Public Enumeration SearchOption

Member nameDescription

Includes the current directory and all its subdirectories in a search operation. This option includes reparse points such as mounted drives and symbolic links in the search.


Includes only the current directory in a search operation.

If you choose AllDirectories in your search and the directory structure contains a link that creates a loop, the search operation enters an infinite loop.

The following example lists all the directories and files that begin with the letter "c", as in "c:\". In this example, the SearchOption is used to specify that only the top-level directory should be searched.

Class App
    Public Shared Sub Main()
        ' Specify the directory you want to manipulate.
        Dim path As String = "c:\\"
        Dim searchPattern As String = "c*"

        Dim di As DirectoryInfo = New DirectoryInfo(path)
        Dim directories() As DirectoryInfo = _
            di.GetDirectories(searchPattern, SearchOption.TopDirectoryOnly)

        Dim files() As FileInfo = _
            di.GetFiles(searchPattern, SearchOption.TopDirectoryOnly)

        Console.WriteLine( _
            "Directories that begin with the letter 'c' in {0}", path)
        Dim dir As DirectoryInfo
        For Each dir In directories
            Console.WriteLine( _
                "{0,-25} {1,25}", dir.FullName, dir.LastWriteTime)
        Next dir

        Console.WriteLine( _
            "Files that begin with the letter 'c' in {0}", path)
        Dim file As FileInfo
        For Each file In files
            Console.WriteLine( _
                "{0,-25} {1,25}", file.Name, file.LastWriteTime)
        Next file
    End Sub
