表单关闭后计时器不会触发 [英] Timer doesn't fire after Form closed

问题描述

我有一个使用 VS 设计器声明的带有 System.Windows.Forms.Timer 的 .NET 表单.计时器工作正常.关闭表单后，即使我重新创建 Timer 对象，计时器也不会触发事件.我已经将表单配置为永远不会关闭:

I have a .NET form with a System.Windows.Forms.Timer declared using the VS designer. The timer works fine. After I close the form, the timer doesn't fire events even if I recreate the Timer object. I've configured the Form to never close using this:

    void MainFormFormClosing(object sender, FormClosingEventArgs e)
    {
        // never close
        e.Cancel = true;

        // only hide
        this.Visible = false;

    }

如何让计时器触发事件​​?我做错了什么?

How do I make the timer fire events? What am I doing wrong?

推荐答案

我刚试过这个.在表单上添加一个WinForms Timer组件、加载时启动计时器和中调试当前时间调试窗口.对我来说很好用...

I just tried this one. Added a WinForms Timer component on the form, start timer on load, and debug current time in debug window. Workes fine for me...

public frmTimer()
{
    InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
    timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
    Debug.WriteLine(DateTime.Now.ToLongTimeString());
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    e.Cancel = true;
    this.Visible = false;
}
