Linq-to-Sql LoadWith返回null

Question

In my code I have this:

DataLoadOptions dlo = new DataLoadOptions();
dlo.LoadWith<Place>(p => p.Address);
context.LoadOptions = dlo;

var places = context.Places.Where(p => p.ID >= 100 && p.ID <= 200);

The problem is the Address returned is null and I don't know why.
