MVC - Linq to SQL JOINS - asp.net-mvc

Question

I have a controller that accepts a list of strings. THese strings essentially are IDs that a user selects on the view. I need to build the model based upon fields from to tables, hence the need for the join. The bellow code will not build as it claims the properties from the joined table do not exist. It only accepts table 1 values. Item.Well_No and Item.Well_Name throw the error. These are included in the "y" table that i joined to "x"..
[HttpPost]
public ActionResult buildSelectionTable(List<string> dta)
{
var a = from x in db._AGREEMENTS
join y in db.WELL_AGMT_XREF on x.AGMT_NUM equals y.AGMT_NUM
where dta.Contains(x.AGMT_NUM)
select x;
List<AgmtModel> model = new List<AgmtModel>();
foreach (var item in a)
{
model.Add(new AgmtModel { Agmt_Name = item.AGMT_NAME, Agmt_Num = item.AGMT_NUM, Agmt_Type = item.AGMT_TYPE_DESCR, Amnt_Status = item.AGMT_STAT_DESCR, Company = item.CO_NAME, DaysToExp = item.DaysToExp, Drs_Url = item.DRS_URL, Effective_Date = item.EFF_DT, Orig_Lessee = item.ORIG_LESSEE, Prop_Status = item.AGMT_PROP_STAT_DESCR, Expiration_Date = item.EXPR_DATE, Acreage = item.LGL_AREA, Extention_Expiration = item.EXTN_EXPR_DT, WellNo = item.WELL_NO, Well_Name = item.WELL_NAME });
}
return PartialView("_SelectionTable", model);
}

Answer 1

You are only selecting x in your query you need to also select y and reference it.
change select x to be select new { x, y}
and then
foreach (var item in a)
{
model.Add(new AgmtModel { Agmt_Name = item.y.AGMT_NAME, Agmt_Num = item.x.AGMT_NUM ... });
}
you need to insert .x or .y before you the field to determine the field names
alternatively you could actually put the constructor directly in the query
so instead of select x
select new AgmtModel { Agmt_Name = y.AGMT_NAME, etc...}
then you can just return PartialView("_SelectionTable", a.ToList())
