How can I get the last folder from a path string?

Question

I have a directory that looks something like this:

C:\\Users\\me\\Projects\\

In my application, I append to that path a given project name:

Answer 1

string path = @"C:\Users\me\Projects\myProject";
string result = System.IO.Path.GetFileName(path);

result = myProject

Answer 2

If you're a Linq addict like me, you may enjoy this. Works regardless of the termination of the path string.

public static class PathExtensions
{
    public static string GetLastPathSegment(this string path)
    {
        string lastPathSegment = path
            .Split(new string[] {@"\"}, StringSplitOptions.RemoveEmptyEntries)
            .LastOrDefault();

        return lastPathSegment;
    }
}

Example Usage:

lastSegment = Paths.GetLastPathSegment(@"C:\Windows\System32\drivers\etc");
lastSegment = Paths.GetLastPathSegment(@"C:\Windows\System32\drivers\etc\");

Output: etc

Answer 3

You can do:

string dirName = new DirectoryInfo(@"C:\Users\me\Projects\myProject\").Name;

Or use Path.GetFileName like (with a bit of hack):

string dirName2 = Path.GetFileName(
              @"C:\Users\me\Projects\myProject".TrimEnd(Path.DirectorySeparatorChar));

Path.GetFileName returns the file name from the path, if the path is terminating with \ then it would return an empty string, that is why I have used TrimEnd(Path.DirectorySeparatorChar)
