寻找“$ {sometext}”的正则表达式

Question

我发现了这个 "\\${(.*?)\\}。

所以我试过了： new Regex(@"\\$\\${(.*?)\\}");

但这似乎不起作用，这里的问题是什么？

Answer 1

我会使用new Regex(@"\${(.*?)}");

让我们分析一下：

(@"\\$\\${(.*?)\\}");
   ^^^^^^      ^^^
   ||||||      |||-- Your don't need to double your slashes in a literal string.
     \  |        |       
      \ |        |
       \|--------|-- You have 2 "$" and you just want one
                 |
                 |-- You don't need to escape "{" since it doesn't enclose digits
                     and can't be interpreted as a length attribute.
