SearchOption Enumeration

Specifies whether to search the current directory, or the current directory and all subdirectories.

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

'Declaration
<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public Enumeration SearchOption
'Usage
Dim instance As SearchOption

Member nameDescription
TopDirectoryOnlyIncludes only the current directory in a search.
AllDirectoriesIncludes the current directory and all the subdirectories in a search operation. This option includes reparse points like mounted drives and symbolic links in the search.

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 code example lists all of the directories and files that begin with the letter "c" in "c:\". In this example, the SearchOption is used to specify not to search all subdirectories.

    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

        Next dir

        Console.WriteLine()
        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 
End Class
