Directory.GetFiles Method (String)

Returns the names of files (including their paths) in the specified directory.

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

Public Shared Function GetFiles ( _
	path As String _
) As String()
Dim path As String 
Dim returnValue As String()

returnValue = Directory.GetFiles(path)


Type: System.String

The directory from which to retrieve the files.

Return Value

Type: System.String()
A String array of file names in the specified directory. File names include the full path.


path is a file name.


A network error has occurred.


The caller does not have the required permission.


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


path is Nothing.


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.


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

The returned file names are appended to the supplied path parameter.

If there are no files, this method returns an empty array.

This method is identical to GetFiles with the asterisk (*) specified as the search pattern.

The path parameter is permitted to 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.

The order of the returned file names is not guaranteed; use the Sort method if a specific sort order is required.

The path parameter is not case-sensitive.

The following example demonstrates how to use the GetFiles method to return file names from a user-specified location. The example is configured to catch all errors common to this method.
