如何禁用实体框架创建Nullable属性的

有没有办法禁用或停止实体框架在复杂类中创建Nullable属性？

例如，当我向实体框架添加一个新的存储过程时，它将生成一个类似于以下类的类。

    //------------------------------------------------------------------------------

namespace StorefrontSystemDL
{
    using System;

    public partial class proc_InsertLeafHorizontal_Result
    {
        public Nullable<int> SizeID { get; set; }
        public Nullable<int> FinishID { get; set; }
        public Nullable<int> SitelineID { get; set; }
    }
}

我如何，应该执行或没有可以设置为实体框架不使用Nullable类型创建属性的设置

以下是源列的快照。

对于我的存储过程，这里是tsql的主体

    AS
BEGIN
SET NOCOUNT ON;

 BEGIN TRAN
   BEGIN TRY
EXEC Storefront.proc_InsertHorizontal @Position,@Name,@Floor,@IsFiller,
                                      @WidthInches,@HeightInches,@WidthPercent,@HeightPercent,
                                      @DayliteWidthInches,@DayliteHeightInches,
                                      @Finish,@FinishNote,@FinishType,@FinishName,
                                      @ComponentID,@Note,
                                      @HorizontalID OUT;
    IF(@HorizontalID IS NOT NULL)
     INSERT INTO [StorefrontSystem].[Storefront].[LeafHorizontal]
           ([LeafID]
           ,[HorizontalID])
     VALUES
           (@LeafID,
            @HorizontalID)
----
SELECT h.SizeID,h.FinishID,h.SitelineID FROM Storefront.Horizontal h WHERE h.ID = @HorizontalID;
COMMIT TRAN
END TRY
 BEGIN CATCH
   ROLLBACK TRAN;
 END CATCH
SET NOCOUNT OFF;
END;
