尋找「$ {sometext}」的正則表達式

Question

我發現使用這個 "\\${(.*?)\\}。

所以，我想： new Regex(@"\\$\\${(.*?)\\}");

但這似乎並不在這裏工作，什麼問題呢？

Answer 1

我會用new Regex(@"\${(.*?)}");

我們來分析一下你：

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