这篇文章重要引见了C#考证身份证号码准确性的实例代码，包含18位号码和15位号码的校验,须要的朋侪能够参考下

今天在QQ空间看到一篇关于C#言语考证18位身份证号码的考证要领和实例代码，抽了些时候进修了一下，个人以为还不错，所以把它记了下来，轻易今后运用！

18位号码：

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;//准确
    }

15位号码：

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;//准确
    }
