Powershell-如何使用下拉菜单进行实时Active directory搜索

Question

对于像你这样有经验的人来说，这可能是一个简单的问题，但我如何在Active Directory中实时搜索下拉菜单中的用户名？将所选结果并将值传递给$var

这是我的from和我的两个下拉菜单，我希望manager下拉菜单根据我输入的字符串在我的Active Directory中进行查找。也就是说，如果我输入Macdonald，下拉项将显示我的广告中的所有麦当劳的名字或姓氏。

要进行实时更新，需要在修改下拉框中的文本时更新列表。当您在其中写入时，至少会触发两个事件：TextUpdate和KeyPress。选择一个。我建议TextUpdate，因为它在文本更改后会做出反应，而KeyPress在更改前会做出反应。您可以使用例如：添加事件侦听器

$DropDown2.add_TextUpdate({ Write-Host "TextUpdate. Updated text is: $($Dropdown2.Text)" })

在脚本块中，您需要运行一个查询DC的函数，但这个问题没有用ADSI、AD、LDAP等标记，所以这是另一个问题。

请注意每次更改导致DC额外负载的信件时，都会运行查询。例如，如果你想写"Mark"，在你写完之前，它至少搜索了4次。

我建议使用带有搜索按钮的文本框，以尽量减少不必要的流量。
