Add timer to a Windows Forms application
提问by knowledgehunter
I want to add a timer rather than a countdown which automatically starts when the form loads. Starting time should be 45 minutes and once it ends, i.e. on reaching 0 minutes, the form should terminate with a message displayed. How can I do this?
我想添加一个计时器，而不是在表单加载时自动启动的倒计时。开始时间应为 45 分钟，一旦结束，即在达到 0 分钟时，该表单应以显示消息结束。我怎样才能做到这一点？

Bit more detail:
更多细节：
private void Form1_Load(object sender, EventArgs e)
{
Timer MyTimer = new Timer();
MyTimer.Interval = (45 * 60 * 1000); // 45 mins
MyTimer.Tick += new EventHandler(MyTimer_Tick);
MyTimer.Start();
}
private void MyTimer_Tick(object sender, EventArgs e)
{
MessageBox.Show("The form will now be closed.", "Time Elapsed");
this.Close();
}

Something like this in your form main. Double click the form in the visual editor to create the form load event.
像这样的东西在你的表单中。在可视化编辑器中双击表单以创建表单加载事件。
Timer Clock=new Timer();
Clock.Interval=2700000; // not sure if this length of time will work
Clock.Start();
Clock.Tick+=new EventHandler(Timer_Tick);
Then add an event handler to do something when the timer fires.
然后添加一个事件处理程序以在计时器触发时执行某些操作。
public void Timer_Tick(object sender,EventArgs eArgs)
{
if(sender==Clock)
{
// do something here
}
}

Then add a button or something on the form and inside its event, just open this app ie:
然后在表单上和它的事件中添加一个按钮或其他东西，只需打开这个应用程序，即：
{
{
Process.Start(@"C:\Program Files (x86)\Free Desktop Timer\DesktopTimer");
Process.Start(@"C:\Program Files (x86)\Free Desktop Timer\DesktopTimer");
}
}
