C# 实现数据脱敏

数据脱敏，此处以姓名、身份证为例
 /// <summary>
        /// 姓名敏感处理
        /// </summary>
        /// <param name="fullName">姓名</param>
        /// <returns>脱敏后的姓名</returns>
        public string SetSensitiveNamestring fullName)
        {
            if string.IsNullOrEmptyfullName)) return string.Empty;

            string familyName = fullName.Substring0, 1);
            string end = fullName.SubstringfullName.Length - 1, 1);
            string name = string.Empty;
            //长度为2
            if fullName.Length <= 2) name = familyName + "*";
            //长度大于2
            else if fullName.Length >= 3)
            {
                name = familyName.PadRightfullName.Length - 1, '*') + end;
            }
            return name;
        }

        /// <summary>
        /// 身份证脱敏
        /// </summary>
        /// <param name="idCardNo">身份证号</param>
        /// <returns>脱敏后的身份证号</returns>
        private string SetSensitiveIdCardNostring idCardNo)
        {
            if string.IsNullOrEmptyidCardNo)
                || idCardNo.Length != 15 && idCardNo.Length != 18)) return idCardNo;

            string begin = idCardNo.Substring0, 6);
            string middle = idCardNo.Substring6, 8);
            string end = idCardNo.Substring14, idCardNo.Length - 14);

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

测试：
            string no = SetSensitiveIdCardNo"610253199804230067");
            //string no = SetSensitiveIdCardNo"610253199804230");
            string name = SetSensitiveName"齐天大圣孙悟空");
            MessageBox.Show"idcardno==" + no + "
name==" + name);
