【问题描述】：
当创建一个表单并希望通过单击该表单上的按钮进行导航时，是否需要创建一个全新的表单才能打开下一页？或者当前表单是否可以通过其他按钮以某种方式重新初始化？
单击“Active Directory”按钮时，您可以看到表单正在重新加载或重新绘制自身。由于我对此并没有真正的经验，并且很难找到有关表单内导航的信息，如果有人能告诉我这是否是正确执行此操作的方法，那就太好了？
因为每次进入菜单时，您都需要创建一个全新的表单，以便为错误留出空间，因为您想要的东西（例如“无法最大化”、图标、标题栏、退出按钮、后退按钮、. ..') 在不同的窗口中都相同。
对于第二个窗口，“Active Directory”，我尝试了StartPosition = 'CenterParent' 之类的方法，但这不起作用，因为它出现在一个完全不同的位置，然后它的父级已关闭。
感谢您的帮助。

虽然这一切都可以使用 PowerShell，但我想知道您是否应该使用 Visual Studio 和适当的表单设计器来执行此操作，因为这听起来相当复杂。在这种情况下，我认为最好在一个表单中拥有多个面板，您可以在导航期间显示/隐藏这些面板

谢谢arco444，我刚刚找到this 作为如何使用面板的示例。我仍在试图弄清楚。与此同时，我也在查看 Visual Studio，看看使用此工具是否更容易创建正确的表单。
