ここで私が使用している正規表現コード

var data = new Regex(@"^DateTime:\ (?<StartTime>[^\r]+)\r\nCommand: ALTER INDEX\ (?<Command>[^\r]+)\r\nComment:\ (?<Comment>[^\r]+)\r\nOutcome:\ (?<Outcome>[^\r]+)\r\nDuration:\ (?<Duration>[^\r]+)\r\nDateTime:\ (?<EndTime>[^\r]+)", RegexOptions.Multiline)
                .Matches(File.ReadAllText(@"C:\Users\dalvi\Desktop\Index Logs\trial.txt")).Cast<Match>().Select(m => new
                {
                    StartTime = m.Groups["StartTime"].Value,
                    Command = m.Groups["Command"].Value,
                    Comment = m.Groups["Comment"].Value,
                    Outcome = m.Groups["Outcome"].Value,
                    Duration = m.Groups["Duration"].Value,
                    EndTime = m.Groups["EndTime"].Value
                });

しかし、出力は Command: と Comment: の後にテキスト全体を取得していますが、ON の後のテキストは [FMC360Train_MSCRM].[MetadataSchema].[LocalizedLabel] を意味し、次のテキストは別の値として REORGANIZE になります。正規表現コードを変更するにはどうすればよいですかのような出力を得る

StartTime   DBTableName Type    Comment Outcome Duration    EndTime
2012-12-09 17:00:18 [FMC360Train_MSCRM].[MetadataSchema].[Attribute]    REORGANIZE  PageCount: 1336 Succeeded   00:00:01    2012-12-09 17:00:19

私のプログラムは長い出力を得るために働いていますが、上記の形式で出力したいので、正規表現についてのみ助けが必要です。

行を解析するための正確なルールはわかりませんCommandが、次の正規表現は 2 つの入力例で機能します。

var data = new Regex(@"^DateTime:\ (?<StartTime>[^\r]+)\r\nCommand: ALTER INDEX \[([^\]]+)\] ON (?<DBTableName>\[([^\]]+)\]\.\[([^\]]+)\]\.\[([^\]]+)\]) (?<Type>[^ ]+) ([^\r]+)\r\nComment:\ (?<Comment>.+Fragmentation: (?<Fragmentation>[\d\.]+)[^\r]+)\r\nOutcome:\ (?<Outcome>[^\r]+)\r\nDuration:\ (?<Duration>[^\r]+)\r\nDateTime:\ (?<EndTime>[^\r]+)", RegexOptions.Multiline)
    .Matches(File.ReadAllText(@"C:\Users\dalvi\Desktop\Index Logs\trial.txt")).Cast<Match>().Select(m => new
        {
            StartTime = m.Groups["StartTime"].Value,
            DBTableName = m.Groups["DBTableName"].Value,
            Type = m.Groups["Type"].Value,
            Comment = m.Groups["Comment"].Value,
            Fragmentation = m.Groups["Fragmentation"].Value,
            Outcome = m.Groups["Outcome"].Value,
            Duration = m.Groups["Duration"].Value,
            EndTime = m.Groups["EndTime"].Value
        });

        var data = new Regex(@"^DateTime:\ (?<StartTime>[^\r]+)\r\nCommand: ALTER INDEX \[([^\]]+)\] ON (?<DBTableName>\[([^\]]+)\]\.\[([^\]]+)\]\.\[([^\]]+)\]) (?<Type>[^ ]+) ([^\r]+)\r\nComment:\ (?<Comment>.+Fragmentation: (?<Fragmentation>[\d\.]+)[^\r]+)\r\nOutcome:\ (?<Outcome>[^\r]+)\r\nDuration:\ (?<Duration>[^\r]+)\r\nDateTime:\ (?<EndTime>[^\r]+)", RegexOptions.Multiline)

        foreach (var datum in data)
        {

        Console.ReadKey();
