如何执行Regex.Replace时使用的命名组()

问题描述:

如何执行Regex.Replace当我使用一个名为捕获?到目前为止,我已经得到了这一点,它不会是我想要的东西,但不是在路上,我希望它:

How do I use named captures when performing Regex.Replace? I have gotten this far and it does what I want but not in the way I want it:

[TestCase("First Second", "Second First")]
public void NumberedReplaceTest(string input, string expected)
{
    Regex regex = new Regex("(?<firstMatch>First) (?<secondMatch>Second)");
    Assert.IsTrue(regex.IsMatch(input));
    string replace = regex.Replace(input, "$2 $1");
    Assert.AreEqual(expected, replace);
}



我想这两个词与名为捕获匹配,然后使用(命名)进行更换时捕获。

I want to match the two words with named captures and then use the (named) captures when performing the replace.

而不是$ 2 $ 1的 >,您可以用$ {secondMatch} $ {firstMatch}

Instead of "$2 $1", you can use "${secondMatch} ${firstMatch}".

有是所有的列表在更换你可以在这里做

There is a list of all the replacements you can do here.

下面是一个简短的列表:

Here is an abbreviated list:

$号 - 捕获的组由数

$number - The captured group by number.

$ {name}的 - 由名被俘组

$ - $文字。

$$ - $ literal.

$&放大器; - 整场比赛

$` - 在比赛前输入字符串

$` - The input string before the match.

$' - The input string after the match.

$ + - 拍摄的最后一组
