Question

应该很简单但是不能弄清楚逻辑。下面是我目前拥有哪种工作方式的代码，但是唯一的问题是，如果选中了多个复选框，并且您取消选中了禁用的按钮，只要选中了一个或多个复选框，我就需要保持按钮处于启用状态。我还尝试了各种复杂的If和Elseif语句，但是我没有尝试过更改此行为。

[void]$Form.ShowDialog()

我会做这样的事情：

$Form.controls.AddRange(@($MonCheckBox, $TueCheckBox, $WedCheckBox, $ThuCheckBox, $FriCheckBox, $SchedButton))

Function Test-AnyButtonChecked {
    if (
        $MonCheckBox.Checked -or
        $TueCheckBox.Checked -or
        $WedCheckBox.Checked -or
        $ThuCheckBox.Checked -or
        $FriCheckBox.Checked
    ) {
        $SchedButton.Enabled = $true
    }
    else {
        $SchedButton.Enabled = $false
    }
}

$MonCheckBox.add_CheckedChanged( { Test-AnyButtonChecked })
$TueCheckBox.add_CheckedChanged( { Test-AnyButtonChecked })
$WedCheckBox.add_CheckedChanged( { Test-AnyButtonChecked })
$ThuCheckBox.add_CheckedChanged( { Test-AnyButtonChecked })
$FriCheckBox.add_CheckedChanged( { Test-AnyButtonChecked })

[void]$Form.ShowDialog()

PowerShell WinForm：如果选中了一个或多个复选框，则启用按钮，否则禁用按钮
