Csharp/C#教程：C#生成code128条形码的方法分享

本文实例讲述了物流条形码的C#实现方法，分享一下供大家参考。具体实现方法如下：

主要功能代码如下：

usingSystem; usingSystem.Collections.Generic; usingSystem.Data; usingSystem.Drawing; namespaceCode { classBarCode { publicclassCode128 { privateDataTablem_Code128=newDataTable(); privateuintm_Height=40;

调用代码为：

Code128_Code=newCode128(); _Code.ValueFont=newFont("宋体",20); System.Drawing.BitmapimgTemp=_Code.GetCodeImage("T26200-1900-123-1-0900",Code128.Encode.Code128A); imgTemp.Save(System.AppDomain.CurrentDomain.BaseDirectory+"\"+"BarCode.gif",System.Drawing.Imaging.ImageFormat.Gif);
