方法三

public string FromUnicodeString(string str, string SplitString = "u")
         {

            string reString = str;
            System.Text.RegularExpressions.Regex reg = new System.Text.RegularExpressions.Regex(regexCode);
            System.Text.RegularExpressions.MatchCollection mc = reg.Matches(reString);
            for (int i = 0; i
