Lambda表达式：如何从一个查询中选择两个不相关的表

Question

你能帮我用lambda表达式重写这个查询语法吗？

(From Entity.Apple a in db.Context.Apples
From Entity.Bikini b in db.Context.Bikinis
Where a.Id== 10
Where b.Id== 15
Select new {NaturalColor: a.Color, FavoriteColor: b.Color }).FirstOrDefault();

我尝试查找两个不相关的表的特定记录，一个连接。在我的例子中，下一步可能是：

FindColorDiffrent(Naturalcolor, FavoriteColor){}

Answer 1

db.Context.Apples
  .SelectMany(a => db.Context.Bikinis, (a, b) => new {a, b})
  .Where(x => x.a.Id == 10)
  .Where(x => x.b.Id == 15)
  .Select(x => new {NaturalColor: x.a.Color, FavoriteColor: x.b.Color })
  .FirstOrDefault();
