Saving and using association View

Hello together
I am using the below function, i can save the association view to an xml file via the Client.Objects.Save method but not able to read and use it again. Has anyone had any luck with this or can help me out ?

public void GetAssociationView(bool useCache)
{
if (useCache)
{
string path = GetCacheName();
List<Type> extraTypes = new List<Type>(Gurux.DLMS.GXDLMSClient.GetObjectTypes());
extraTypes.Add(typeof(GXDLMSAttributeSettings));
extraTypes.Add(typeof(GXDLMSAttribute));
XmlSerializer x = new XmlSerializer(typeof(GXDLMSObjectCollection), extraTypes.ToArray());
//You can save association view, but make sure that it is not change.
//Save Association view to the cache so it is not needed to retrieve every time.
if (File.Exists(path))
{
try
{
using (Stream stream = File.Open(path, FileMode.Open))
{
Console.WriteLine("Get available objects from the cache.");
Client.Objects.AddRange(x.Deserialize(stream) as GXDLMSObjectCollection);
stream.Close();
}
return;
}
catch (Exception ex)
{
if (File.Exists(path))
{
File.Delete(path);
}
throw ex;
}
}
}
GXReplyData reply = new GXReplyData();
ReadDataBlock(Client.GetObjectsRequest(), reply);
Client.ParseObjects(reply.Data, true);
}
