LINQ to SQL的加入對多列使用lambda

Question

有人可以幫我翻譯這個

var query = from s in context.ShoppingMalls 
join h in context.Houses 
on 
new { s.CouncilCode, s.PostCode } 
equals 
new { h.CouncilCode, h.PostCode } 
select s; 

入λ查詢？

謝謝。

Answer 1

var query = context.ShoppingMalls 
        .Join(
         context.Houses, 
         s => new { s.CouncilCode, s.PostCode }, 
         h => new { h.CouncilCode, h.PostCode }, 
         (s, h) => s);
