本文实例报告了C#经常使用正则考证函数。分享给人人供人人参考,细致以下:
1、Ip地点考证
/// <summary> /// Ip地点考证 /// </summary> public static bool CheckIp(string ip) { bool result = false; Regex ipReg = new Regex(@"^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\. (\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])$"); if (ipReg.IsMatch(ip)) { result = true; } return result; }
2、价钱考证
/// <summary> /// 价钱考证 /// </summary> /// <param name="priceStr"></param> /// <returns></returns> public bool CheckPrice(string priceStr) { bool result = false; Regex regex = new Regex(@"^\d+(\.\d{1,2})?$", RegexOptions.IgnoreCase); Match match = regex.Match(priceStr); if (match.Success) { result = true; } return result; }
3、正整数考证
/// <summary> /// 正整数考证 /// </summary> public static bool CheckPositiveInteger(string numStr) { bool result = false; Regex regex = new Regex(@"^[1-9]\d*$", RegexOptions.IgnoreCase); Match match = regex.Match(numStr); if (match.Success) { result = true; } return result; }
