正则表达式是什么? [英] What is the RegEx for this?

问题描述

我有各种各样的字符串，它们可能包含也可能不包含(_#)"，其中#"是一个数字(也可以是多个数字.

请注意，有时它不存在(整个序列)，但如果存在，则总是在开头.我想删除它以用于显示目的(如果存在)，因此我认为RegEx可以轻松做到这一点(我知道它确实可以)，但是我很生锈.

这是一些字符串示例

I have various strings that may or may not contain ''(_#)'' where ''#'' is a number (can be multiple digits also.

Note sometimes it does not exist (the whole sequence), but if it does it is always at the beginning. I want to remove it for display purposes if it exists, so I thought RegEx would do this easily (well I know it does), but I am quite rusty.

Here are some string examples

(_0) Welcome
(_1) Information
(_2) Products
(_3) Help
Contact Info
Maps
Celery
Wild Wings
Deep Fried Pickles
(_4) Your thinking about BWW now

因此所有这些字符串都以某个变量s结尾，我想删除(_#)"(如果存在)并将该字符串存储在display中.

预先谢谢您.

So all of these strings end up in some variable s and I want to rip out the ''(_#)'' if it exists and store the string in display.

Thank you in advance.

推荐答案

尝试:

public static Regex regex = new Regex(
      @"^\(_\d*\)\s*",
    RegexOptions.IgnoreCase
    | RegexOptions.Multiline
    | RegexOptions.CultureInvariant
    | RegexOptions.IgnorePatternWhitespace
    | RegexOptions.Compiled
    );

string result = regex.Replace(InputText,"");

获取 Expresso [ ^ ]-它是免费的，它检查并生成正则表达式.一旦我测试了正则表达式，它就会生成代码！

Get a copy of Expresso [^] - it''s free, and it examines and generates Regular expressions. It generated the code once I had tested the regex!
