Configuration.Save在网络驱动器上

Question

我为一些简单任务开发了Winforms应用程序。此应用程序具有保存一些设置的App.config文件。我在应用程序中创建了一个标签页，我可以使用Configuration类来调整配置文件的设置。我使用应用程序本身中的“保存”按钮保存到App.config中，该应用程序使用Configuration.Save。

但我在保存到网络文件夹的配置文件时遇到了麻烦。当我将设置保存到本地文件夹中的文件（如：C：\）时，一切正常。我的意思是我将.exe和.config复制到网络文件夹（例如：\\ folder \ application.exe），当我尝试使用Configuration.Save将设置保存到配置文件时，出现以下错误：

System.UnauthorizedAccessException: Attempted to perform an unauthorized operation.

编辑：或者我可以只使用StreamWriter而不是配置？

这是堆栈跟踪：

该文件可能已在该位置作为管理员这将使其无法使用任何其他非管理用户创建。

你需要设置文件权限让大家喜欢这个

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); 
    }
