Forms 如何关闭主窗体并使用PowerShell调用另一个窗体？

我有两张表格。1是主窗体，2是子窗体。在主窗体中，我使用计时器和按钮。单击按钮后，将显示第二个窗体，主窗体将关闭。但我试过了，主窗体关闭了，但计时器仍在计数。因此，一旦计时器超时，第二个窗体将自动关闭。 我的期待一旦主形态，计时器也停止了。任何人都可以告诉我。多谢各位

这两个表单都被称为

$MainForm

，计时器将关闭

$MainForm

（

$MainForm.close（）

）。重命名第二个

$MainForm

将解决您的问题

但是，第二个

$MainForm

是在另一个函数中创建的，应该只存在于该函数的范围内。所以真正的问题是：为什么父作用域中的

$MainForm.Close（）

会关闭子作用域的

$MainForm
