DirectoryInfo.GetDirectories Method (String, SearchOption)

Note: This method is new in the .NET Framework version 2.0.

Returns an array of directories in the current DirectoryInfo matching the given search criteria and using a value to determine whether to search subdirectories.

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

public DirectoryInfo[] GetDirectories (
	string searchPattern,
	SearchOption searchOption
)
public DirectoryInfo[] GetDirectories (
	String searchPattern, 
	SearchOption searchOption
)
public function GetDirectories (
	searchPattern : String, 
	searchOption : SearchOption
) : DirectoryInfo[]

Parameters

searchPattern

The search string, such as "System*", used to search for all directories beginning with the word "System".

searchOption

One of the values of the SearchOption enumeration that specifies whether the search operation should include only the current directory or should include all subdirectories.

Return Value

An array of type DirectoryInfo matching searchPattern.

Exception typeCondition

ArgumentNullException

searchPattern is a null reference (Nothing in Visual Basic).

DirectoryNotFoundException

The path encapsulated in the DirectoryInfo object is invalid, such as being on an unmapped drive.

SecurityException

The caller does not have the required permission.

Wildcards are permitted. For example, the searchPattern string "*t" searches for all directory names in path ending with the letter "t". The searchPattern string "s*" searches for all directory names in path beginning with the letter "s".

The string ".." can only be used in searchPattern if it is specified as a part of a valid directory name, such as in the directory name "a..b". It cannot be used to move up the directory hierarchy.

If there are no subdirectories, or no subdirectories are found that match searchPattern, this method returns only the root directory.
