如何从LinQ2Entity查询返回List

Question

我希望从以下LinQ查询返回一个列表，但我不知道如何。这是查询。该方法的返回类型应该是什么以及如何返回？

 public IQueryable<object> getDNISData(int DNIS)
    {
        using (VPEntities VPCtx = new VPEntities())
        {
            var DD = 
                from nm in VPCtx.NumberMaps
                join g in VPCtx.Greetings on nm.Greeting_ID equals g.Greeting_ID
                join p1 in VPCtx.Prompts on nm.Prompt1_ID equals p1.Prompt_ID
                join p2 in VPCtx.Prompts on nm.Prompt2_ID equals p2.Prompt_ID
                join p3 in VPCtx.Prompts on nm.Prompt3_ID equals p3.Prompt_ID
                join p4 in VPCtx.Prompts on nm.Prompt4_ID equals p4.Prompt_ID
                join p5 in VPCtx.Prompts on nm.Prompt5_ID equals p5.Prompt_ID
                join h1 in VPCtx.HoldMsgs on nm.HoldMsg1_ID equals h1.HoldMsg_ID
