C# 實現數據脫敏

數據脫敏，此處以姓名、身份證為例
 /// <summary>
        /// 姓名敏感處理
        /// </summary>
        /// <param name="fullName">姓名</param>
        /// <returns>脫敏后的姓名</returns>
        public string SetSensitiveName(string fullName)
        {
            if (string.IsNullOrEmpty(fullName)) return string.Empty;

            string familyName = fullName.Substring(0, 1);
            string end = fullName.Substring(fullName.Length - 1, 1);
            string name = string.Empty;
            //長度為2
            if (fullName.Length <= 2) name = familyName + "*";
            //長度大於2
            else if (fullName.Length >= 3)
            {
                name = familyName.PadRight(fullName.Length - 1, '*') + end;
            }
            return name;
        }

        /// <summary>
        /// 身份證脫敏
        /// </summary>
        /// <param name="idCardNo">身份證號</param>
        /// <returns>脫敏后的身份證號</returns>
        private string SetSensitiveIdCardNo(string idCardNo)
        {
            if (string.IsNullOrEmpty(idCardNo)
                || (idCardNo.Length != 15 && idCardNo.Length != 18)) return idCardNo;

            string begin = idCardNo.Substring(0, 6);
            string middle = idCardNo.Substring(6, 8);
            string end = idCardNo.Substring(14, idCardNo.Length - 14);

            string card = string.Empty;
            card = begin + "********" + end;
            return card;
        }

測試：
            string no = SetSensitiveIdCardNo("610253199804230067");
            //string no = SetSensitiveIdCardNo("610253199804230");
            string name = SetSensitiveName("齊天大聖孫悟空");
            MessageBox.Show("idcardno==" + no + "\r\nname==" + name);
