實體框架查詢結果

Question

我正在使用EntityFramework 4.3.1並嘗試運行這樣的查詢

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

當我運行查詢時，它按預期返回115條記錄。 但是當我查看記錄時，所有記錄都是相同的。 因此，我偵聽了探查器的查詢，以查找我缺少的內容，請參閱以下查詢，並從Management Studio返回115條不同的記錄。

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'

我認為問題出在EF，為了證明這一點，我運行了這樣的代碼

        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();

第一個查詢返回115行，第二個查詢返回1。

我想念什么？

提前致謝。

就像Quinton所說的那樣，我的模型配置是錯誤的。

如果您有1列以上的鍵，則應在諸如modelBuilder.Entity<KullaniciYetkiView>().HasKey(ky => new { ky.KullaniciId, ky.LokasyonId, ky.YetkiId });等上下文的OnModelCreating方法上進行設置modelBuilder.Entity<KullaniciYetkiView>().HasKey(ky => new { ky.KullaniciId, ky.LokasyonId, ky.YetkiId });

這是HasKey方法的說明。 http://msdn.microsoft.com/zh-CN/library/gg671266(v=vs.103).aspx
