title: How to use LINQ to query from a list of objects into an existing object?
body: <p>I'm not sure if this is possible in LINQ, but I have the following scenario:</p>
  
  <p>I'm calling a SharePoint list service multiple times with multiple queries. I am then populating a single object and its properties from all of the queries.  I am using LINQ to query the XElement returned.  I know that if the call gets to this point, that there will only ever be one item returned from my LINQ query.  I currently have to query into a new object and then set the properties of my main object from this new object (from LINQ), for each web service call. (The below code sample contains only a small portion of the 'Action' item properties that would need to be queried and set.)</p>
  
  <p>Is there any way to make the below statement 'select' into my existing 'action' object?</p>
  
  <pre><code>var item = (from listItem in result.GetSPListItems()
              select new ContractAction
              {
                  Title = listItem.GetSPFieldValue("Title"),
                  Description = listItem.GetSPFieldValue("Description"),
                  DeliveryOrderID = SPHelper.GetFirstLookupID(listItem.GetSPFieldValue("Delivery Order")),
                  EstimatedValue = ((listItem.GetSPFieldValue("Estimated Value") as double?) ?? 0),
                  AgreementTypeID = SPHelper.GetFirstLookupID(listItem.GetSPFieldValue("Contract Type")),                                                
              }).FirstOrDefault();
  
  contractAction.Title = item.Title;
  contractAction.Description = item.Description;
  contractAction.DeliveryOrderID = item.DeliveryOrderID;
  contractAction.EstimatedValue = item.EstimatedValue;
  contractAction.AgreementTypeID = item.AgreementTypeID;
  </code></pre>
