flush();
threeOfNine.Dispose();
graphics.Dispose();
barcode.Save(imgPath);
}
