How map single entity with multiple table

Question

I want to get data from two tables with single Entity class. How??

public class HomeViewModel  
{ 
    [Key] 
    [Column(\"candidate_ID\")] 
    public int cand         


        

Answer 1

If you are suggesting that Table2 merely holds a foreign key to table1, but has a different primary key, then you can't really do what you're asking. Simply holding a foriegn key means that's a one to many relationship, and there's no way to map a single entity across a one to many relationship like that (even if your data only contains one record, the model relationship type is still one to many)

If you mean that Table2 has a primary and foreign key of candidate_id (and thus it's a 1 to 1 mapping) then you can map them into a single entity fairly easily using Inheritence described here:

If all you want is to create a single object that contains data from two tables, then that's a relatively simple linq query, which i won't get into because I really don't know exactly what you're looking for here.
