VB .NET Language in a Nutshell

Name

Directory.GetFiles Method

Class

System.IO.Directory

Syntax

Directory.GetFiles(path [, searchpattern])

path

Use: Required

Data Type: String

A valid path to a directory

searchpattern

Use: Optional

Data Type: String

A file specification, including the wildcard characters * and ?

Return Value

An array of strings, each element of which contains the name of a file

Description

Returns the names of the files in a specified directory

Rules at a Glance

path can be either an absolute path (a complete path from the root directory to the directory whose filenames are to be retrieved) or a relative path (starting from the current directory to the directory whose filenames are to be retrieved).
path can be either a path on the local system, the path of a mapped network drive, or a UNC path.
path cannot contain wildcard characters.
If searchpattern is specified, the method returns only those files whose names match the string, which can contain wildcard characters. Otherwise, the function returns the names of all the files in the path directory.
If the directory specified by path has no files, or if no files match searchpattern, an empty array is returned.

Example

The following code displays all files in c:\ that have the extension .txt:

Dim sFiles(  ) As String
Dim i As Integer
sFiles = Directory.GetFiles("c:\", "*.txt")
For i = 0 To UBound(sFiles)
    Console.WriteLine(sFiles(i))
