public FileAttributes Attributes { get; set; }
/** @property */

Property Value

The specified path is invalid, such as being on an unmapped drive.

SecurityException

The caller does not have the required permission.

Refresh cannot initialize the data.

When first called, FileSystemInfo calls Refresh and returns the cached information on APIs to get attributes and so on. On subsequent calls, you must call Refresh to get the latest copy of the information.

The value of this property is a combination of the archive, compressed, directory, hidden, offline, read-only, system, and temporary file attribute flags.

The following example demonstrates the Attributes property. This code example is part of a larger example provided for the FileSystemInfo class.

Sub DisplayFileSystemInfoAttributes(ByVal fsi As IO.FileSystemInfo)
    ' Assume that this entry is a file.
    Dim entryType As String = "File"

    ' Determine if this entry is really a directory.
    If (fsi.Attributes And FileAttributes.Directory) <> 0 Then
        entryType = "Directory"
    End If

    ' Show this entry's type, name, and creation date.
    Console.WriteLine("{0} entry {1} was created on {2:D}", _
        entryType, fsi.FullName, fsi.CreationTime)
End Sub
