How to navigate a few folders up?

Other simple way is to do this:

string path = @"C:\Folder1\Folder2\Folder3\Folder4";
string newPath = Path.GetFullPath(Path.Combine(path, @"..\..\"));

Note This goes two levels up. The result would be: newPath = @"C:\Folder1\Folder2\";

if c:\folder1\folder2\folder3\bin is the path then the following code will return the path base folder of bin folder

//string directory=System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString());

string directory=System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString();

ie,c:\folder1\folder2\folder3

if you want folder2 path then you can get the directory by

string directory = System.IO.Directory.GetParent(System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString()).ToString();

then you will get path as c:\folder1\folder2\

You can use ..\path to go one level up, ..\..\path to go two levels up from path.

You can use Path class too.
