Powershell取消按钮不具有呼叫功能

Question

我有创建带复选框弹出窗口的脚本。

如果选中复选框并按下确定，则$ districtArray [1]为True

BUT

如果选中复选框并按下CANCEL，则$ districtArray [1]也为真

我希望CANCEL按钮会使整个$ districtArray为FALSE。

因此，当单击CANCEL时，我包含了函数initArray

$CancelButton.Add_Click({initArray; $Form.Close()})

这是完整的脚本供参考

$i = $NULL
$districtArray = @()
$highestDistrict = 33




function initArray{
    for ($i = 0; $i -lt $highestDistrict; $i++) 
    { 
       $script:districtArray += @($false) 
    }


}
