             this.Controls.Add(button1);

点击按钮不起作用

好的..所以，我们需要改进这意味着什么



你（例如）在这条线上放一个断点

ok .. so, we need to refine what that means

have you (for instance) put a breakpoint on this line

for (int i = 0; i < 50; i++)

in你的button1_Click处理程序，看看当你点击按钮程序控件是否转移到处理程序？



（提示：转到VS编辑器中提到的那一行，推送'F9'/功能键9，它应该变成红色）



如果你运行你的程序（例如使用CTRL-F5）它会跳转到那一行，然后显然是你需要查看的图表代码

in your button1_Click handler, to see if when you click the button program control gets transferred to the handler ?

(hint : go to that mentioned line in the VS editor, push 'F9'/Function Key 9, it should go red)

if when you run your program (use CTRL-F5 for instance) and it does jump to that line, then clearly its the graphing code that you need to look at
