EF渴望加载多个子子集合 [英] EF eager load multiple child child collections

问题描述

我似乎找不到如何急于在EF中加载多个子子集合的方法。所以我可以这样做：

I can't seem to find how to eager load multiple child child collections in EF. So I can do:

blawConext.Blaws
    .Include(b => b.ChildCollection
             .Select(cc => cc.ChildChildCollection)
     )

我甚至可以更深入没有问题，但是我无法获得umm同行？收集，以下内容不起作用

I can even go deeper and deeper without a problem but I can't get the umm peer? collection, The below does not work

blawConext.Blaws
    .Include(b => b.ChildCollection
             .Select(cc => cc.ChildChildCollection1)
             .Select(cc => cc.ChildChildCollection2)
     )

推荐答案

您可以指定多个包含项：

You can specify multiple includes:

blawConext.Blaws
    .Include(b => b.ChildCollection.Select(cc => cc.ChildChildCollection1))
    .Include(b => b.ChildCollection.Select(cc => cc.ChildChildCollection2))
