範例

下列範例顯示如何從強制執行DirectoryNotFoundException和復原。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

備註

DirectoryNotFoundException使用具有值0x80070003 的 HRESULT COR_E_DIRECTORYNOTFOUND。DirectoryNotFoundException uses the HRESULT COR_E_DIRECTORYNOTFOUND which has the value 0x80070003. 請注意DirectoryNotFoundException , 當 COM Interop 程式看到 HRESULT STG_E_PATHNOTFOUND, 其值為0x80030003 時, 也會擲回。Note that DirectoryNotFoundException is also thrown when COM interop programs see the HRESULT STG_E_PATHNOTFOUND, which has the value 0x80030003.

如果您的程式碼PathDiscovery沒有許可權, 此例外狀況的錯誤訊息可能只會包含檔案或目錄名稱, 而不是完整路徑。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.
