这里最好的方法是将日志文件之间存储的信息和日志文件中的数据作为一些问题来获取所有时间实例？我在日志中有很多回报，我需要抓住所有这些。
我想用indexof字符串函数做这件事，但它太复杂了。 也许在这里使用正则表达式是个好主意？ （问题我对正则表达式一无所知）
答案 0 :(得分：2)
你可以这样做：
static readonly Regex DataContainerRegex =
new Regex(@"^(\d\d:\d\d:\d\d\.\d\d\d) MC: (<DataContainer>.*?</DataContainer>)",
RegexOptions.Singleline | RegexOptions.Multiline);
static IEnumerable<Tuple<DateTime, XDocument>> Parse(string data)
{
var matches = DataContainerRegex.Matches(data);
return from Match match in matches
let date = DateTime.Parse(match.Groups[1].Value,
CultureInfo.InvariantCulture)
let doc = XDocument.Parse(match.Groups[2].Value)
select Tuple.Create(date, doc);
}
如果您真的想要<DataContainer>而不是XDocument之间的文字，只需将括号直接放在.*?周围并解析第二组。
答案 1 :(得分：0)
这是我尝试解析示例日志文件：
static IEnumerable<Tuple<DateTime, string>> GetLogEntries(string path)
{
var regex = new Regex(@"^(\d{2}\:\d{2}\:\d{2}\.\d{3}\s)(.*)", RegexOptions.Compiled);
var logLineBuilder = new StringBuilder();
Match currentMatch = null;
foreach(var line in File.ReadLines(path))
{
var match = regex.Match(line);
if (match.Success && logLineBuilder.Length != 0)
{
yield return Tuple.Create(DateTime.Parse(currentMatch.Groups[1].Value), logLineBuilder.ToString());
logLineBuilder.Clear();
}
if (match.Success)
currentMatch = match;
logLineBuilder.AppendLine(match.Success ? match.Groups[2].Value : line);
}
yield return Tuple.Create(DateTime.Parse(currentMatch.Groups[1].Value), logLineBuilder.ToString());
}
我认为日志文件可能很大，所以我使用了File.ReadLines，它会一次读取一行日志文件。这样可以减少内存占用，因为它不必将整个文件读入内存。这可能是特别大的日志文件的问题。然后，您应该能够使用LINQ表达式过滤任何其他条件，例如：
var entries = GetLogEntries("logfile.txt");
var dataContainers = from e in entries
where e.Item2.IndexOf("MC: <DataContainer>") != -1
select XDocument.Parse(e.Item2.Substring(3));
Console.WriteLine(dataContainers.Count()); //prints "2"
