Hello guys

I want to cut out a part of a path but don't know how.
To get the path, I use this code:

C#

String path = System.IO.Path.GetDirectoryName(fullyQualifiedName);

(path = "Y:\\Test\\Project\\bin\\Debug")

Now I need the first part without "\\bin\\Debug".
How can I cut this part out of the current path?

I'm thankful for all answers.

Greetings

Why "MFC"? What prevents you from just reading the documentation?

Pick a programming language first. The answers you get are probably going to be vastly different. But for either one you chose, using a combination of SubString and IndexOf will probably do the trick.

It's C#, "MFC" could be a slip of a hand. :-)

You don't mention whether you want it in C++ or C#. But your coding pattern seems me it is in C#. Another question,is your above path static?
If so then you can do it within only 3 lines.

C#

String path= @"Y:\\Test\\Project\\bin\\Debug";
String[] extract = Regex.Split(path,"bin");  //split it in bin
String main = extract[0].TrimEnd('\\'); //extract[0] is Y:\\Test\\Project\\ ,so exclude \\ here
Console.WriteLine("Main Path: "+main);//get main path

You cannot modify any string; strings are immutable, so all string methods changing the string actually create a new string object. You can use this one: http://msdn.microsoft.com/en-us/library/fk49wtc1.aspx[^].

Thank you, Maciej.

Hi . i think the simplest way is :

string s=path.Substring(path.IndexOf('Y'),15);

in this line of code you get a substring by position of 'Y' character.
and the count of forwarding to get substring, is 15 character.
i hope this help you.
Good luck

Solution 2

Your tags are a bit puzzling since you tagged C# and MFC, which don't play well together. The answers you have so far are related to C#. If you are using MFC, that means C++, and you can use _splitpath()/_wsplitpath()[^] and then either std::string[^] or CString[^] to extract or replace parts of the path.

CString works with ANSI or Unicode, std::string is ANSI only. Both have their own vocal self righteous religious lobbies.

It's a good point, even though the question is apparently on .NET, 5ed.
(Ha, someone decided to down-vote both answers. Funny :-)
