Powershell help

Hi, am running following powershell script, and I ran into an error.

Add-PSSnapin Microsoft.Sharepoint.PowerShell


$MyWeb = Get-SPWeb "http://MySite"
$MyList = $MyWeb.Lists["MyList"]
$exportList = @()
$MyList.Items | foreach{
$obj = New-Object PSObject -Property @{
    "ID" = $_["ID"]
     "Content Type" = $_["P. Type"]
     "Program Name" = $_["Program Name"]
     "Classifications" = ($_["Classifications"]).substring(($_["Classifications"]).IndexOf("#")+1)
     "Classifications ID" = ($_["Classifications"]).split(";")[0]
     
       
}

 
  $exportList += $obj
  $exportlist | Export-Csv -Path "\\MyServer\MyLocation\MyExport.csv"

}

Error: Export-CSV : Cannot bind argument to parameter ‘InputObject’ because it is null.

The error is that    $exportlist | Export-Csv -Path "\\MyServer\MyLocation\MyExport.csv" needs to be outside of the foreach. But the code Subsun showned is better, not using any intermediate variables.
