问题在于循环 DoUntil。脚本必须获取 URL，然后询问如何处理他并在用户选择数字（1-4）后给出结果，然后输出再次给出菜单，用户可以根据需要选择另一个数字或完成脚本输入“X”。

但是这个脚本以不同的方式工作，它是询问 URL，在我选择号码之后，然后它再次询问 URL 和号码，然后（例如，如果我将选择两次相同的号码）它将为我带来 2 个 URL 的值。

请指教，我做错了什么。

write-host ""
write-host "Past URL that you need to check"
write-host ""
write-host -nonewline "Type your URL and press Enter: "
$URLok = read-host
write-host ""

if ($URLok.Length -lt 1) {
    write-host "Invalid selection"
}

do {
    write-host "What do you want to do with this URL?"
    write-host ""
    write-host "DNS - Selection 1"
    write-host " MX - Selection 2"
    write-host " NS - Selection 3"
    write-host "TXT - Selection 4"
    write-host ""
    write-host "X - Exit"
    write-host ""
    write-host -nonewline "Type your choice and press Enter: "

    $choice = read-host

    $ok = $choice -match '^[1234x]+$'

    if ( -not $ok) {
        write-host "Invalid selection"
    }

    switch -Regex ( $choice ) {
        "1"
        {
            [System.Net.Dns]::resolve($URLok)
        }

        "2"
        {
            Resolve-DnsName -Name $URLok -Type MX -DnsOnly | select Name,Type,NameExchange
        }

        "3"
        {
            Resolve-DnsName -Name '888ladies.com' -Type NS -DnsOnly | select Name,Type,NameHost,PrimaryServer

        }

        "4"
        {
            Resolve-DnsName -Name $URLok -Type TXT | select Name,Type,Strings
        }

        "5"
        {
            write-host ""
            write-host "Past URL that you need to check"
            write-host ""
            write-host -nonewline "Type your URL and press Enter: "
            $URLok = read-host
            write-host ""
        }
    }
} while($choice -ne "X")

Ps 和一点评论，在 2-3-4 选项中我有 ' Resolve-DNSName' 但是这个脚本不会在循环doUntil完成之前在控制台上显示它。所以只有当我选择'X'并完成循环时我才能看到结果

答案是点子Format-Table，它的工作！

例如：

Resolve-DnsName -Name $URLok -Type NS -DnsOnly | select Name,Type,NameHost,PrimaryServer| Format-Table
