C＃定时器关机，睡眠并重启PC [英] C# timer to shutdown, sleep and restart PC

问题描述

我想按小时，分钟和秒钟的按钮运行= 0

  int  hours =  1 ; 
  int  minutes =  60 ; 
  int  seconds =  60 ; 
  private   void  timer1_Tick（ object  sender，EventArgs e）
 {
 
 
  if （seconds ==  0 && minutes ==  0 && hours ==  0 ）
 {
 
 timer1.Stop（）; 
定时器t =（定时器）发送器; 
按钮b = 新按钮（）; 
 开关（按下）
 {
  case    btnShutdown：Process.Start（  shutdown，  / s / t 0） ;  break ; 
  case    btnSleep ：Application.SetSuspendState（PowerState.Suspend， false ， false ）;  break ; 
  case    btnRestart ：Process.Start（  shutdown，  / r / t 0）;  break ; 
} 
} 
 
 其他 如果（秒==  0 ）
 {
分钟 - ; 
秒=  59 ; 
} 
 其他 如果（分钟==  0 ）
 {
 hours--; 
分钟=  59 ; 
} 
 
 
秒 - ; 
 lblSecondes.Text = seconds.ToString（）; 
 lbltimeShow.Text =（小时+  ： + minutes）.ToString（）; 
} 
 

我尝试过：



i尝试

 如果 （秒==  0 && minutes ==  0 && hours ==  0 ）
 {
 
 timer1.Stop（）; 
定时器t =（定时器）发送器; 
按钮b = 新按钮（）; 
 开关（按下）
 {
  case    btnShutdown：Process.Start（  shutdown，  / s / t 0） ;  break ; 
  case    btnSleep ：Application.SetSuspendState（PowerState.Suspend， false ， false ）;  break ; 
  case    btnRestart ：Process.Start（  shutdown，  / r / t 0）;  break ; 
} 
} 
 

但不工作

解决方案

请查看Richard Deeming和我的问题的评论。这个问题没有解释，所以我只能告诉你如何对你的代码进行不可接受的一般设计。它的主要问题是：

魔术字符串 - 维基百科，免费的百科全书 [ ^ ]，

另见Anti-pattern - 维基百科，免费的百科全书 [ ^ ]。



要获得一些基本想法，请查看这：

 内部 枚举 SystemSessionAction {关机，睡眠，重启，休眠，锁定，} 
 
  int  delay =  0 ; 
 
  //   ...  
 
 Button buttonShutdown =  //   ...  
按钮buttonSleep =  //   ...  
  //   ...  
 delay =  //   ...  
  //   ...  
 
 buttonShutdown.Click + =（sender，eventArgs）= >  {
 EndSystemSession（SystemSessionAction.Shutdown，delay）; 
}; 
 buttonSleep.Click + =（sender，eventArgs）= >  {
 EndSystemAction（SystemSessionAction.Sleep，delay）; 
}; 
 
  //   ...  
 
 < span class =code-keyword> void  EndSystemAction（SystemSessionAction操作， int 延迟）{ / *   ... * / } 
  //  你不必处理延迟，我添加它只是为了说明 
  //  你可以添加很多动作选项

嗯，你的意思是时间相等到MidNight（00:00:00）然后app必须执行一个特定的代码？

如果这就是你的意思那么我会在这里检查它。

1.我开始计时器

2.我检查它是否是午夜

3.如果是，那么只需停止计时器并执行你的代码



要检查的代码：

  bool  isMidnight = DateTime.Today.Ticks ==  0 ; 

i want code in buttons run when hours, minutes and seconds=0

int hours = 1;
int minutes = 60;
int seconds = 60;
private void timer1_Tick(object sender, EventArgs e)
{


    if (seconds == 0 && minutes == 0 && hours == 0)
    {

        timer1.Stop();
         Timer t = (Timer)sender;
         Button b = new Button();
         switch (pressed)
         {
             case "btnShutdown": Process.Start("shutdown", "/s /t 0"); break;
             case "btnSleep": Application.SetSuspendState(PowerState.Suspend, false, false); break;
             case "btnRestart": Process.Start("shutdown", "/r /t 0"); break;
         }
    }

    else if (seconds == 0)
    {
        minutes--;
        seconds = 59;
    }
    else if (minutes == 0)
    {
        hours--;
        minutes = 59;
    }


    seconds--;
    lblSecondes.Text = seconds.ToString();
    lbltimeShow.Text = (hours + " : " + minutes).ToString();
}

What I have tried:

i tried

if (seconds == 0 && minutes == 0 && hours == 0)
           {

               timer1.Stop();
                Timer t = (Timer)sender;
                Button b = new Button();
                switch (pressed)
                {
                    case "btnShutdown": Process.Start("shutdown", "/s /t 0"); break;
                    case "btnSleep": Application.SetSuspendState(PowerState.Suspend, false, false); break;
                    case "btnRestart": Process.Start("shutdown", "/r /t 0"); break;
                }
           }

but not work

解决方案

Please see comments to the question by Richard Deeming, and mine. The problem is not explained, so I can only can give you the idea how the unacceptably bad general design of your code. It's major problem is this:
Magic string — Wikipedia, the free encyclopedia[^],
see also Anti-pattern — Wikipedia, the free encyclopedia[^].

To get some basic ideas, please look at this:

internal enum SystemSessionAction { Shutdown, Sleep, Restart, Hibernate, Lock, }

int delay = 0;

// ...

Button buttonShutdown = //...
Button buttonSleep = //...
// ...
delay = // ...
// ...

buttonShutdown.Click += (sender, eventArgs) => {
    EndSystemSession(SystemSessionAction.Shutdown, delay);
};
buttonSleep.Click += (sender, eventArgs) => {
    EndSystemAction(SystemSessionAction.Sleep, delay);
};

// ...

void EndSystemAction(SystemSessionAction action, int delay) { /* ... */ }
// you don't have to deal with delay, I added it just to illustrate that
// you can add many action options

Hmmm , you mean when the time is equal to MidNight (00:00:00) then app must execute a specific code ?
if that's what you meant then here how I would check it.
1. I start the timer
2. I check if it's midnight or not
3. if it's, then simply stop the timer and execute your code

Code to check :

bool isMidnight = DateTime.Today.Ticks == 0;
