IsolatedStorageFile.GetDirectoryNames Method

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
)
public String[] GetDirectoryNames (
	String searchPattern
)
public function GetDirectoryNames (
	searchPattern : String
) : String[]

Parameters

searchPattern

A search pattern. Both single-character ("?") and multi-character ("*") wildcards are supported.

Return Value

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.

Exception typeCondition

ArgumentNullException

The searchPattern was a null reference (Nothing in Visual Basic).

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.

For information on getting file names, see the GetFileNames method.

The Finding Existing Files and Directories example demonstrates the use of the GetDirectoryNames method.

The following code example demonstrates the GetDirectoryNames method. For the complete context of this example, see the IsolatedStorageFile overview.

    String[] dirNames = isoFile.GetDirectoryNames("*");
    String[] fileNames = isoFile.GetFileNames("Archive\\*");

    // Delete all the files currently in the Archive directory.

    if (fileNames.Length > 0)
    {
        for (int i = 0; i < fileNames.Length; ++i)
        {
            // Delete the files.
            isoFile.DeleteFile("Archive\\" + fileNames[i]);
        }
        // Confirm that no files remain.
        fileNames = isoFile.GetFileNames("Archive\\*");
    }


    if (dirNames.Length > 0)
    {
        for (int i = 0; i < dirNames.Length; ++i)
        {
            // Delete the Archive directory.
        }
    }
    dirNames = isoFile.GetDirectoryNames("*");
    isoFile.Remove();
}
catch (Exception e)
{
    Console.WriteLine(e.ToString());
}
