Asp.Net中的字符串和HTML十进制编码转换实现代码_实用技巧_

 using System; using System.Text.RegularExpressions; public partial class purchase_property : System.Web.UI.Page { /// 
 /// Asp.Net将字符串转为16进制区码位&#编码 /// 
 /// 要进行16进制区码位编码的字符串 /// 编码后的16进制区码位&#字符串 public string StringToUnicodeCodeBit(string s) { if (string.IsNullOrEmpty(s) || s.Trim() == "") return ""; string r = ""; for (int i = 0; i < s.Length; i++) r += "&#" + ((int)s[i]).ToString() + ";"; return r; } public string reMatchEvaluator(Match m) { return ((char)int.Parse(m.Groups[1].Value)).ToString(); } /// 
 /// Asp.Net将16进制区码位&#编码转为对应的字符串 /// 
 /// 16进制区码位编码的字符串 /// 16进制区码位编码的字符串对应的字符串 public string UnicodeCodeBitToString(string s) { if (string.IsNullOrEmpty(s) || s.Trim() == "") return ""; Regex rx = new Regex(@"&#(\d+);", RegexOptions.Compiled); return rx.Replace(s, reMatchEvaluator); } protected void Page_Load(object sender, EventArgs e) { string s = "Asp.Net区码位字符串"; s = StringToUnicodeCodeBit(s);//转为&#编码 Response.Write(s); Response.Write("\n"); s = UnicodeCodeBitToString(s);//&#编码转为字符串 Response.Write(s); } }

 function uncode(str) {//把&#编码转换成字符 return str.replace(/&#(x)?([^&]{1,5});?/g, function (a, b, c) { return String.fromCharCode(parseInt(c, b ? 16 : 10)); }); } function encode(str) {//把字符转换成&#编码 var a = [], i = 0; for (; i < str.length; ) a[i] = str.charCodeAt(i++); return "&#" + a.join(";&#") + ";"; }
