Examples

The following example demonstrates creating a subdirectory. In this example, the created directories are removed once created. Therefore, to test this sample, comment out the delete lines in the code.

using namespace System;
using namespace System::IO;
int main()
{
   
   // Create a reference to a directory.
   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" );
   
   // Process that directory as required.
   // ...
   // Delete the subdirectory.
   dis->Delete( true );
   
   // Delete the directory.
   di->Delete( true );
}

using System;
using System.IO;

public class CreateSubTest
{
    public static void Main()
    {
        // Create 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");

        // Process that directory as required.
        // ...

        // Delete the subdirectory.
        dis.Delete(true);

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

open System.IO

// Create a reference to a directory.
let di = DirectoryInfo "TempDir"

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

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

// Process that directory as required.
// ...

// Delete the subdirectory.
dis.Delete true

// Delete the directory.
di.Delete true

Imports System.IO

Public Class CreateSubTest

    Public Shared Sub Main()
        ' Make a reference to a directory.
        Dim di As New DirectoryInfo("TempDir")

        ' Create the directory only if it does not already exist.
        If di.Exists = False Then
            di.Create()
        End If

        ' Create a subdirectory in the directory just created.
        Dim dis As DirectoryInfo = di.CreateSubdirectory("SubDir")

        ' Process that directory as required.
        ' ...

        ' Delete the subdirectory.
        dis.Delete(True)

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

Remarks

Any and all directories specified in path are created, unless some part of path is invalid. The path parameter specifies a directory path, not a file path. If the subdirectory already exists, this method does nothing.
