WinForm中Application.Idle事件用法

Application.Idle 事件

描述：当应用程序完成处理并即将进入空闲状态时发生。如果您有必须执行的任务在线程变为空闲之前，请将它们附加到此事件。

    public partial class Form1 : Form
    {
        /// <summary>
        /// 空闲期间执行的次数
        /// </summary>
        private int executeTimes = 0;

        public Form1()
        {
            InitializeComponent();
        }

        private void btnGetTime_Click(object sender, EventArgs e)
        {
            Application.Idle += Application_Idle;
        }

        /// <summary>
        /// 当程序完成处理并进入空闲状态时发生
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void Application_Idle(object sender, EventArgs e)
        {
            txtTime.Text = DateTime.Now.ToString();

            executeTimes++;
            if (executeTimes==9)
            {
                Application.Idle -= Application_Idle;
                MessageBox.Show("已经在CPU空闲时间执行10次");
            }
        }
    }
