如何让程序能够开机自动运行的C#代码

//此方法把启动项加载到注册表中  //获得应用程序路径  string strAssName = Application.StartupPath + @"/" + Application.ProductName + @".exe";  //获得应用程序名  string ShortFileName = Application.ProductName;  RegistryKey rgkRun = Registry.LocalMachine.OpenSubKey("SOFTWARE//Microsoft//Windows//CurrentVersion//Run", true);  if (rgkRun == null)  {      rgkRun = Registry.LocalMachine.CreateSubKey("SOFTWARE//Microsoft//Windows//CurrentVersion//Run");  }  rgkRun.SetValue(ShortFileName, strAssName);    //此删除注册表中启动项  //获得应用程序名  string ShortFileName = Application.ProductName;  RegistryKey rgkRun = Registry.LocalMachine.OpenSubKey("SOFTWARE//Microsoft//Windows//CurrentVersion//Run", true);  if (rgkRun == null)  {      rgkRun = Registry.LocalMachine.CreateSubKey("SOFTWARE//Microsoft//Windows//CurrentVersion//Run");  }  rgkRun.DeleteValue(ShortFileName, false);
