假设您的模式比这些数字更通用：

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();
}
