c# - 拆分然后逐步连接字符串 - C# Linq

Question

这是我的字符串:

www.stackoverflow.com/questions/ask/user/end

我用 / 把它拆分成一个单独的单词列表:myString.Split('/').ToList()

输出:

www.stackoverflow.com
questions
ask
user
end

我需要重新加入字符串以获得这样的列表:

www.stackoverflow.com
www.stackoverflow.com/questions
www.stackoverflow.com/questions/ask
www.stackoverflow.com/questions/ask/user
www.stackoverflow.com/questions/ask/user/end

我考虑过 linq aggregate 但它似乎不适合这里。我想通过 linq 来完成这一切

Answer 1

您可以尝试使用 foreach 对其进行迭代

var splitted = "www.stackoverflow.com/questions/ask/user/end".Split('/').ToList();
string full = "";
foreach (var part in splitted)
{
    full=$"{full}/{part}"
    Console.Write(full);
}

或者使用 linq:

var splitted = "www.stackoverflow.com/questions/ask/user/end".Split('/').ToList();
var list = splitted.Select((x, i) => string.Join("/", a.Take(i + 1)));
