在每次定时刷新后，希望调用后台的AA(),怎样实现？

Answer 1

直接为timer绑定触发的方法即可。protected void Timer1_Tick(object sender, EventArgs e) &nbsp; &nbsp;{ &nbsp; &nbsp; &nbsp; &nbsp;//方法体 &nbsp; &nbsp;}调用AA()的话。在这个触发的方法里面调用吧。

Answer 2

protected void Timer1_Tick(object sender, EventArgs e) &nbsp; &nbsp;{ &nbsp; &nbsp; &nbsp; &nbsp;AA(); &nbsp; &nbsp;}public void AA(){}
