Directory.Delete Method (String)

Deletes an empty directory from a specified path.

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

public static void Delete(
	string path
)

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.

.

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 null.

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.

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.

Windows Mobile for Pocket PC, Windows Mobile for Smartphone, Windows CE Platform Note: Some device file systems do not support relative paths. Specify absolute path information.

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

using System;
using System.IO;

class Test 
{
    public static void Main() 
    {
        // Specify the directories you want to manipulate.
        string path = @"c:\MyDir";
        string subPath = @"c:\MyDir\temp";

        try 
        {
            // Determine whether the directory exists. 
            if (!Directory.Exists(path)) 
            {
                // Create the directory if it does not exist.
                Directory.CreateDirectory(path);
            }


            if (!Directory.Exists(subPath)) 
            {
                // Create the subdirectory if it does not exist.
                Directory.CreateDirectory(subPath);
            }

            // This 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 (Exception) 
        {
            Console.WriteLine("The Delete operation failed as expected.");
        } 
        finally {}
    }
}
