將文件保存到'C：\ Windows \ System32 \ dns'導致'找不到路徑的一部分'錯誤

我已經寫了一個windows窗體（.net 4）應用程序，需要將文件寫入文件夾'C：\ Windows \ System32 \ dns'。當這行代碼運行時：將文件保存到'C： Windows System32 dns'導致'找不到路徑的一部分'錯誤

File.WriteAllText(dnsFileLocation, luxDns)

我得到以下錯誤，有誰知道爲什麼？

注意：即使我以管理員身份運行應用程序，也會發生這種情況！

** * ** JIT調試 ** * **** 只啓用即時（JIT）調試，該應用程序或計算機（Machine.config中）的config文件必須有 jitDebugging值在system.windows.forms部分中設置。該應用程序還必須在啓用調試的情況下進行編譯。

例如：

<configuration> 
    <system.windows.forms jitDebugging="true" /> 
</configuration>

啓用JIT調試後，任何未處理的異常將被髮送到計算機上註冊，而不是由此對話框處理的JIT調試器。

您是否正在運行64位Windows？如果是，那麼這可能是您的問題，因爲您將在另一個目錄中重定向。

您需要實現
http://msdn.microsoft.com/en-us/library/windows/desktop/aa365743%28v=vs.85%29.aspx和 http://msdn.microsoft.com/en-us/library/windows/desktop/aa365745%28v=vs.85%29.aspx 以暫時禁用才能訪問該文件夾的64位重定向。

是我運行Windows 64，我會檢查這些鏈接了，謝謝！ – Darthtong 2012-04-17 11:44:55

你可以檢查目錄是否存在？由於system32是一個windows文件夾，要在其中創建文件和文件夾需要特殊的權限。運行win窗體應用程序的用戶是否有權在system32文件夾內創建文件夾/文件？

他說，他跑作爲問題管理 – Jacxel 2012-04-17 11:24:42

是目錄肯定是存在的，它的DNS服務器保留它的區域文件等我運行的應用程序作爲管理員用戶，以便應該有權限的目錄！ – Darthtong 2012-04-17 11:28:09
