C#正则表达式匹配字符串(C# regex to match string)
我目前在使用正则表达式匹配字符串时遇到了困难。 目标是匹配:
一两个字母 一个,两个或三个数字 零或一个星号如U21,F305和H12 *。 我正在使用的正则表达式是:
\D{1,2}\d{1,3}\*?但是,它一直在匹配字符串:
3.0L 6HBW20 3/8" Y1015我对正则表达式并不是太明亮,但是这让我无法完成我的项目。 谁能帮我吗?
谢谢。

3.0L 6HBW20 3/8" Y1015I'm not too bright with regex, but this is holding me from completing my project. Can anyone help me out?

\D匹配任何非数字,这是一个比字母大得多的集合(基本上所有其他东西 ,包括句号,斜杠等)。 尝试使用[a-zA-Z]{1,2}匹配1或2个字母。
[a-zA-Z]{1,2}\d{1,3}\*?\D matches any non-digit, which is a much larger set than just letters (basically everything else, including periods, slashes, etc). Try using [a-zA-Z]{1,2} to match 1 or 2 letters.
[a-zA-Z]{1,2}\d{1,3}\*?更多推荐
