這篇文章給大家分享的是有關(guān)C#如何驗(yàn)證身份證號(hào)碼的內(nèi)容。小編覺得挺實(shí)用的,因此分享給大家做個(gè)參考,一起跟隨小編過來看看吧。
18位號(hào)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(hào)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 }
