我的日志文件如下所示：

1）我需要获得这4个日志条目中的每一个所以从***开始从行开始并且每个下一行都不以***为开头 2）我需要包含一些关键字的日志条目（例如word＆＃34; AGPRSKeysAssocEnum＆＃34; - 第2个日志条目）
必须使用正则表达式模式完成。

Answer 1

 string text = fctb.Text;
 string strRegex = @"(\*\*\* (.*?)(?=\*\*\* |\z))";                      // ANSWER #1 
 //string strRegex = @"(\*\*\* [^\*]+AGPRSKeysAssocEnum.*?)(?=\*\*\*|\z)"; // ANSWER #2
 Regex myRegex = new Regex(strRegex, RegexOptions.Singleline);
 MatchCollection m = myRegex.Matches(text);
 foreach (Match sm in m)
 {
    System.Diagnostics.Debug.WriteLine(sm.Groups[1].Value);
    System.Diagnostics.Debug.WriteLine(new String('-', 100));
 }

或带有关键字的搜索条目首先拆分日志，然后将regex likethis应用于每个日志，例如：

string text = "Your log text"; IEnumerable<string> splittedLog = GetEntriesForLog(text); string strRegex = @".*?AGPRSKeysAssocEnum.*|\z"; Regex myRegex = new Regex(strRegex, RegexOptions.ExplicitCapture | RegexOptions.Singleline); var entries = splittedLog.Where(entry => myRegex.IsMatch(entry)).ToList();

如何匹配包含和不包含关键字的多行日志条目（正则表达式）
