C#生成code128条形码的方法
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;
///<summary>
///高度
///</summary>
publicuintHeight{get{returnm_Height;}set{m_Height=value;}}
privateFontm_ValueFont=null;
///<summary>
///是否显示可见号码如果为NULL不显示号码
///</summary>
publicFontValueFont{get{returnm_ValueFont;}set{m_ValueFont=value;}}
privatebytem_Magnify=0;
///<summary>
///放大倍数
///</summary>
publicbyteMagnify{get{returnm_Magnify;}set{m_Magnify=value;}}
///<summary>
///条码类别
///</summary>
