问题描述

ObjectContext.GetObjectType 方法应该返回与指定类型的代理对象关联的POCO实体的实体类型"

The ObjectContext.GetObjectType Method should return "the entity type of the POCO entity associated with a proxy object of a specified type"

那么我的代码怎么只返回代理呢?

So how come in my code it just returns the proxy?

我正在使用实体框架 6 候选版本

I am using entity framework 6 release candidate

        //Soft delete
        var e = Context.Set<T>().Find(id);
        e.IsDeleted = true;
        InsertOrUpdate(e);

        Type t = System.Data.Objects.ObjectContext.GetObjectType(e.GetType());
        string name = t.Name;
        //Property_6C887DE7274181E6E99D6FCF2C21BDD59E226F99B0064F59954E70062C135331

        //Surely I shouldn't have to use Substring here?
        name = name.Substring(0, name.IndexOf("_")).ToSpacedTitleCase();
        string message = name + " deleted";

推荐答案

你使用了错误的 ObjectContext.EF6 不是基于 System.Data.Entity.dll 构建的.您需要使用 EntityFramework.dll 中的 ObjectContext.如果您使用 EF6 来避免这种情况，实际上不建议在您的项目中引用 System.Data.Entity.dll.

You are using the wrong ObjectContext. EF6 is not built on System.Data.Entity.dll. You need to use ObjectContext from EntityFramework.dll. It's actually not recommended to have a reference to System.Data.Entity.dll in your project at all if you are using EF6 to avoid situation like this.

解决您的问题:

• 删除对 System.Data.Entity.dll 的引用(以防万一)
• 将 System.Data.Objects.ObjectContext.GetObjectType(e.GetType()); 替换为 System.Data.Entity.Core.Objects.ObjectContext.GetObjectType(e.GetType())
