正則表達式以獲取以下模式

Question

嗨，我有以下代碼行

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

我需要知道正則表達式模式，該模式可以為我找到上述模式，其中字符串從{開始，然后是一些文本，然后是諸如“ hello”和}之類的關鍵字。

請幫忙

所以我有

function test(a,b,c){
}

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

我得到了這個表達式function\\s+(\\S+)\\s*\\((.|\\n)*?\\)\\s*{

這給了我function test(a,b,c)和

function test2(c,a,d)

我想要一個正則表達式，當它在該函數中找到諸如“ test”之類的關鍵字時，該函數可以為我提供功能。

說得通？

Answer 1

我不知道C＃，但喜歡（與.匹配換行符）的正則表達式：

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

應該做的工作。

說明：

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

(?s-imx:                 group, but do not capture (with . matching

                         normally) (matching whitespace and #

這個怎么樣：

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