DirectoryInfo.Delete Method (Boolean)

Deletes this instance of a DirectoryInfo, specifying whether to delete subdirectories and files.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)
public void Delete(
	bool recursive
)

Parameters

recursive
Type: System.Boolean

true to delete this directory, its subdirectories, and all files; otherwise, false.

ExceptionCondition
UnauthorizedAccessException

The directory contains a read-only file.

IOException

The directory is read-only.

-or-

The directory contains one or more files or subdirectories and recursive is false.

-or-

The directory is the application's current working directory.

SecurityException

The caller does not have the required permission.

If the DirectoryInfo has no files or subdirectories, this method deletes the DirectoryInfo even if recursive is false. Attempting to delete a DirectoryInfo that is not empty when recursive is false throws an IOException.

For a list of common I/O tasks, see Common I/O Tasks.

The following example demonstrates deleting a directory. Because the directory is removed, first comment out the Delete line to test that the directory exists. Then uncomment the same line of code to test that the directory was removed successfully.

using System;
using System.IO;

public class DeleteTest 
{
    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 == false)
            di.Create();

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

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

        // Delete the subdirectory. The true indicates that if subdirectories 
        // or files are in this directory, they are to be deleted as well.
        dis.Delete(true);

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