C#中文和UNICODE字符转换方法

//可以包括其他字符 public string uncode(string str) { string outStr = ""; Regex reg = new Regex(@"(?i)//u([0-9a-f]{4})"); outStr = reg.Replace(str, delegate(Match m1) { return ((char)Convert.ToInt32(m1.Groups[1].Value, 16)).ToString(); }); return outStr; } //中文转为UNICODE字符 string str = "中文"; string outStr = ""; if (!string.IsNullOrEmpty(str)) { for (int i = 0; i < str.Length; i++) { //将中文字符转为10进制整数，然后转为16进制unicode字符 outStr += "//u" + ((int)str[i]).ToString("x"); } } //UNICODE字符转为中文 string str = "//u4e2d//u6587"; string outStr = ""; if (!string.IsNullOrEmpty(str)) { string[] strlist = str.Replace("//","").Split('u'); try { for (int i = 1; i < strlist.Length; i++) { //将unicode字符转为10进制整数，然后转为char中文字符 outStr += (char)int.Parse(strlist[i], System.Globalization.NumberStyles.HexNumber); } } catch (FormatException ex) { outStr = ex.Message; } }
