在正则表达式C中匹配{{string}} [英] matching {{string}} in regex c#

问题描述

与

{{string}}

结果应为 string .

我是否必须同时使用大括号?

Do I have to escape both curly brackets?

推荐答案

不，实际上以下内容应该可以正常工作:

No, actually the following should work just fine:

"{{([^}]*)}}"

修改:正如 dtb 所指出的，以上表达式对于双括号中包含单个} 的字符串失败.为了处理这种情况，以下示例将做得更好:

As pointed out by dtb the expression above fails for a string containing a single } within the double brackets. To handle this case the following example would do a much better job:

"{{((?:}(?!})|[^}])*)}}"

但是，最简单的解决方案可能是:

Edit 2: The simplest solution however would probably be the following:

"{{(.*?)}}"
