查询结果过滤有问题。

public class LinkTabProductCategory
{
    [Key]
    public int Id { get; set; }

    public int ProductId { get; set; }
    [JsonIgnore]
    public Product Product { get; set; }

    public int CatalogSubSectionId { get; set; }
    public CatalogSubSection CatalogSubSection { get; set; }
}

var result = DataContext.Product                    
                .Include(o => o.Offers)
                        .ThenInclude(p => p.Prices)
                            .ThenInclude(t => t.Type)
                .Include(p => p.Brand)
                .Include(tb=>tb.LinkTabProductCategories)
                .Where( p=>p.LinkTabProductCategories **???** == id)
                .ToList();

我需要获得产品列表，其中有：链接选项卡产品类别.目录子章节Id == id

***更新***这是查询结果列表：

{
    "ProductId":"",
    "UID1C": "",
    "Name": "",
    "Article": "",
    "FactoryNumber": "",
    "Brand": {
        "BrandId": "",
        "UID1C": "",
        "Name": ""
    },
    "Offers": []       
    ,
    "LinkTabProductCategories": [
        {
            "Id": 1,
            "ProductId": 2,
            "CatalogSubSectionId": 1,
            "CatalogSubSection": null
        }
    ]
},
{},
{}.....

如何仅获取“CatalogSubSectionId”== 1的产品
