实体框架4.1-刷新不是上下文的成员 [英] Entity Framework 4.1 - Refresh is not a member of Context

问题描述

我正在尝试使用Context.Refresh方法还原Context的更改，但是Refresh似乎不是Context的成员.

I'm trying to revert Context changes using the Context.Refresh method but It seems like Refresh is not a member of Context.

我正在使用Microsoft ADO.NET实体框架4.1 RC版本.

I'm using the Microsoft ADO.NET Entity Framework 4.1 RC version.

有什么主意吗?

推荐答案

您可能正在查看 IObjectContextAdapter 接口以获取基础的ObjectContext，然后在其上调用Refresh.

You are likely looking at a DbContext, which does not have a Refresh method. You can use the IObjectContextAdapter interface to get the underlying ObjectContext, and call Refresh on that.

var objectContext = ((IObjectContextAdapter)context).ObjectContext;
