Read the push object list

Hi

I want to read push object list by using this code

GXDLMSPushSetup push = new GXDLMSPushSetup("0.0.25.9.0.255",3);

GXDLMSPushSetup clone = (GXDLMSPushSetup)push;

clone.GetPushValues(client, (List<object>)notify.Value);

foreach (KeyValueP<GXDLMSObject, GXDLMSCaptureObject> it in clone.PushObjectList)
{
int index = it.Value.AttributeIndex - 1;
Console.WriteLine(((IGXDLMSBase)it.Key).GetNames()[index] + ": " + it.Key.GetValues()[index]);
}

but it is giving error "Size of the push object list is different than values". could please help me in this.

Thanks
