我無法從表 ASP.NET Core MVC 中檢索我的數據

Question

之前試過，正常，不知道為什么會這樣。 我無法從表中檢索我的數據。 只有這張表無法獲取數據。 另一方面，一切正常

錯誤信息

SqlNullValueException：數據為 Null。 不能對 Null 值調用此方法或屬性。

Controller代碼

public IActionResult IndexWGI()
    {
        IEnumerable<VerDummyWellGeneralInformation> wgi = _db.VerDummyWellGeneralInformations;
        return View(wgi);
    }

我所有其他人的索引都一樣，但在這個上不會得到任何數據

抱歉，我意識到我的 model 數據類型已被查找和替換更改。

public int Northing { get; set; }

那是改名的代碼
