Powershell 脚本中的多个错误（用于更改 NIC 设置）

Question

我是 Powershell 脚本的新手，因此非常感谢每一位帮助。 我整理了一个脚本（主要来自 Parts 和我认为可行的脚本）来从多项选择菜单更改 IP 地址，它似乎有点工作，但在选择选项时会引发多个错误。

function Find-Adapter() {
    return Get-NetAdapter -Physical | Where-Object {$_.Status -eq "up"}
}

function Set-ManualIP($IP, $MaskBits, $Gateway, $Dns, $IPType) {
        # Retrieve the network adapter that you want to configure
            $adapter = Find-Adapter

        # Remove any existing IP, gateway from our ipv4 adapter
        If (($adapter | Get-NetIPConfiguration).IPv4Address.IPAddress) {
             $adapter | Remove-NetIPAddress -AddressFamily $IPType -Confirm:$false
}
        If (($adapter | Get-NetIPConfiguration).Ipv4DefaultGateway) {
             $adapter | Remove-NetRoute -AddressFamily $IPType -Confirm:$false
}
        # Configure the IP address and default gateway
             $adapter | New-NetIPAddress `
                        -AddressFamily $IPType `
                        -IPAddress $IP `
                        -PrefixLength $MaskBits `
                        -DefaultGateway $Gateway

        # Configure the DNS client server IP addresses
             $adapter | Set-DnsClientServerAddress -ServerAddresses $DNS
}

Errors when Script runs on a VM

Answer 1

删除 cmets # This means subnet mask = 255.255.255.0 这似乎是网关、dns 和 iptype 未传递给函数 Set-ManualIP 的问题。
