Directory.Delete Method (String)

Deletes an empty directory from a specified path.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public Shared Sub Delete ( _
	path As String _
)

Parameters

path
Type: System.String
The name of the empty directory to remove. This directory must be writable or empty.

ExceptionCondition
IOException

A file with the same name and location specified by path exists.

-or-

The directory is the application's current working directory.

-or-

The directory specified by path is not empty.

-or-

The directory is read-only or contains a read-only file.

-or-

The directory is being used by another process.

-or-

There is an open handle on the directory, and the operating system is Windows XP or earlier. This open handle can result from directories. For more information, see How to: Enumerate Directories and Files.

UnauthorizedAccessException

The caller does not have the required permission.

ArgumentException

path is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars.

ArgumentNullException

path is Nothing.

PathTooLongException

The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters and file names must be less than 260 characters.

DirectoryNotFoundException

path does not exist or could not be found.

-or-

path refers to a file instead of a directory.

-or-

The specified path is invalid (for example, it is on an unmapped drive).

This method behaves identically to Delete(String, Boolean) with false specified for the second parameter.

The path parameter may specify relative or absolute path information. Relative path information is interpreted as relative to the current working directory. To obtain the current working directory, see GetCurrentDirectory.

Trailing spaces are removed from the end of the path parameter before deleting the directory.

This method throws an IOException if the directory specified in the path parameter contains files or subdirectories.

The path parameter is not case-sensitive.

In some cases, if you have the specified directory open in Windows Explorer, the Delete method may not be able to delete it.

The following code example deletes the specified directory or throws an exception if there are subdirectories.

Imports System.IO

Public Class Test

    Public Shared Sub Main()
        ' Specify the directories you want to manipulate.
        Dim path As String = "c:\MyDir"
        Dim subPath As String = "c:\MyDir\temp"

        Try
            ' Determine whether the directory exists.
            If Directory.Exists(path) = False Then
                ' Create the directory if it does not exist.
                Directory.CreateDirectory(path)
            End If

            ' Determine whether the subdirectory exists.
            If Directory.Exists(subPath) = False Then
                ' Create the subdirectory if it does not exist.
                Directory.CreateDirectory(SubPath)
            End If

            ' This Delete operation will not be allowed because there are subdirectories.
            Console.WriteLine("I am about to attempt to delete {0}.", path)
            Directory.Delete(path)
            Console.WriteLine("The Delete operation was successful, which was unexpected.")

        Catch
            Console.WriteLine("The Delete operation failed as expected.")
        End Try
    End Sub
End Class
