asp.net(C#)生成Code39条形码实例

这篇文章主要介绍了生形码实例条码可扫描出的友可以过来参考下，希望对大家有所帮助代码如:MSCL{//////生条码Code39///</summary>public{Hashtable//////放倍数///</summary>publicbyteMagnify{{returnm_Magnify;}{m_Magnify}}intm_Height40;//////图高///</summary>publicint{get{returnm_Height;}set{=value;}}Fontnull;//////字大小///</summary>publicViewFont{get{}set{m_ViewFont=}}publicCode39(){m_Code39.Add("A",m_Code39.Add("B",m_Code39.Add("C","1101101001010");m_Code39.Add("E",m_Code39.Add("F","1011011001010");
