[英]C#/regex, simple question
How comes this writes False? 这怎么写错?
Console.Write(Regex.IsMatch("[abcde]{1,16}", "babe"));
What's wrong with my regex? 我的正则表达式有什么问题? Doesn't that regex roughly translate to: contains between 1 and 16 characters, a through e?
该正则表达式是否大致翻译为:包含1到16个字符,从a到e?
Your arguments are switched. 您的论点已切换。 Ie, use:
即,使用:
Regex.IsMatch("babe", "[abcde]{1,16}")
instead, 代替,
That's going to match any of the characters in "babe" that fall between a and e. 这将匹配“婴儿”中介于a和e之间的任何字符。 So for example, "babez" would match as "babe".
因此,例如,“ babez”将匹配为“ babe”。 I get the sense you want treat it as a string match.
我知道您想将其视为字符串匹配。 Try:
尝试:
[a-e]{1,16}$
