WinForm实现页面按钮定时隐藏功能

private void Form1_Load(object sender, EventArgs e)
{
  System.Timers.Timer t = new System.Timers.Timer(3000);
  t.Elapsed += new System.Timers.ElapsedEventHandler(OnTimedEvent);
  t.Enabled = true;
  t.AutoReset = false;
}

private delegate void SetVisibleCallback();
//在给label1.visible赋值的地方调用以下方法即可
private void SetVisible()
{
  // InvokeRequired需要比较调用线程ID和创建线程ID
  // 如果它们不相同则返回true
  if (this.label1.InvokeRequired)
  {
    SetVisibleCallback d = new SetVisibleCallback(SetPan);
    this.Invoke(d);
   }
   else
   {
    this.label1.Visible = false;
   }
}

private void OnTimedEvent(object sender, System.Timers.ElapsedEventArgs e)
{
  SetPan();
}

CheckForIllegalCrossThreadCalls = false;////避免跨线程的问题
label1.Visible = false;
