I have entity instance(north)
我有实体实例（北）
NorthdatabaseEntity north = new NorthdatabaseEntity()
The problem is that i don't have access to ObjectContext methods. I tried to call them with object "north" but i didn't found the method "AddObject" or any other from ObjectContext. I thought that any entity object has all methods from ObjectContext class.
问题是我无法访问ObjectContext方法。我试图用对象“north”调用它们，但我没有找到方法“AddObject”或ObjectContext中的任何其他方法。我认为任何实体对象都有ObjectContext类的所有方法。
Where is the problem here?
这里的问题在哪里？

ObjectContext and entities are different objects; you may use ObjectContext to add/modify/delete objects, but entities does not have direct access to ObjectContext.
ObjectContext和实体是不同的对象;您可以使用ObjectContext添加/修改/删除对象，但实体不能直接访问ObjectContext。
You need to create an instance of ObjectContext and perform your operations on itself, not on entities.
您需要创建ObjectContext的实例并对其自身执行操作，而不是对实体执行操作。
