C#关于验证身份证号码的实例分析（正确性）

今天在QQ空间看到一篇关于C#语言验证18位身份证号码的验证方法和实例代码，抽了些时间学习了一下，个人觉得还不错，所以把它记了下来，方便以后使用！

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;//正确      }

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;//正确      }
