System.UnauthorizedAccessException：訪問路徑C

我正在嘗試構建一個自動備份和還原系統。System.UnauthorizedAccessException：訪問路徑C

我的日誌文件：

2012-08-02 22:34:06 - Init: Folder main created for server Teamdeathmatch 
2012-08-02 22:34:06 - Backup: Couldn't copy files: System.UnauthorizedAccessException: Access to the path 'C:/temp/backups/Teamdeathmatch/server/main' is denied. 
    at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) 
    at System.IO.File.InternalCopy(String sourceFileName, String destFileName, Boolean overwrite) 
    at System.IO.File.Copy(String sourceFileName, String destFileName, Boolean overwrite) 
    at BackupRollback.Backup.getServerFiles() in C:\Users\jordi\Desktop\ConsoleApplication1 - kopie\Backup.cs:line 51

目標和文件存在。

我希望任何人都可以幫助我。還有一些關於我自c-sharp編程的反饋對我來說是新的。

謝謝

你正在運行這行代碼 string [] fileEntries = Directory.GetDirectories（「c：/ Gameservers」）;您的本地機器或遠程服務器機器上的 .. ?? – MethodMan 2012-08-02 21:07:54

爲了明顯地避免這種情況發生，您是否有權寫入該目錄？嘗試而不是寫入C：\ temp \ backups寫入其他地方，如我的文檔。那樣有用嗎？ – Sam 2012-08-02 21:08:38

c：/ Gameservers在我的遠程機器上。 – 2012-08-03 12:19:37

File.Copy（源，目的地）

你有你的參數逆轉。試試這個。

File.Copy"C:/Gameservers/" + servername + "/server/main/server.cfg", 
     "C:/temp/backups/" + servername + "/server/main"); 
Log.Data("File server.cfg copied for server " + servername);
