How to get the parent directory in C#?

We can use the DirectoryInfo class to get a parent of a specified folder or directory in C#. You must import the System.IO before you can use this class.

using System.IO;

The Parent property of DirectoryInfo returns the parent directory as a DirectoryInfo. We can use the FullName property to get the full name of the directory. 

The following code snippet does the same.

string root = @"C:\Temp\Mahesh";
DirectoryInfo di = new DirectoryInfo(root);
Console.WriteLine(di.Parent.FullName);
