是否有定期的EX pression返回相同的字符重复的比赛？ [英] Is there a regular expression to return a match of a repetition of the same characters?

问题描述

使用.NET正EX pressions。

Using .NET regular expressions.

让我们说我有以下文字：

Let's say I have the following text:

ddddddddddd

ddddddddddd

和我想测试超过2的重复的任意字符。

And I would like to test for a repetition of more than 2 for any character.

正则表达式不应返回匹配含双字母之类的词的文本的看的。

The regex should not return a match for a text containing double letters like the word "look".

不要假定输入文本只包含字母D的重复。 我想任何字符的重复。

Do not assume the input text only consists of repetition of the letter d. I want ANY repetition of characters.

推荐答案

试试这个

(.)\1{2,}

请参阅它这里Regexr

在。匹配任何字符，这个字符存储，因为它周围的支架1组。该 \ 1 {2} 检查，然后进行2个或更多这个人物（与原来相匹配的字符，然后3个或更多在一起。）

The . matches any character, this character is stored in group 1, because of the brackets around it. The \1{2,} checks then for 2 or more of this character (together with the originally matched character then 3 or more.)
