实体框架查询结果

Question

我正在使用EntityFramework 4.3.1并尝试运行像这样的查询

Context.Set<KullaniciYetkiView>().Where(y => y.KullaniciId == kullaniciId && y.YetkiKod == yetkiKod)

当我运行查询并按预期返回115条记录时。但是当我看到记录时，所有这些都是一样的。所以我从分析器中搜索查询以查看我缺少的内容，是查看以下查询并从管理工作室返回115条不同的记录。

exec sp_executesql N'SELECT 
[Extent1].[YetkiKod] AS [YetkiKod], 
[Extent1].[KullaniciId] AS [KullaniciId], 
[Extent1].[LokasyonId] AS [LokasyonId], 
[Extent1].[YetkiId] AS [YetkiId], 
[Extent1].[HiyerarsikKod] AS [HiyerarsikKod], 
[Extent1].[LokasyonSeviye] AS [LokasyonSeviye], 
[Extent1].[Yetkili] AS [Yetkili], 
[Extent1].[Engelli] AS [Engelli], 
[Extent1].[LokasyonEngelli] AS [LokasyonEngelli]
FROM [dbo].[sayKullaniciYetkiView] AS [Extent1]
WHERE ([Extent1].[KullaniciId] = @p__linq__0) AND ([Extent1].[YetkiKod] = @p__linq__1)',N'@p__linq__0 uniqueidentifier,@p__linq__1 nvarchar(4000)',@p__linq__0='283CCB41-3BDF-4BEF-BD26-E46191CA069D',@p__linq__1=N'FIN.SATISFATURA.E'

我认为问题出在EF并证明我运行这样的代码

        var yetkiler1 = Context.Set<KullaniciYetkiView>().Where(y => y.KullaniciId == kullaniciId && y.YetkiKod == yetkiKod).Distinct().ToList();
        var yetkiler2 = Context.Set<KullaniciYetkiView>().Where(y => y.KullaniciId == kullaniciId && y.YetkiKod == yetkiKod).ToList().Distinct();

第一个查询返回115行，第二个返回1.

我错过了什么？

提前致谢。

像昆顿一样说我的模型配置错了。

如果您有超过1列作为键，则应在上下文中设置它们 OnModelCreating 方法，例如modelBuilder.Entity<KullaniciYetkiView>().HasKey(ky => new { ky.KullaniciId, ky.LokasyonId, ky.YetkiId });

这是HasKey方法的解释。 http://msdn.microsoft.com/en-us/library/gg671266(v=vs.103).aspx
