Unicode互相轉換方法

C#字串與Unicode互相轉換方法和代碼：

/// <summary>
        /// 將原始字串轉換為unicode,格式為\u....\u....
        /// </summary>
        /// <param name="srcText"></param>
        /// <returns></returns>
        private string StringToUnicode(string srcText)
        {
            string dst = "";
            char[] src = srcText.ToCharArray();
            for (int i = 0; i < src.Length; i++)
            {
                byte[] bytes = Encoding.Unicode.GetBytes(src[i].ToString());
                string str = @"\u" + bytes[1].ToString("X2") + bytes[0].ToString("X2");
                dst += str;
            }
            return dst;
        }

        /// <summary>
        /// 將Unicode字串\u....\u....格式字串轉換為原始字串
        /// </summary>
        /// <param name="srcText"></param>

        private string UnicodeToString(string srcText)
        {
            string dst = "";
            string src = srcText;
            int len = srcText.Length / 6;
           
            for (int i = 0; i <= len - 1; i++)
            {
                string str = "";
                str = src.Substring(0, 6).Substring(2);
                src = src.Substring(6);
                byte[] bytes = new byte[2];
                bytes[1] = byte.Parse(int.Parse(str.Substring(0, 2), NumberStyles.HexNumber).ToString());
                bytes[0] = byte.Parse(int.Parse(str.Substring(2, 2), NumberStyles.HexNumber).ToString());
                dst += Encoding.Unicode.GetString(bytes);
            }
            return dst;
        }
