this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(this.timer1_Elapsed);

运行后错误提示为上句中的：“System.Windows.Forms.Timer”并不包含“Elapsed”的定义。

这就很郁闷了，如果系统自己没定义timer的这个Elapsed事件的话偶该怎么办？？

偶用的是vs.net2005..生成的主要3段：

--------------------
至于新添加的MainWindow.cs就不用写出来了....


偶的错误主要出在 Form1.Desinger.cs  中的那句中.....

希望各位大大们能给我提示，帮助偶解决这个问题...谢谢了.....
