寻找“$ {sometext}”的正则表达式

Question

我发现使用这个 "\\${(.*?)\\}。

所以，我想： new Regex(@"\\$\\${(.*?)\\}");

但这似乎并不在这里工作，什么问题呢？

Answer 1

我会用new Regex(@"\${(.*?)}");

我们来分析一下你：

(@"\\$\\${(.*?)\\}"); 
    ^^^^^^  ^^^ 
    ||||||  |||-- 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.
