Gets the names of subdirectories in the specified directory.
[Visual Basic]
Overloads Public Shared Function GetDirectories( _
ByVal path As String _
) As String()
[C#]
public static string[] GetDirectories(
string path
);
[C++]
public: static String* GetDirectories(
String* path
) __gc[];
[JScript]
public static function GetDirectories(
path : String
) : String[];
Parameters
- path
- The path for which an array of subdirectory names is returned.
Return Value
An array of type String containing the names of subdirectories in path.
Exceptions
Remarks
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.
This method is identical to GetDirectories(String, String) with the asterisk (*) specified as the search pattern.
The names returned by this method are prefixed with the directory information provided in path.
The path parameter is not case-sensitive.
For an example of using this method, see the Example section below. The following table lists examples of other typical or related I/O tasks.
Example
The following example takes an array of file or directory names on the command line, determines what kind of name it is, and processes it appropriately.
