Question

如何仅捕获以下部分内容。捕获应限制在M / S和UniqueID之间。我的正则表达式(?<=M\/S\s)((\w+)?\s)+(?=(U|$))使用UniqueID捕获行，但不捕获没有UniqueId的行。有人可以指导我吗？

我认为您需要这样的代码（使用LinQ）：

var list = new[]
{
    "$0117578$ $0003123$ ADECBR5148K M/S R A MARKETING PRIVATE LIMITED",
    "$0117942$ $0003487$ ADECBR6540D M/S RICHDAUGHTER KURIES AND INVESTMENTS PVT LIMITED",
    "$0117856$ $0003401$ ADEBCR7789P M/S REGENT TRADING CO",
    "$0117881$ $0003426$ ADEBCR1123M M/S RELIANT MARKETING AND SERVICES PVT LTD  U53599KL1989PTC000007",
    "$0117896$ $0003441$ ADECBR7750D M/S GANDHIMARG CHITTIES PRIVATE LIMITED U64992KL2003PTC016359",
    "$0117923$ $0003468$ ADEECR0117J M/S REVELATION AUTOMATIC PISTOLS PRIVATE LIMITED U29300KL2011PTC020087",
    "$0117927$ $0003472$ ADECBR9145C M/S RESSEA DOMESTIC APPLE PRIVATE LIMITED U29208KL2004PTC010016",
    "$0117746$ $0003291$ ADEGCR4072G M/S RANDOR MARITIME INC"
};

// Here I use named groups to capture what I want as `A`
// Format of UniqueId here is : `U[A-Z\d]{20}`
var regex = new Regex(@"(M\/S(?<A>.+)U[A-Z\d]{20})|(M\/S(?<A>.+)$)");
var matches = (from str in list                   // loop over `list` as `str`
    select regex.Match(str)                       // create new list of values from `str`
    into match                                    // into a new variable as `match`
    where match.Groups.Count > 1                  // filter new list by `match`
    select match.Groups["A"].ToString().TrimEnd() //create new list of values again
    ).ToList();

如何捕获M / S之间但没有最后一个唯一ID的单词
