Powershell将字符串转换为System.Net.IPAddress [英] Powershell convert String to System.Net.IPAddress

问题描述

我是PowerShell的新手，我正在尝试自动创建DHCP保留.

I'm new to powershell and I'm trying to automate creating a DHCP reservation.

到目前为止，我已经可以像这样获得IP地址:

So far I'm able to get the IP address like so:

$IP = ( GEt-VM -ComputerName $HVCOMPUTERNAME -VMName $HVNAME | Get-VMNetworkAdapter).IpAddresses[0]

这将返回一个字符串，如:

This returns a string like:

192.0.2.1

但是，Add-DhcpServer4Resrvation cmdlet不接受IP地址作为字符串.它要求IP地址为"System.Net.IpAddress"

However, the Add-DhcpServer4Resrvation cmdlet does not accept an ip address as a string. It requires the IP address be a 'System.Net.IpAddress'

Add-DhcpServerv4Reservation -ComputerName $DHCPServer -ScopeId $DHCPScope -IPAddress $IP -Client
Id $MacAddress -Name $HVNAME

Add-DhcpServerv4Reservation : Cannot process argument transformation on parameter 'IPAddress'. Cannot convert value "
10.254.130.104
" to type "System.Net.IPAddress". Error: "An invalid IP address was specified."
At line:1 char:86
+ ... ope -IPAddress $IP -ClientId $MacAddress -Name $HVNAME
+                    ~~~

如何将字符串转换为System.Net.IPAddress?

根据到此链接，它应该很容易

> [ipaddress]"192.0.2.1"

但是那行不通.

PS C:\Windows\system32> $FOO = [IPAddress]$IP
Cannot convert value "
10.254.130.104
" to type "System.Net.IPAddress". Error: "An invalid IP address was specified."

推荐答案

[IPAddress]如果字符串中有空格，则无法正常工作

[IPAddress] Wont work if there are spaces in the string

使用Trim()删除它们

Remove them with Trim()

$IP = [IPAddress]$IP.Trim()
