Remarks
NoteNote

To view the .NET Framework source code for this type, see the Reference Source. You can browse through the source code online, download the reference for offline viewing, and step through the sources (including patches and updates) during debugging; see instructions.

Use the DirectoryInfo class for typical operations such as copying, moving, renaming, creating, and deleting directories.

If you are going to reuse an object several times, consider using the instance method of DirectoryInfo instead of the corresponding static methods of the Directory class, because a security check will not always be necessary.

NoteNote

In members that accept a path as an input string, that path must be well-formed or an exception is raised. For example, if a path is fully qualified but begins with a space, the path is not trimmed in methods of the class. Therefore, the path is malformed and an exception is raised. Similarly, a path or a combination of paths cannot be fully qualified twice. For example, "c:\temp c:\windows" also raises an exception in most cases. Ensure that your paths are well-formed when using methods that accept a path string.

In members that accept a path, the path can refer to a file or just a directory. The specified path can also refer to a relative path or a Universal Naming Convention (UNC) path for a server and share name. For example, all the following are acceptable paths:

  • "c:\\MyDir\\MyFile.txt" in C#, or "c:\MyDir\MyFile.txt" in Visual Basic.

  • "c:\\MyDir" in C#, or "c:\MyDir" in Visual Basic.

  • "MyDir\\MySubdir" in C#, or "MyDir\MySubDir" in Visual Basic.

  • "\\\\MyServer\\MyShare" in C#, or "\\MyServer\MyShare" in Visual Basic.

By default, full read/write access to new directories is granted to all users.

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

The following example demonstrates how to copy a directory and its contents.

Imports System
Imports System.IO

Class CopyDir
    Shared Sub CopyAll(ByVal source As DirectoryInfo, ByVal target As DirectoryInfo)
        If (source.FullName.ToLower() = target.FullName.ToLower()) Then

        End If 

        ' Check if the target directory exists, if not, create it. 
        If Directory.Exists(target.FullName) = False Then
            Directory.CreateDirectory(target.FullName)
        End If 

        ' Copy each file into it's new directory. 
        For Each fi As FileInfo In source.GetFiles()
            Console.WriteLine("Copying {0}\{1}", target.FullName, fi.Name)
            fi.CopyTo(Path.Combine(target.ToString(), fi.Name), True)
        Next 

        ' Copy each subdirectory using recursion. 
        For Each diSourceSubDir As DirectoryInfo In source.GetDirectories()
            Dim nextTargetSubDir As DirectoryInfo = target.CreateSubdirectory(diSourceSubDir.Name)
            CopyAll(diSourceSubDir, nextTargetSubDir)

    ' Output will vary based on the contents of the source directory. 
End Class
using System;
using System.IO;

class CopyDir

    public static void CopyAll(DirectoryInfo source, DirectoryInfo target)
    {
        if (source.FullName.ToLower() == target.FullName.ToLower())
        {
            return;
        }

        // Check if the target directory exists, if not, create it.

            fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true);
        }

        // Copy each subdirectory using recursion. 
        foreach (DirectoryInfo diSourceSubDir in source.GetDirectories())
        {
            DirectoryInfo nextTargetSubDir =
                target.CreateSubdirectory(diSourceSubDir.Name);
            CopyAll(diSourceSubDir, nextTargetSubDir);
        }
    }
