實體框架核心 postgresql 數組類型映射不起作用

Question

我有一個奇怪的問題，也許這是我遺漏的問題，但我有以下 LINQ Lambda 查詢：

var ss = ctx.ShipZones.SelectMany(
                z => ctx.ShipDecks,
                (z, d) =>
                    new
                    {
                        Zone = z.ZIndex,
                        Deck = d.DIndex,
                        Value = ctx.Tags
                            .AsExpandable()
                            .Include(s => s.TagSettings.Device.System)
                            .Where(s =>
                                 s.TagSettings.TagTypeId == 171
                                 && s.TagSettings.Device.System.Id == z.Id
                                 && s.TagSettings.Device.ControlArea.Contains(d.Id)

                                    )
                            .Average(s => s.Value)

                    }
                ).ToList();

根據這篇文章，這應該翻譯成這樣：

SELECT z.z_index AS "Zone", d.d_index AS "Deck", (
  SELECT AVG(t.value)
  FROM tags_current_data AS t
  INNER JOIN tags_settings AS t0 ON t.tag_id = t0.id
  INNER JOIN systems_devices AS s ON t0.device_id = s.id
  INNER JOIN systems AS s0 ON s.system_id = s0.id
  WHERE ((t0.tag_type_id = 171) AND (s0.id = z.id)) AND (d.id = ANY(s.control_area))) AS "Value"
FROM zones AS z
CROSS JOIN decks AS d

但不知何故，翻譯后的查詢是這樣的：

SELECT z.z_index AS "Zone", d.d_index AS "Deck", (
  SELECT AVG(t.value)
  FROM tags_current_data AS t
  INNER JOIN tags_settings AS t0 ON t.tag_id = t0.id
  INNER JOIN systems_devices AS s ON t0.device_id = s.id
  INNER JOIN systems AS s0 ON s.system_id = s0.id
  WHERE ((t0.tag_type_id = 171) AND (s0.id = z.id)) AND (TRUE = FALSE)) AS "Value"
FROM zones AS z
CROSS JOIN decks AS d

不同之處在於它應該在d.id = ANY(s.control_area)它是TRUE = FALSE

誰能告訴我我做錯了什么？

我能夠解決我的問題。 這是在這個問題。

基本上：

它在實體配置中。 Device實體中的ControlArea屬性是List<long>類型。 當我將其更改為long[] （長數組）時，它起作用了！
