Examples

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

using System;
using System.IO;

class Program
{

    static void Main(string[] args)
    {
        try
        {

            //  Specify a directory name that does not exist for this demo.
            string dir = @"c:\78fe9lk";

            // If this directory does not exist, a DirectoryNotFoundException is thrown
            // when attempting to set the current directory.
            Directory.SetCurrentDirectory(dir);
        }
        catch (DirectoryNotFoundException dirEx)
        {
            // Let the user know that the directory did not exist.
            Console.WriteLine("Directory not found: " + dirEx.Message);
        }
    }
}

Imports System.IO

Module Module1
    Sub Main()
        Try

            ' 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.
            Directory.SetCurrentDirectory(dir)

        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

Remarks

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.

Constructors

DirectoryNotFoundException()	Initializes a new instance of the DirectoryNotFoundException class with its message string set to a system-supplied message and its HRESULT set to COR_E_DIRECTORYNOTFOUND.
DirectoryNotFoundException(SerializationInfo, StreamingContext)	Obsolete. Initializes a new instance of the DirectoryNotFoundException class with the specified serialization and context information.
DirectoryNotFoundException(String, Exception)	Initializes a new instance of the DirectoryNotFoundException class with a specified error message and a reference to the inner exception that is the cause of this exception.
DirectoryNotFoundException(String)	Initializes a new instance of the DirectoryNotFoundException class with its message string set to `message` and its HRESULT set to COR_E_DIRECTORYNOTFOUND.
