这是一个小示例应用程序,展示了如何解析日期。如果你知道格式,它也可以很容易地自定义来解析时间

static void Main(string[] args)
        {
            string source = "HTTP test [17] 20110515150601.log";
            Regex regex = new Regex(@"(d{8})d*.log");
            var match = regex.Match(source);
            if (match.Success)
            {
                DateTime date;
                if (DateTime.TryParseExact(match.Groups[1].Value, "yyyyMMdd", CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
                {
                    Console.WriteLine("Parsed date to {0}", date);
                }
                else
                {
                    Console.WriteLine("Could not parse date");
                }
            }
            else
            {
                Console.WriteLine("The input is not a match.");
            }
            Console.ReadLine();
        }
