IsolatedStorageFile.GetDirectoryNames Method (String)

July 28, 2014

Enumerates directories in an isolated storage scope that match a given pattern.

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

public string[] GetDirectoryNames(
	string searchPattern
)

Parameters

searchPattern
Type: System.String
A search pattern. Both single-character ("?") and multi-character ("*") wildcards are supported.

Return Value

Type: System.String []
An Array of the relative paths of directories in the isolated storage scope that match searchPattern. A zero-length array specifies that there are no directories that match.

ExceptionCondition
IsolatedStorageException

The store has been removed.

-or-

Isolated storage is disabled.

ArgumentException

searchPattern is badly formed.

ArgumentNullException

searchPattern is null.

DirectoryNotFoundException

Cannot find a part of the searchPattern.

ObjectDisposedException

The store has been disposed.

Wildcard characters must only be in the final element of a searchPattern. For instance, "directory1/*etc*" is a valid search string, but "*etc*/directory" is not.

The searchPattern "Project\Data*" will give all subdirectories of Project beginning with Data in the isolated storage scope. The searchPattern "*" will return all directories located in the root. For complete description of search string criteria, see the Directory class.

The following example gets an array of subdirectory names.


// Find subdirectories within the MyApp1
// directory using the multi character '*' wildcard.
string[] subDirectories =
    store.GetDirectoryNames(Path.Combine("MyApp1", "*"));
