Question

我试图在EF Core中应用加入，但它返回了错误的数据。

如果我在SQL Server中运行以下查询，则返回无结果，即预期的行为。

select * from device d
inner join  store s on s.Id = d.StoreId
inner join category c on c.Id = d.CategoryId
where s.StoreName like '%dsfd%' and c.CategoryName like '%asdasdasd1%'

但是当我尝试从C＃应用程序运行相同的输入值的类似代码时，它返回一行。

var serachresult = (from devices in _deviceRepository.GetAll()
join stores in _storeRepository.GetAll() on devices.StoreId equals stores.Id
join categories in _categoryRepository.GetAll() on devices.CategoryId equals categories.Id 
where

(!string.IsNullOrWhiteSpace(searchInput.StoreName) ? stores.StoreName.Contains(searchInput.StoreName) : true) &&

(!string.IsNullOrWhiteSpace(searchInput.CategoryName) ? categories.CategoryName.Contains(searchInput.CategoryName) : true) 

select new DeviceDetailsDto

{
    Id = devices.Id,
    DeviceName = devices.DeviceName,
    DeviceDesc = devices.DeviceDesc,
    DeviceCode = devices.DeviceCode,
    StoreId = devices.StoreId,
    CategoryId = devices.CategoryId,
    CategoryName = categories.CategoryName,
    StoreName = stores.StoreName
});
