DirectoryNotFoundException Class

The exception that is thrown when part of a file or directory cannot be found.

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

<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public Class DirectoryNotFoundException _
	Inherits IOException
Dim instance As DirectoryNotFoundException

DirectoryNotFoundException uses the HRESULT COR_E_DIRECTORYNOTFOUND which has the value 0x80070003. Note that DirectoryNotFoundException is also thrown when COM interop programs see the HRESULT STG_E_PATHNOTFOUND, which has the value 0x80030003.

If your code does not have PathDiscovery permission, the error message for this exception may only contain file or directory names instead of fully qualified paths.

The following example shows how to force and recover from a DirectoryNotFoundException.

Imports System.IO

Module Module1
    Sub Main()

            ' Specify a directory name that does not exist for this demo. 
            Dim dir As String = "c:\78fe9lk" 

            ' If this directory does not exist, a DirectoryNotFoundException is thrown 
            ' when attempting to set the current directory.

        Catch ex As System.IO.DirectoryNotFoundException

            ' Let the user know that the directory did not exist.
            Console.WriteLine("Directory not found: " + ex.Message)
        End Try 
    End Sub 
End Module
