如何在foreach linq两级查询中读取

我在查询和创建两级关系时遇到的问题如下：

拉姆达：

public IList GetMasterDetailsFilterLang(string language)
        {
            var query = (_ourServiceCategories
                           .Where(c => (c.Language == "fa-IR"))
                           .Select(
                              c =>
                                 new
                                 {
                                     CatId = c.Id,
                                     CatName = c.Title,
                                     OurServices = c.OurServices
                                        .Select(
                                           o =>
                                              new
                                              {
                                                  ServId = o.Id,
                                                  ServName = o.Title
                                              }
                                        )
                                 }
                           )).ToList();

            return query;
        }

林克：

    from c in OurServiceCategories
where c.Language == "fa-IR"
select new
{
CatId = c.Id,
CatName = c.Title,
OurServices = from o in c.CategoryOurServices
select new 
 { 
  ServId = o.Id,
  ServName = o.Title
 }
}

结果：

现在：我不知道如何使用这个，Foreach如何阅读

我想这样读：

var ds = OurServiceService.GetMasterDetailsFilterLang(_LangSar);

foreach (var d in ds)
        {

            //Read Master example : d.Id,d.Title
            //do something
            foreach (var details in d)
            {
                //Read Details example : details.Id,details.Name
                //do something
            }

        }

对于d.OurService中的每个var细节您的意思是这样的吗

var ds = from c in OurServiceCategories
            where c.Language == "fa-IR"
            select new
            {
            CatId = c.Id,
            CatName = c.Title,
            OurServices = from o in c.CategoryOurServices
            select new 
             { 
              ServId = o.Id,
              ServName = o.Title
             }
            };
foreach (var d in ds)
{
    //here you can access d.CatId & d.CatName
    foreach (var details in d.OurServices)
    {
        //here you can access details.ServId & details.ServName
    }
}

问题是什么？您是否希望获得与屏幕截图相同的结果，但使用2级foreach而不是LINQ，就像您已经做的那样？请使用完整代码编辑文章

var ds = from c in OurServiceCategories
            where c.Language == "fa-IR"
            select new
            {
            CatId = c.Id,
            CatName = c.Title,
            OurServices = from o in c.CategoryOurServices
            select new 
             { 
              ServId = o.Id,
              ServName = o.Title
             }
            };
foreach (var d in ds)
{
    //here you can access d.CatId & d.CatName
    foreach (var details in d.OurServices)
    {
        //here you can access details.ServId & details.ServName
    }
}
