将$ myVar设置为带通配符的变量

Question

I have the below script which I had help with from here, one quick question how do you I set $MyVar as variable, and a wildcard so partial name can be selected.

Select-AzureRmSubscription -SubscriptionName "MySubscription"
Get-AzureRmResourceGroup | Where-Object {$_.ResourceGroupName -like '$MyVar'} | ForEach-Object {
    $VMs = Get-AzureRmVM -ResourceGroupName $_.ResourceGroupName
    ForEach ($vm in $vms) {
        $tags2 = $VM.tags
        $tags2 += @{ShutdownSchedule_AllowStart="True"; ShutdownSchedule_AllowStop="True" }

        Set-AzureRmResource -ResourceName $vm.Name -ResourceGroupName $vm.ResourceGroupName -ResourceType "Microsoft.Compute/virtualMachines" -Tag $tags2 -Force -Verbose
    }
}

Not sure how to set it as a variable. Was thinking maybe {$_.ResourceGroupName -like $('$MyVar')}

Or do I need to set it as a parameter, as in a workflow, but not sure how to do that outside a workflow..

使用双引号使变量可以扩展（请参阅about_quoting_rules ），然后在要通配的任一端（或两端）加* ：

{$_.ResourceGroupName -like "*$MyVar*"}
