WCF Web api 和带有 odata 的复杂类型
我正在使用 WCF Web api 来 bui;da 休息服务，该服务从 odata 查询返回复杂对象。不幸的是，查询复杂类型似乎不起作用。 EG
public IQueryable<Person> Get()
{
var people = new List<Person>()
{
new Person {
Name="John",
Department = new Department{Id=2, Description="Lion Swaddling"}
},
new Person {
Name="Jane",
Department = new Department{Id=4, Description="Face Surgery"}
},
};
return people.AsQueryable();
}
以下 uri 不返回任何内容。 http://localhost/api/people?$filter=Department/Id%20eq%20'2'
是否Web Api，其实支持查询复杂类型？如果是这样，我必须做一些特殊的事情才能启用它吗？
I'm using WCF web api to bui;d a rest service that returns coplex objects from an odata query. Unfortunately, querying complex types doesn't seem to work. E.G.
public IQueryable<Person> Get()
{
var people = new List<Person>()
{
new Person {
Name="John",
Department = new Department{Id=2, Description="Lion Swaddling"}
},
new Person {
Name="Jane",
Department = new Department{Id=4, Description="Face Surgery"}
},
};
return people.AsQueryable();
}
The following uri returns nothing.
http://localhost/api/people?$filter=Department/Id%20eq%20'2'
Does the Web Api, in fact, support querying complex types? And if so, is there something special i must to to enable it?

已解决：原来我的一些对象具有空描述值。一旦我确定所有的东西都有价值，它就可以正常工作。
Resolved: Turns out some of my objects had null Description values. Once i made sure all had values it worked fine.
