推荐答案

你可以迭代控制集合。

You can iterate through control collection.

foreach (Control control in Controls)
{
      Button button = control as Button;
      if (!ReferenceEqual(null, button))
      {
        button.Visible = someConditionIfYoWant;
      }
}

如果您试图直接在窗口代码中找到按钮，您只需参考按钮按它的名字。 WinForms中的所有控件都有一个名称，所以如果你的按钮被称为 button1 ，那么访问按钮以查看可见性只是 button1.Visible



如果它来自窗外，您可能需要将按钮更改为公开。

If you're trying to find the button directly in the code of your window you can just reference the button by it's name. All controls in WinForms are given a name, so if your button has been called button1 then accessing the button for visibility is just button1.Visible

If it's from outside the window you may need to change your button to be public.
