簡單的regex需要

Question

我有文本文件

01:02:39.952 MC:My text with several lines 
01:02:39.952 

我如何能趕上01:02:39.952 MC:和01:02:39.952

我在這個模式我的文本文件有很多像這樣的行之間的所有文字，我想抓住他們所有人。

假設你的模式是不是正是這些數字比較一般：

Regex regexObj = new Regex(
    @" 
    (?<= # Assert that the following can be matched before the current position: 
    \b       # start of ""word"" 
    \d{2}:\d{2}:\d{2}\.\d{3} # nn:nn:nn.nnn 
    \sMC:      # <space>MC: 
    )  # End of lookbehind assertion 
    .*? # Match any number of characters (as few as possible)... 
    (?= # ...until the following can be matched after the current position: 
    \b       # start of word 
    \d{2}:\d{2}:\d{2}\.\d{3} # nn:nn:nn.nnn 
    \b       # end of word 
    )  # End of lookahead assertion", 
    RegexOptions.Singleline | RegexOptions.IgnorePatternWhitespace); 
Match matchResult = regexObj.Match(subjectString); 
while (matchResult.Success) { 
    resultList.Add(matchResult.Value); 
    matchResult = matchResult.NextMatch(); 
}
