Question

我是PowerShell的新手，我尝试自动创建DHCP预留。

到目前为止，我能够像这样获得IP地址：

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

返回如下字符串：

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＆＃39;

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
+                    ~~~
    + CategoryInfo          : InvalidData: (:) [Add-DhcpServerv4Reservation], ParameterBindingArgumentTransformationEx
   ception
    + FullyQualifiedErrorId : ParameterArgumentTransformationError,Add-DhcpServerv4Reservation

如何将字符串转换为System，.Net.IPAddress？

根据to this link，它应该很容易

> [ipaddress]"192.0.2.1"

然而，这不起作用。

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."
At line:1 char:1
+ $FOO = [IPAddress]$IP

Answer 1

[IPAddress]如果字符串中有空格

，则无法工作

使用Trim（）

删除它们

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

Answer 2

获取服务器IP地址的完全不同的方法是：

通过将工作站/服务器名称作为参数传递给输入类型System.Net.DNS cast

例如，如果主机的FQDN名称为ABCTest-DEV，则以下脚本将显示提供的ABCTest-Dev的IP地址，该主机在域中已经有DNS记录。

$ipaddr = [System.Net.Dns]::GetHostAddresses('ABCTest-Dev')|Where AddressFamily -EQ 'InterNetwork'
Write-Host 'This IPV4 Address of the Host is: '$ipaddr

Powershell将String转换为System.Net.IPAddress
