c# 实现获取汉字十六进制Unicode编码字符串

1、  汉字转十六进制UNICODE编码字符串

/// <summary>
        /// ////
        /// </summary>
        /// <param name="character"></param>
        /// <returns></returns>
        public string CharacterToCoding(string character)
        {
            string coding = "";

for (int i = 0; i < character.Length; i++)
            {
                byte[] bytes = System.Text.Encoding.Unicode.GetBytes(character.Substring(i, 1));

//取出二进制编码内容  
                string lowCode = System.Convert.ToString(bytes[0], 16);

//取出低字节编码内容（两位16进制）  
                if (lowCode.Length == 1)
                {
                    lowCode = "0" + lowCode;
                }

string hightCode = System.Convert.ToString(bytes[1], 16);

//取出高字节编码内容（两位16进制）  
                if (hightCode.Length == 1)
                {
                    hightCode = "0" + hightCode;
                }

coding += (hightCode + lowCode);

}

return coding;
        }

2、  十六进制UNICODE编码字符串 转 汉字

/// <summary>
        /// //
        /// </summary>
        /// <param name="text"></param>
        /// <returns></returns>
        public string UnicodeToCharacter(string text)
        {
            byte[] arr = HexStringToByteArray(text);

System.Text.UnicodeEncoding converter = new System.Text.UnicodeEncoding();

string str = converter.GetString(arr);

return str;
        }
