在这里，什么是最好的方法来获得所有的时间实例，以及存储在日志文件和数据之间的信息作为一些元组?我在日志中有很多返回，我需要捕获它们。

我想用indexof字符串函数来做，但它太复杂了。也许在这里使用正则表达式是个好主意?(这个问题我没有关于正则表达式的线索)

从日志文件中获取所需信息的最佳方式

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之间的文本，只需将括号直接放在.*?周围并解析第二组

下面是我解析示例日志文件的尝试:

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将一次一行地读取日志文件。这将降低内存占用，因为它不必将整个文件读取到内存中。对于特别大的日志文件，这可能是一个问题。然后，您应该能够使用LINQ表达式过滤任何附加条件，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"
