LINQ - i want to retrive tha data from two table

var qry = from c in drop.tblStudentDetails  join s in drop.tblStudentAddresses on   c.AddressId   equals s.Id select new { c.Id, s.Address };

for one table i have return it but i want to retrive one details fro another table

In this codition  { c.Id, s.Address }; you are already selecting data from Two tables

what else you need??

You seem to be using the right tables. But not quite sure what is it that you seem to be missing. 

And Instead of Join, you could do this:
var qry = 
from c in drop.tblStudentDetails
from s in drop.tblStudentAddresses
where(c.AddressId   equals s.Id)
select new { c.Id, s.Address };

I also believe that you are joining on the wrong fields (adressid and student id?). 

sir this was the one query that i have join but in that same  table i wanna to joinone more table that in my table i haver one column as studentid in one table and in another table student name is there that i wanna to retrive...........

Please explain some more.
