string empCode="";//一个ASCII码
           string hex = empCode.Substring(0,2);

                int value = Convert.ToInt32(hex, 16);
          // string stringValue = Char.ConvertFromUtf32(value);
               char charValue = (char)value;

             empCode = empCode.Substring(2, empCode.Length - 2);
              MatchCollection matchs = new Regex(@"3(\d)", RegexOptions.Singleline).Matches(empCode);
              if (matchs.Count != 0)
              {
                  foreach (Match match in matchs)
                   {
                       resultValue += match.Groups[1].Value;
                   }
               }
           
               empCode = charValue + resultValue;

补充一下：jsonstr是16进制的数据，

    for (int i = 0; i < jsonStr.Length / 2; i++)
            {
                string hex = jsonStr.Substring(2*i, 2);


                int value = Convert.ToInt32(hex, 16);
                char charValue = (char)value;
                //c[i] = charValue;
                empCode += charValue;

            }
