如何选择并单击Flowlayoutpanel中的第一个按钮，使用鼠标单击并且我不知道第一个按钮的名称，在运行时模式下

How Can I Select And Click The First Button In The Flowlayoutpanel With Out Mouse Clicking And I Don't Know The Name Of The First Button, In The Run Time Mode

推荐答案

使用WinForms按钮控件的'PerformClick方法[ ^ ]。



当然，表格应该显示（激活） ）在你打电话之前）。

Use the 'PerformClick method of the WinForms Button Control [^].

Of course, the Form should be shown (activated) before you call this).

请看我对问题和解决方案的评论1.



常规方法是抽象的来自处理程序的逻辑操作。这是通过编写实现所需效果的单独方法来完成的。这样，这个单独的方法可以从多个地方调用：从你单击处理程序和其他地方。



如果你有更具体的关注，你可以获得更详细的建议与你的代码相关。







另一个更具体的方法是利用a控制，或控制内部的选择。你不只是点击一个控件;点击可能会改变选择或聚焦。处理选择和聚焦事件可能需要一些副作用。然后，您可以通过编程方式更改聚焦或选择。

Please see my comment to the question and Solution 1.

The regular approach is abstracting of logical action from the handler. This is done by writing a separate method implementing the desired effect. This way, this separate method could be called from more than one place: from you click handler and elsewhere.

You can get more detailed advice if you have more specific concern related to your code.



Another, more specific approach is leveraging focusing of a control, or selection inside control. You don't just "click" on a control; the click may change selection or focusing. Handling selection and focusing event may need some side-effect action. And then, you can change focusing or selection programmatically.
