我試圖讓EF6流利映射爲我當前的項目工作。我有以下訂單映射：EF6 Fluent映射不正確的連接鍵
public class OrderMap : EntityTypeConfiguration<Order>
{
public OrderMap()
{
this.ToTable("OE_Orders");
this.Property(o => o.BillToAddress.Address1).HasColumnName("BillToAddress1");
this.Property(o => o.BillToAddress.Address2).HasColumnName("BillToAddress2");
this.Property(o => o.BillToAddress.City).HasColumnName("BillToCity");
this.Property(o => o.BillToAddress.State).HasColumnName("BillToState");
this.Property(o => o.BillToAddress.Zip).HasColumnName("BillToZip");
this.Property(o => o.ShipToAddress.Address1).HasColumnName("ShipToAddress1");
this.Property(o => o.ShipToAddress.Address2).HasColumnName("ShipToAddress2");
this.Property(o => o.ShipToAddress.City).HasColumnName("ShipToCity");
this.Property(o => o.ShipToAddress.State).HasColumnName("ShipToState");
this.Property(o => o.ShipToAddress.Zip).HasColumnName("ShipToZip");
this.Property(o => o.Stop).HasColumnName("RouteStopNumber");
this.HasKey(o => o.OrderNumber).HasMany(o => o.OrderLines).WithRequired(ol => ol.Order).HasForeignKey(ol => ol.OrderNumber);
this.HasKey(o => o.CustomerKey).HasRequired(o => o.Customer).WithRequiredDependent();
}
}
由於某種原因，這會嘗試將CustomerKey映射到OrderLines而不是OrderNumber。我不知道爲什麼。如果您需要它，我還可以包含OrderLineMap。生成的SQL是：

WHERE [Extent1].[OrderNumber] = @p__linq__0
) AS [Project1]
ORDER BY [Project1].[CustomerKey] ASC, [Project1].[CustomerKey1] ASC, [Project1].[C1] ASC
這是有問題的行：
LEFT OUTER JOIN [dbo].[OE_OrderLines] AS [Extent3] ON [Extent1].[CustomerKey] = [Extent3].[OrderNumber]
不知道如何解決它。我可以使用一些建議或一些資源來幫助我弄清楚它爲什麼映射不正確。
讓我知道如何更新此信息以使其更具信息性。
謝謝大家的時間！
是'Order' - >'Customer'關係真的'一對-one'？很奇怪，通常一個'客戶'有很多'訂單'，不是嗎？ –
@IvanStoev是的，客戶有很多訂單，但我沒有將客戶與訂單集合進行映射。這太多了。我可以添加它，但這不是必需的。 – Carson
它不一定有一個集合。但'擁有'/'擁有'必須與關係基數相符。讓我以不同的方式問你 - 「Order.CustomerKey」是FK到「Customer」表嗎？ –
