Configuration.Save在網絡驅動器上

Question

我爲一些簡單任務開發了Winforms應用程序。此應用程序具有保存一些設置的App.config文件。我在應用程序中創建了一個標籤頁，我可以使用Configuration類來調整配置文件的設置。我使用應用程序本身中的「保存」按鈕保存到App.config中，該應用程序使用Configuration.Save。

但我在保存到網絡文件夾的配置文件時遇到了麻煩。當我將設置保存到本地文件夾中的文件（如：C：\）時，一切正常。我的意思是我將.exe和.config複製到網絡文件夾（例如：\\ folder \ application.exe），當我嘗試使用Configuration.Save將設置保存到配置文件時，出現以下錯誤：

System.UnauthorizedAccessException: Attempted to perform an unauthorized operation.

編輯：或者我可以只使用StreamWriter而不是配置？

編輯2：

這是堆棧跟蹤：

該文件可能已在該位置作爲管理員這將使其無法使用任何其他非管理用戶創建。

你需要設置文件權限讓大家喜歡這個

private void CreateSettingsFile(string path) 
    { 
     XDocument document = new XDocument(); 
     XElement rootElement = new XElement("settings"); 
     document.Add(rootElement); 
     document.Save(path); 
     var accessControl = File.GetAccessControl(path); 
     var everyone = new SecurityIdentifier(WellKnownSidType.WorldSid, null); 
     accessControl.AddAccessRule(new FileSystemAccessRule(everyone, 
                  FileSystemRights.FullControl | 
                  FileSystemRights.Synchronize, 
                  AccessControlType.Allow)); 

     manager = new XmlSettingsManager(document,() => XDocument.Load("file://" + Path.Combine(AppDomain.CurrentDomain.BaseDirectory, this.settingsPath)), 
      x => x.Save(this.settingsPath)); 
     File.SetAccessControl(path, accessControl); 
    }
