New-Object在PowerShell 2上失败，未找到构造函数错误

Question

下面的脚本在PowerShell 5上运行得很好

​

$NetworkChange = New-Object System.Net.NetworkInformation.networkchange

Register-ObjectEvent -InputObject $NetworkChange -EventName NetworkAddressChanged -SourceIdentifier "NetworkChanged" -Action {

    Write-Host "network switched"
    $LanConnected=@(Get-WmiObject win32_networkadapter -filter "netconnectionstatus = 2" | Where-Object {$_.netconnectionid -like "*Local Area Connection*"})

    If($LanConnected){
        Get-WmiObject win32_networkadapter -filter "netconnectionstatus = 2" | Where-Object {$_.netconnectionid -like "*Wireless Network Connection*"} | ForEach-Object {$_.disable()}
    }

    Else {
        Get-WmiObject win32_networkadapter | Where-Object {$_.netconnectionid -like "*Wireless Network Connection*"} | ForEach-Object {$_.enable()}
    }

}

​

但是，它在PowerShell 2上失败，并显示与New-Object cmdlet相关的以下错误

​

New-Object : Constructor not found. Cannot find an appropriate constructor for type System.Net.NetworkInformation.networkchange.
At line:1 char:11
+ New-Object <<<<  System.Net.NetworkInformation.networkchange
    + CategoryInfo          : ObjectNotFound: (:) [New-Object], PSArgumentException
    + FullyQualifiedErrorId : CannotFindAppropriateCtor,Microsoft.PowerShell.Commands.NewObjectCommand

​

知道它失败的原因吗？PowerShell 2上的New-Object cmdlet是否有不同的语法？

注意:我们的遗产仍然在PowerShell 2上，因此这场斗争。提前感谢
