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 = ;

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