构建正则表达式以搜索带下划线的文本 [英] build a regex to search underlined text

问题描述

我在实施某种技术时遇到麻烦-在带下划线的Richtextbox控件中选择下一个文本.

您会看到iam试图做一个文字处理器，但被卡住了.我已经能够按F1编写代码来逐个选择每个单词.现在，我只选择带下划线但可以是短语而不是单个单词的那些单词.

例如:hello codeproject.com-这是一个每个人都很好的网站每个人

想象我的光标在开始之前(打招呼之前)，然后按F1键(或任何按钮)，我想选择这是一个"，然后在下一个按键上单击站点为".但是我无法为此要求构建正则表达式或实现简单的逻辑.

有什么帮助吗? (任何语言都可以-vb.net/C#)

Iam having a trouble implementing a certain technique - selecting next text in a richtextbox control which is underlined.

You see iam trying to make a word processor but am stuck. I have been able to write the code to select each word one-by-one on pressing F1. Now i want to select only those words which are underlined but can be a phrase rather than single word.

Eg: hello codeproject.com - this is a nice site for everyone

imagine my cursor is at beginning (before hello) and i press F1 (or any button) I want to select "this is a" and on next keypress "site for". But iam not being able to build a regex or implement simple logic for this requirement.

Any help plz? (Any language will do -vb.net / C#)

推荐答案

通过以下方式运行myRichTextBox.Rtf:

Run myRichTextBox.Rtf through this:

//  using System.Text.RegularExpressions;
public static Regex regex = new Regex("(?<=\\\\\\\\ul).*(?=\\\\\\\\ulnone)",
    RegexOptions.IgnoreCase
    | RegexOptions.Multiline
    | RegexOptions.CultureInvariant
    | RegexOptions.IgnorePatternWhitespace
    | RegexOptions.Compiled
    );
