powershell多用户输入分支

说到编程和powershell，我是个新手。我确实有很高的雄心壮志，所以我责成自己去创造一些比它本应该更困难的东西。到目前为止效果很好，但可能会更好

我的目标： 创建一个powershell脚本，该脚本将复制现有用户，以创建一个具有类似功能的新用户，该新用户具有一些类似的功能

脚本的功能如下：

询问管理员要复制哪个广告用户 请管理员命名新的广告用户 输出一些文字，然后在继续选择Y或N之前要求用户确认 如果管理员输入Y，则继续执行脚本。 如果管理员输入N，请重新启动脚本。 如果管理员输入了其他内容，请再次提问

我的问题： 如果管理员输入了错误的广告用户进行复制，而该用户不存在并抛出错误代码，我如何实现某种类型的错误检查？我希望控制台提醒他们这是错误的，并重新输入它

代码如下。如果您能提供任何完善建议，我们将不胜感激

PS：我刚开始使用powershell和一般的编码，所以我做了一些非常简单的事情，但是我学到了很多。我也计划清理代码。也许这段代码对那些正在寻找类似东西的人可能有用

回答您的问题：

try
{
    get-aduser $InputUser -Properties * -ErrorAction Stop
}
catch
{
    write-host $_.Exception.Message
}

imho powershell脚本旨在节省时间，并拥有尽可能少的读取主机

没错。这对我来说主要是一个实验。它有一些用处，但它不会节省我很多时间，也不会提高我的广告用户复制率。
