学了一段时间的Web服务，今天利用网上的资源，做了一个15或18位身份证验证带输出省、市、区、生日、性别，主要是想练练手。现在把过程和心得分享给大家。

string[] strProvince = new string[] { null, null, null, null, null, null, null, null, null, null, null, "北京", "天津", "河北", "山西", "内蒙古", null, null, null, null, null, "辽宁", "吉林", "黑龙江", null, null, null, null, null, null, null, "上海", "江苏", "浙江", "安微", "福建", "江西", "山东", null, null, null, "河南", "湖北", "湖南", "广东", "广西", "海南", null, null, null, "重庆", "四川", "贵州", "云南", "西藏", null, null, null, null, null, null, "陕西", "甘肃", "青海", "宁夏", "新疆", null, null, null, null, null, "台湾", null, null, null, null, null, null, null, null, null, "香港", "澳门", null, null, null, null, null, null, null, null, "国外" }; double iSum = 0; idCardClass cardidData = new idCardClass(); System.Text.RegularExpressions.Regex rg = new System.Text.RegularExpressions.Regex(@"^\d{17}(\d|x)$|^\d{15}$"); System.Text.RegularExpressions.Match mc = rg.Match(cardid); if (!mc.Success) { cardidData.isValid = false; cardidData.chkInfo = "不是有效的身份证号"; return cardidData;
} if (cardid.Length == 15) { cardid = this.convert15to18(cardid); cardid = cardid.ToLower(); cardid = cardid.Replace("x", "a"); } if (strProvince[int.Parse(cardid.Substring(0, 2))] == null) { cardidData.isValid = false; cardidData.chkInfo = "非法地区"; return cardidData; } try { DateTime.Parse(cardid.Substring(6, 4) + "-" + cardid.Substring(10, 2) + "-" + cardid.Substring(12, 2)); } catch { cardidData.isValid = false; cardidData.chkInfo = "非法生日"; return cardidData; } for (int i = 17; i >= 0; i--) { iSum += (System.Math.Pow(2, i) % 11) * int.Parse(cardid[17 - i].ToString(), System.Globalization.NumberStyles.HexNumber); } if (iSum % 11 != 1) { cardidData.isValid = false; cardidData.chkInfo = "非法证号"; return cardidData; } cardidData.isValid = true; cardidData.chkInfo = strProvince[int.Parse(cardid.Substring(0, 2))] + "," + cardid.Substring(6, 4) + "年" + cardid.Substring(10, 2) + "月" + cardid.Substring(12, 2) + "日," + (int.Parse(cardid.Substring(16, 1)) % 2 == 1 ?

下面这个效果是我原来的带输出省、市、区的身份证号Web服务，但想想有点漏洞，而且他关联数据库，所以也就没发这个，上面的代码是有点啰嗦，园子里有人写过新的验证15位、18位的身份证号验证，大家可以去搜搜，不过他好像不能输出省。
