WEB中如何生成并打印条形码 最近在做一套资产系统,需要用到条形码,可是以前没有做过这方面的东西,请问哪位做过条形码的生成和打印,麻烦告知一二,谢谢了 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 把条码打印控件做成CAB包.把控件接上去,在前台用JS调用就可以了啊! namespace BarCode{ public class BarCodeToHTML { public static string get39(string s, int width, int height) { Hashtable ht = new Hashtable(); #region 39码 12位 ht.Add('A', "110101001011"); ht.Add('B', "101101001011"); ...... ht.Add(' ', "100110101101"); #endregion s = "*" + s.ToUpper() + "*"; string result_bin = "";//二进制串 try { foreach (char ch in s) { result_bin += ht[ch].ToString(); result_bin += "0";//间隔,与一个单位的线条宽度相等 } } catch { return "存在不允许的字符!"; } string result_html = "";//HTML代码 string color = "";//颜色 foreach (char c in result_bin) { color = c == '0' ?
