Split and then Joining the String step by step - C# Linq

Question

Here is my string:

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

I split it with / into a list of separated words:myString.Split('/').ToList()

Output:

www.stackoverflow.com
questions
ask
user
end

and I need to rejoin the string to get a list like this:

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

I think about linq aggregate but it seems it is not suitable here. I want to do this all through linq

Answer 1

You can try iterating over it with foreach

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

Or use linq:

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