分享一个C#创建Barcode的DLL

用于工作需要产生Barcode，随手从网上找了一个DLL（原文地址忘了）

http://files.VEVb.com/panchunting/barcode_bin.zip

使用非常简单，只需添加引用，然后编码如下

using System;using System.Collections.Generic;using System.Drawing;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using BarcodeLib;namespace WebAppBarcode{    public partial class GetBarCodeImage : System.Web.UI.Page    {        PRotected void Page_Load(object sender, EventArgs e)        {            string strEncode = Request.QueryString["Code"];            CreateImage(strEncode);        }        private void CreateImage(string Code)        {            BarcodeLib.Barcode barcode = new BarcodeLib.Barcode()            {                IncludeLabel = true,                Alignment = AlignmentPositions.CENTER,                Width = 300,                Height = 100,                RotateFlipType = RotateFlipType.RotateNoneFlipNone,                BackColor = Color.White,                ForeColor = Color.Black,            };            System.Drawing.Image img = barcode.Encode(TYPE.CODE128B, Code);            using (System.IO.MemoryStream ms = new System.IO.MemoryStream())            {                img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);                Response.ClearContent();                Response.ContentType = "image/png";                Response.BinaryWrite(ms.ToArray());            }        }    }}

调用后台页面

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;namespace WebAppBarcode{    public partial class _Default : Page    {        protected void Page_Load(object sender, EventArgs e)        {        }        protected void Button1_Click(object sender, EventArgs e)        {            imgBarcode.Src = "~/GetBarCodeImage.aspx?Code=" + this.TextBox1.Text;        }    }}

调用前台代码

    <ol class="round">        <li>            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>            <asp:Button ID="Button1" runat="server" Text="Barcode" OnClick="Button1_Click" />        </li>        <li>            <img id="imgBarcode" runat="server" style="height: 20mm; width: 100mm;" />        </li>    </ol>

最终效果如下

多说一句，img的长度要设长一点，尤其当字符比较长的时候，否则可能扫描枪无法扫出
