SerializableObjectLayerServiceClient Class

A distributed object access layer (an ISerializableObjectLayer implementation) for client applications transferring data via WCF.

Namespace: DevExpress.Xpo.DB

Assembly: DevExpress.Xpo.v24.1.dll

NuGet Packages: DevExpress.Win.PivotGrid, DevExpress.Win.TreeMap, DevExpress.Xpo

NuGet Package: DevExpress.Xpo

Declaration

C#

public class SerializableObjectLayerServiceClient :
    SerializableObjectLayerServiceClientBase<ISerializableObjectLayerService>

VB.NET

Public Class SerializableObjectLayerServiceClient
    Inherits SerializableObjectLayerServiceClientBase(Of ISerializableObjectLayerService)

Remarks

Normally, all you have to do is initialize a SerializableObjectLayerServiceClient with a service endpoint in the client application, as shown below.

C#

// (ObjectWcfClient.cs)
class Program {
    static void Main(string[] args) {
        // Creating a distributed object layer based on data retrieved via a WCF service.
        // The service endpoint is obtained from the client application's App.config file.
        ISerializableObjectLayer serializableObjectLayer = new 
            SerializableObjectLayerServiceClient("BasicHttpBinding_ISerializableObjectLayerService");

        // Checking connection.
        serializableObjectLayer.CanLoadCollectionObjects.ToString();

        XpoDefault.DataLayer = null;
        XpoDefault.Session = null;
        // Instantiates an object access layer used to retrieve and update object data 
        // in a data store exposed via a WCF service.
        ObjectHelper.ObjectLayer = new SerializableObjectLayerClient(serializableObjectLayer);

        using(UnitOfWork uow = new UnitOfWork(ObjectHelper.ObjectLayer)) {
            // Object data manipulations.
            // ...
        }
    }
}
public static class ObjectHelper {
    public static IObjectLayer ObjectLayer;
}

VB.NET

' (ObjectWcfClient.vb)
Friend Class Program
    Shared Sub Main(ByVal args() As String)
        ' Creating a distributed object layer based on data retrieved via a WCF service.
        ' The service endpoint is obtained from the client application's App.config file.
        Dim serializableObjectLayer As ISerializableObjectLayer = New _
        SerializableObjectLayerServiceClient("BasicHttpBinding_ISerializableObjectLayerService")

        ' Checking connection.
        serializableObjectLayer.CanLoadCollectionObjects.ToString()

        XpoDefault.DataLayer = Nothing
        XpoDefault.Session = Nothing
        ' Instantiates an object access layer used to retrieve and update object data 
        ' in a data store exposed via a WCF service.
        ObjectHelper.ObjectLayer = New SerializableObjectLayerClient(serializableObjectLayer)

        Using uow As New UnitOfWork(ObjectHelper.ObjectLayer)
            ' Object data manipulations.
            ' ...
        End Using
    End Sub
End Class
Public NotInheritable Class ObjectHelper
    Public Shared ObjectLayer As IObjectLayer
End Class
