   DirectoryInfo^ di = gcnew DirectoryInfo( "TempDir" );
   
   // Create the directory only if it does not already exist.
   if (  !di->Exists )
      di->Create();

   
   // Create a subdirectory in the directory just created.
   DirectoryInfo^ dis = di->CreateSubdirectory( "SubDir" );
   
   // Get a reference to the parent directory of the subdirectory you just made.
   DirectoryInfo^ parentDir = dis->Parent;
   Console::WriteLine( "The parent directory of '{0}' is '{1}'", dis->Name, parentDir->Name );
   
   // Delete the parent directory.
   di->Delete( true );
}

using System;
using System.IO;

public class MoveToTest
{
    public static void Main()
    {

        // Make a reference to a directory.
        DirectoryInfo di = new DirectoryInfo("TempDir");

        // Create the directory only if it does not already exist.
        if (!di.Exists)
            di.Create();

        // Create a subdirectory in the directory just created.
        DirectoryInfo dis = di.CreateSubdirectory("SubDir");

        // Get a reference to the parent directory of the subdirectory you just made.
        DirectoryInfo parentDir = dis.Parent;
        Console.WriteLine("The parent directory of '{0}' is '{1}'", dis.Name, parentDir.Name);

        // Delete the parent directory.
        di.Delete(true);
    }
}

if not di.Exists then
    di.Create()

// Create a subdirectory in the directory just created.
let dis = di.CreateSubdirectory "SubDir"

// Get a reference to the parent directory of the subdirectory you just made.
let parentDir = dis.Parent
printfn $"The parent directory of '{dis.Name}' is '{parentDir.Name}'"

        ' Get a reference to the parent directory of the subdirectory you just made.
        Dim parentDir As DirectoryInfo = dis.Parent
        Console.WriteLine("The parent directory of '{0}' is '{1}'", dis.Name, parentDir.Name)

        ' Delete the parent directory.
        di.Delete(True)
    End Sub

Remarks

Viktigt

In .NET Framework, Parent returns a relative path. In .NET Core, Parent returns a fully qualified path.

To ensure consistent behavior across versions and to make your intent explicit, retrieve the value of one of the following properties on the DirectoryInfo instance returned by Parent.

Name, which returns the simple name of the directory (such as bin).
FullName, which returns the absolute path of the directory.
