生成条形码的函数

使用方法:
Response.Write(bar_code("21254",100,1,1));
第一个参数表示:要打印的字符
第二个参数表示:高度
第三个参数表示:单位宽度
第四个参数表示:是否打印数字在下面,等1时打印。

附函数代码:
public string bar_code(object str, int ch, int cw, int type_code)
        {
            string strTmp = str.ToString();
            string code = strTmp;
            strTmp = strTmp.ToLower();
            int height = ch;
            int width = cw;
            strTmp = strTmp.Replace("0", "_|_|__||_||_|");
            strTmp = strTmp.Replace("1", "_||_|__|_|_||");
            strTmp = strTmp.Replace("2", "_|_||__|_|_||");
            strTmp = strTmp.Replace("3", "_||_||__|_|_|");
            strTmp = strTmp.Replace("4", "_|_|__||_|_||");
            strTmp = strTmp.Replace("5", "_||_|__||_|_|");
            strTmp = strTmp.Replace("7", "_|_|__|_||_||");
            strTmp = strTmp.Replace("6", "_|_||__||_|_|");
            strTmp = strTmp.Replace("8", "_||_|__|_||_|");
            strTmp = strTmp.Replace("9", "_|_||__|_||_|");
            strTmp = strTmp.Replace("a", "_||_|_|__|_||");
            strTmp = strTmp.Replace("b", "_|_||_|__|_||");
            strTmp = strTmp.Replace("c", "_||_||_|__|_|");
            strTmp = strTmp.Replace("d", "_|_|_||__|_||");
            strTmp = strTmp.Replace("e", "_||_|_||__|_|");
            strTmp = strTmp.Replace("f", "_|_||_||__|_|");
            strTmp = strTmp.Replace("g", "_|_|_|__||_||");
            strTmp = strTmp.Replace("h", "_||_|_|__||_|");
            strTmp = strTmp.Replace("i", "_|_||_|__||_|");
            strTmp = strTmp.Replace("j", "_|_|_||__||_|");
            strTmp = strTmp.Replace("k", "_||_|_|_|__||");
            strTmp = strTmp.Replace("l", "_|_||_|_|__||");
            strTmp = strTmp.Replace("m", "_||_||_|_|__|");
            strTmp = strTmp.Replace("n", "_|_|_||_|__||");
            strTmp = strTmp.Replace("o", "_||_|_||_|__|");
            strTmp = strTmp.Replace("p", "_|_||_||_|__|");
            strTmp = strTmp.Replace("r", "_||_|_|_||__|");
            strTmp = strTmp.Replace("q", "_|_|_|_||__||");
            strTmp = strTmp.Replace("s", "_|_||_|_||__|");
            strTmp = strTmp.Replace("t", "_|_|_||_||__|");
            strTmp = strTmp.Replace("u", "_||__|_|_|_||");
            strTmp = strTmp.Replace("v", "_|__||_|_|_||");
            strTmp = strTmp.Replace("w", "_||__||_|_|_|");
            strTmp = strTmp.Replace("x", "_|__|_||_|_||");
            strTmp = strTmp.Replace("y", "_||__|_||_|_|");
            strTmp = strTmp.Replace("z", "_|__||_||_|_|");
            strTmp = strTmp.Replace("-", "_|__|_|_||_||");
            strTmp = strTmp.Replace("*", "_|__|_||_||_|");
            strTmp = strTmp.Replace("/", "_|__|__|_|__|");
            strTmp = strTmp.Replace("%", "_|_|__|__|__|");
            strTmp = strTmp.Replace("+", "_|__|_|__|__|");
            strTmp = strTmp.Replace(".", "_||__|_|_||_|");
            strTmp = strTmp.Replace("_", "<span style='height:" + height + ";width:" + width + ";background:#FFFFFF;'></span>");
            strTmp = strTmp.Replace("|", "<span style='height:" + height + ";width:" + width + ";background:#000000;'></span>");
            if (type_code == 1)
            {
                return strTmp + "<BR>" + code;
            }
            else
            {
                return strTmp;
            }
        }
