Directory.GetDirectoryRoot Method

---

Class

System.IO.Directory

Syntax

     Dim result As String = Directory.GetDirectoryRoot(path) 

path (required; String)

A valid path to a directory

Description

The GetDirectoryRoot method returns the name of the root directory of the drive on which path resides. For example, the code:

     Directory.GetDirectoryRoot("c:\Program Files\MyCompany") 

returns the string "C:\" as the root directory.

Usage at a Glance

• path can be either an absolute path or a relative path from the current directory.

• path can be either a path on the local system, the path of a mapped network drive, or a UNC path. For example, the code:

       Directory.GetDirectoryRoot("\\SomeServer\C\SomeFolder") 

  
  

  returns "\\SomeServer\C," and if the directory \\SomeServer\C\SomeFolder maps to the local "Z" drive, then:

   Directory.GetDirectoryRoot("Z:\temp") 

  
  

  returns Z:\.

• path cannot contain wildcard characters.

Version Differences

Visual Basic 2005 includes a My.Computer.FileSystem.GetDirectoryInfo method that provides access to detailed information about a directory.
