c# - Star - 使用正则表达式在字符串中查找字符 *

Question

我试图在我的字符串中找到以下文本:'***'问题是 C# Regex 机制不允许我执行以下操作:

new Regex("***", RegexOptions.CultureInvariant | RegexOptions.Compiled);

由于

ArgumentException: "parsing "*" - Quantifier {x,y} following nothing."

显然它认为我的星星代表正则表达式，有没有办法告诉 Regex 机制将星星视为星星而不是其他任何东西？

Answer 1

* 在 Regex 中表示:

Matches the previous element zero or more times.

因此，您需要使用 \* 或 [*] 代替。

解释:

\

When followed by a character that is not recognized as an escaped character in this and other tables in this topic, matches that character. For example, \* is the same as \x2A.

[ character_group ]

Matches any single character in character_group.
