如何检测用户是否删除了文件？ [英] How to detect if user has deleted a file or not?

问题描述

大家好，我已经在c＃.net上制作了试用版windows应用程序。试用信息文件存储在系统文件夹中。现在我想让该文件无法删除，因为如果它被删除，那么用户将永远使用我的应用程序。有没有办法做到这一点？或者如何在应用程序第二次启动时检测用户是否删除了该文件？

Hi, I have made a trial version windows application in c#.net. The trial info file is stored in the system folder. Now i want to make that file undeletable because if it is deleted then the user will use my application forever. So is there any way to do this? or how can i detect if the user has deleted that file when application start second time?

推荐答案

static class Program
  {
      /// <summary>
      /// The main entry point for the application.
      /// </summary>
      [STAThread]
      static void Main()
      {
         if (File.Exist(Path))
         {
           .... Checking File  Data....
          Application.EnableVisualStyles();
          Application.SetCompatibleTextRenderingDefault(false);
          Application.Run(new Form1());
         }
      }
  }
