EWS Managed API Demo: SearchFilterCollection

Hallo zusammen,

Wie SerachFilter funktionieren habe ich euch ja schon im vorhergehenden Artikel erklärt. Was wenn man aber nun mehr als nur ein Suchkriterium anwenden möchte? Dann nimmt man eine SearchFilterCollection.

Der relevante Code dazu ist untenstehend:

$SearchFilter1 = New-Object Microsoft.Exchange.WebServices.Data.SearchFilter+IsEqualTo([Microsoft.Exchange.WebServices.Data.EmailMessageSchema]::ItemClass, "IPM.Schedule.Meeting.Request")
$SearchFilter2 = New-Object Microsoft.Exchange.WebServices.Data.SearchFilter+IsEqualTo([Microsoft.Exchange.WebServices.Data.EmailMessageSchema]::ItemClass, "IPM.Schedule.Meeting.Resp.Pos")
$SearchFilter3 = New-Object Microsoft.Exchange.WebServices.Data.SearchFilter+IsEqualTo([Microsoft.Exchange.WebServices.Data.EmailMessageSchema]::ItemClass, "IPM.Schedule.Meeting.Resp.Tent")
$SearchFilter4 = New-Object Microsoft.Exchange.WebServices.Data.SearchFilter+IsEqualTo([Microsoft.Exchange.WebServices.Data.EmailMessageSchema]::ItemClass, "IPM.Schedule.Meeting.Resp.Neg")


$MySearchFilterCollection = new-object Microsoft.Exchange.WebServices.Data.SearchFilter+SearchFilterCollection([Microsoft.Exchange.WebServices.Data.LogicalOperator]::Or)
$MySearchFilterCollection.Add($SearchFilter1)
$MySearchFilterCollection.Add($SearchFilter2)
$MySearchFilterCollection.Add($SearchFilter3)
$MySearchFilterCollection.Add($SearchFilter4)
           
                            
$View = New-Object Microsoft.Exchange.WebServices.Data.ItemView(1000) 
$ExResult = $EWService.FindItems([Microsoft.Exchange.WebServices.Data.WellKnownFolderName]::Inbox,$MySearchFilterCollection,$View)

Und so sieht dann das ganze Script aus - kann ebenfalls heruntergeladen werden.

Und so sieht das Script dann in Powershell aus - man sieht, dass die verschiedenen MessageClasses gefunden worden sind.
