首先，你必须下载一个免费的条形码字体。在本例中，我使用了IdAutomation中的IDAutomationHC39M。在这个例子中，我使用了条形码39.



然后这是代码：

First, you have to download a free barcode font. For this example, I used "IDAutomationHC39M" from IdAutomation. In this example, I used Barcode 39.

Then this is the code:

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Imaging;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace Barcodes
{

/// <summary />
/// Summary description for BarCode.
/// br mode="hold" />
public class BarCode : System.Web.UI.Page
{
    private void Page_Load(object sender, System.EventArgs e)
    {
         // Get the Requested code to be created.
         string Code = Request["code"].ToString();

         // Multiply the lenght of the code by 40 (just to have enough width)
         int w = Code.Length * 40;
    
        // Create a bitmap object of the width that we calculated and height of 100
         Bitmap oBitmap = new Bitmap(w,100);
    
        // then create a Graphic object for the bitmap we just created.
         Graphics oGraphics = Graphics.FromImage(oBitmap);
        
        // Now create a Font object for the Barcode Font
        // (in this case the IDAutomationHC39M) of 18 point size
        Font oFont = new Font("IDAutomationHC39M", 18);
        
        // Let's create the Point and Brushes for the barcode
        PointF oPoint = new PointF(2f, 2f);
         SolidBrush oBrushWrite = new SolidBrush(Color.Black);
         SolidBrush oBrush = new SolidBrush(Color.White);
            
        // Now lets create the actual barcode image
        // with a rectangle filled with white color
        oGraphics.FillRectangle(oBrush, 0, 0, w, 100);
            
        // We have to put prefix and sufix of an asterisk (*),
        // in order to be a valid barcode
        oGraphics.DrawString("*" + Code + "*", oFont, oBrushWrite, oPoint);
        
        // Then we send the Graphics with the actual barcode
        Response.ContentType = "image/jpeg" ;
         oBitmap.Save (Response.OutputStream, ImageFormat.Jpeg);
    }
}
}
