Entity Collection

$

Hi Devs,

I have a simple fetch that retrieves [Opportunity Lines associated with Customer Asset ]. 

Question

How do i retrieve the [Customer Asset] fields in my for each loop in early bound.

try
{
string fetchQuery = @"
<fetch mapping='logical'>
<entity name='opportunityproduct' >
<attribute name='opportunityproductid' />
<filter type='and' >
<condition attribute='opportunityid' value='{zzz}' operator= 'eq'/>
</filter>
<link-entity name='msdyn_customerasset' alias='ap' link-type='inner' to='tac_customerlift' from='msdyn_customerassetid' >
<attribute name='tac_liftno' />
<attribute name='tac_liftid' />
</link-entity>
</entity>
</fetch>";

tracingService.Trace("Retrieved FetchXML Query");
fetchQuery = fetchQuery.Replace("zzz", OpportunityID.ToString());
EntityCollection results = service.RetrieveMultiple(new FetchExpression(fetchQuery));

// Run the query with the FetchXML
try
{
if (results.Entities.Count > 0)
foreach (var opportunitylines in results.Entities)
{
OpportunityProduct opplines = opportunitylines.ToEntity<OpportunityProduct>();
msdyn_customerasset CustAssett = opportunitylines.ToEntity<msdyn_customerasset>();    // Do i need to add Customer Asset to the entity collection just after the fetch ?

opplines.tacagreement = AgreementReference;
CustAssett.tac_flag = true;
CustAssett.tac_LiftID = "updated";
