     CreateDirectories();
 }

在我的工作工作站上没有这个问题。我现在尝试使用的帐户是管理员。

Answer 1

如果您的应用程序未以管理员身份运行，您可以重新启动您的应用程序并请求管理员权限。

 public void AskForAdminPrivileges()
 {
   try
     {

     var appName= System.AppDomain.CurrentDomain.FriendlyName;
     //Define process which should start:
     ProcessStartInfo processInfo = new ProcessStartInfo();
     processInfo.FileName = appName;
     processInfo.UseShellExecute = true;
     processInfo.Verb = "runas";         

     Process.Start(processInfo );

     }
     catch (Exception exp)
     {
         MessageBox.Show(exp.Message);
     }
 }
