c# - 正则表达式获得以下模式

Question

嗨，我有以下代码行

{
.....(here i can have anything, numbers, string special characters
...."hello"
}

我需要知道为我找到上述模式的正则表达式模式，其中字符串从 { 开始，然后是一些文本，然后是像“hello”这样的关键字，然后是 }。

请帮忙

所以我有

function test(a,b,c){
}

function test2(c,a,d){
if(a > 0){
    alert('test');
}

我得到了这个表达function\s+(\S+)\s*\((.|\n)*?\)\s*{

这给了我function test(a,b,c)和

function test2(c,a,d)

我想要一个正则表达式，当它在该函数中找到像“test”这样的关键字时，它会给我函数。

说得通？

Answer 1

我不知道 c# 但正则表达式喜欢（带有.匹配的换行符）：

.*\bfunction\b.+?\bhello\b.+?\}

应该做的工作。

解释：

The regular expression:
(?s-imx:.*\bfunction\b.+?\bhello\b.+?\})
matches as follows:

这个怎么样：

MatchCollection matches = Regex.Matches(YourText, @"\{[^}]*""hello"".\}", RegexOptions.Multiline);
foreach (Match match in matches)
{
    foreach (Capture capture in match.Captures)
    {
    Console.WriteLine(capture.Value);
}
