问题描述

朋友，

我想生成9的代码3，以通过textbox(string)输入.我也想将条形码保存在数据库中.
我下载了条形码字体并安装并尝试了以下代码.

Hi Friend,

I want to generate code 3 of 9 for input through textbox(string). I want to save that barcode in database also.
I downloaded the barcode font and installed and tried the following code.

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
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 WebForm1.
    /// </summary />
    public class WebForm1 : System.Web.UI.Page
    {
        protected System.Web.UI.WebControls.Image myBarCode;
    
        private void Page_Load(object sender, System.EventArgs e)
        {
            // Put user code to initialize the page here
            myBarCode.ImageUrl = "BarCode.aspx?code=31231";
        }

        #region Web Form Designer generated code
        override protected void OnInit(EventArgs e)
        {
            //
            // CODEGEN: This call is required by the ASP.NET Web Form Designer.
            //
            InitializeComponent();
            base.OnInit(e);
        }
        
        /// <summary />
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary />
        private void InitializeComponent()
        {    
            this.Load += new System.EventHandler(this.Page_Load);

        }
        #endregion
    }
}

还创建了asp:image对象.但是我遇到了错误.

您能帮我编码吗?

BarCode barcode = new BarCode();

// Set barcode symbology type to Code-39 in C#
barcode.SymbologyType = SymbologyType.Code39;

// Set Code39 barcode value in C#
barcode.CodeText = "CODE39";

// Set Code39 drawing image format to PNG in C#
barcode.Format = ImageFormat.Png;

// Generate Code-39 barcode & encode to the png image in C#
barcode.drawBarcode("C://barcode-code39-csharp.png");

// Generate Code-39 barcode & print to System.Drawing.Graphics object in C#
barcode.drawBarcode("Graphics object");

// Create Code-39 barcode & draw to System.IO.Stream object in C#
barcode.drawBarcode("Stream object");
