C#關於驗證社會安全號碼碼的執行個體分析（正確性）

這篇文章主要介紹了C#驗證社會安全號碼碼正確性的執行個體代碼，包括18位號碼和15位號碼的校正,需要的朋友可以參考下

今天在QQ空間看到一篇關於C#語言驗證18位社會安全號碼碼的驗證方法和執行個體代碼，抽了些時間學習了一下，個人覺得還不錯，所以把它記了下來，方便以後使用！

18位號碼：

private static bool CheckIDCard18(string Id)    {      long n = 0;      if (long.TryParse(Id.Remove(17), out n) == false || n < Math.Pow(10, 16) || long.TryParse(Id.Replace('x', '0').Replace('X', '0'), out n) == false)      {        return false;      }      string address = "11x22x35x44x53x12x23x36x45x54x13x31x37x46x61x14x32x41x50x62x15x33x42x51x63x21x34x43x52x64x65x71x81x82x91";      if (address.IndexOf(Id.Remove(2)) == -1)      {        return false;      }      string birth = Id.Substring(6, 8).Insert(6, "-").Insert(4, "-");      DateTime time = new DateTime();      if (DateTime.TryParse(birth, out time) == false)      {        return false;      }      string[] arrVarifyCode = ("1,0,x,9,8,7,6,5,4,3,2").Split(',');      string[] Wi = ("7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2").Split(',');      char[] Ai = Id.Remove(17).ToCharArray();      int sum = 0;      for (int i = 0; i < 17; i++)      {        sum += int.Parse(Wi[i]) * int.Parse(Ai[i].ToString());      }      int y = -1;      Math.pRem(sum, 11, out y);      if (arrVarifyCode[y] != Id.Substring(17, 1).ToLower())      {        return false;      }      return true;//正確    }

15位號碼：

private static bool CheckIDCard15(string Id)    {      long n = 0;      if (long.TryParse(Id, out n) == false || n < Math.Pow(10, 14))      {        return false;      }      string address = "11x22x35x44x53x12x23x36x45x54x13x31x37x46x61x14x32x41x50x62x15x33x42x51x63x21x34x43x52x64x65x71x81x82x91";      if (address.IndexOf(Id.Remove(2)) == -1)      {        return false;      }      string birth = Id.Substring(6, 6).Insert(4, "-").Insert(2, "-");      DateTime time = new DateTime();      if (DateTime.TryParse(birth, out time) == false)      {        return false;      }      return true;//正確    }
