实体框架 6 Create() 与新

Entity Framework 6 Create() vs new(实体框架 6 Create() 与新)

问题描述

这两种方式添加实体有什么区别?

What is the difference between adding an entity in these two ways?

MyEntity me = new MyEntity();
entities.myentities.Add(me);

对

MyEntity me = entities.myentities.Create();

我还需要在第二个示例中添加我"吗?如果是这样，是否有某种优势，一种方式或另一种方式?

Do I still need to add "me" in the second example? If so, is there some sort of advantage, one way or the other?

非常感谢！

推荐答案

MyEntity me = new MyEntity();

将创建一个新的 MyEntity

MyEntity me = entities.myentities.Create();

将创建 MyEntity 的代理包装实例(假设您的上下文配置为创建代理)

will create a proxy wrapped instance of MyEntity (assuming your context is configured to create proxies)

此代理覆盖实体的一些虚拟属性以插入挂钩，以便在访问属性时自动执行操作.例如，该机制用于支持关系的延迟加载.

This proxy overrides some virtual properties of the entity to insert hooks for performing actions automatically when the property is accessed. For example, this mechanism is used to support lazy loading of relationships.
