我是英孚的新手的话，对不起，我也许愚蠢的问题。

我有2实体没有任何关系（VS不会加载加入，我不能手动添加，因为孩子的主键使用其父的推导键）。

示例

实体主 产品 键GKey_K，Product_K 域.....

实体的细节 GenericInformation 键GKey_K，GI_K 田Product_K，......

好了，我的问题很简单（我也希望我的英语！），我怎么能只读那些对GenericInformation一些参考的产品？

TIA

EXISTS 在SQL〜= 任何的LINQ：

 变种Q =从p在Context.Products
        其中，Context.GenericInformation.Any（GI =＆GT; gi.Product_K == p.Product_K）
        //添加其他列的地方，如果需要的话;我不能告诉是什么
        //关系被认为是
        选择磷;
 

I'm a rookies of EF so, sorry for my perhaps foolish question.

I've 2 entities without any relationship (VS does not load the join and I can't manually add it because the primary key of the child uses a derivated key of its parent).

Example

Entity master Products keys GKey_K, Product_K fields .....

Entity detail GenericInformation keys GKey_K, GI_K fields Product_K, ....

Well, my question is simple (I hope also my english!), how I can read only the products that have some reference on GenericInformation?

TIA

EXISTS in SQL ~= Any in LINQ:

var q = from p in Context.Products
        where Context.GenericInformation.Any(gi => gi.Product_K == p.Product_K)
        // add other columns to the where if need be; I can't tell what the 
        // relationship is supposed to be
        select p;
