Question

I know I can include some foreign key objects in this way:

xx.Include(p=>p.xxId)

but I found that there’s another overload method has a parameter path.
I want to know what exactly I have to pass the value of the parameter.
Thanks for helping.

Answer 1

The navigational path.

Items.Include(item => item.Category)
Items.Include(item => item.Category.SubCategories)

is equivalent to

Items.Include("Category");
Items.Include("Category.SubCategories");
