powershell - Select option from Array

Question

I am working on a side project and to make it easier for managment since almost all of out server names are 15 charactors long I started to look for an RDP managment option but none that I liked; so I started to write one and I am down to only one issue, what do I do to manage if the user types not enough for a search so two servers will match the Query. I think I will have to put it in an array and then let them select the server they meant. Here is what I have so far

function Connect-RDP
{

param (
    [Parameter(Mandatory = $true)]
    $ComputerName,
    [System.Management.Automation.Credential()]
    $Credential
)

# take each computername and process it individually
$ComputerName | ForEach-Object{
    Try
    {
        $Computer = $_
        $ConnectionDNS = Get-ADComputer -server "DomainController:1234" -ldapfilter "(name=$computer)" -ErrorAction Stop | Select-Object -ExpandProperty DNSHostName
        $ConnectionSearchDNS = Get-ADComputer -server "DomainController:1234" -ldapfilter "(name=*$computer*)" | Select -Exp DNSHostName            
        Write-host $ConnectionDNS
        Write-host $ConnectionSearchDNS
        if ($ConnectionDNS){
        #mstsc.exe /v ($ConnectionDNS) /f
        }Else{
        #mstsc.exe /v ($ConnectionSearchDNS) /f
        }
    }
    catch
    {
        Write-Host "Could not locate computer '$Computer' in AD." -ForegroundColor Red
    }
}
}

Basically I am looking for a way to manage if a user types server1

that it will ask does he want to connect to Server10 or Server11 since both of them match the filter.

Another option for presenting choices to the user is Out-GridView, with the -OutPutMode switch.

Borrowing from Matt's example:

$selection = Get-ChildItem C:emp -Directory

If($selection.Count -gt 1){
   $IDX = 0
   $(foreach ($item in $selection){
   $item | select @{l='IDX';e={$IDX}},Name
   $IDX++}) |
   Out-GridView -Title 'Select one or more folders to use' -OutputMode Multiple |
   foreach { $selection[$_.IDX] }
 }

 else {$Selection}   

This example allows for selection of multiple folders, but can you can limit them to a single folder by simply switching -OutPutMode to Single
