本文实例讲述了C#实现用于生成条形码的类。分享给大家供大家参考。具体如下:

这个C#类可以用来生成39码 12位标准条形码

using System.Collections;
using System.Text.RegularExpressions;
namespace DotNet.Utilities
{
  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(‘C‘, "110110100101");
      ht.Add(‘D‘, "101011001011");
      ht.Add(‘E‘, "110101100101");
      ht.Add(‘F‘, "101101100101");
      ht.Add(‘G‘, "101010011011");
      ht.Add(‘H‘, "110101001101");
      ht.Add(‘I‘, "101101001101");
      ht.Add(‘J‘, "101011001101");
      ht.Add(‘K‘, "110101010011");
      ht.Add(‘L‘, "101101010011");
      ht.Add(‘M‘, "110110101001");
      ht.Add(‘N‘, "101011010011");
      ht.Add(‘O‘, "110101101001");
      ht.Add(‘P‘, "101101101001");
      ht.Add(‘Q‘, "101010110011");
      ht.Add(‘R‘, "110101011001");
      ht.Add(‘S‘, "101101011001");
      ht.Add(‘T‘, "101011011001");
      ht.Add(‘U‘, "110010101011");
