大家好，小弟一个linq的问题请教一下大家
如下图

通过linq我怎么查出_newsource为新浪科技的条目呢？
这些item都在SampleDataSource.AllNewsGroups这个数据集合里
麻烦大家了~~
------解决方案--------------------
 DataTable dt = new DataTable();

            var a = from t in dt.AsEnumerable()
                    where t.Field<string>("isindoor") == "新浪科技"
                    orderby t.Field<decimal>("utility_rate")
                    select t;

------解决方案--------------------

            List<AllNewsGroups> AllNewsGroups = new List<AllNewsGroups>();

            List<AllNewsGroups2> AllNewsGroups2 = new List<ceshi.AllNewsGroups2>();

            AllNewsGroups2.Add(new AllNewsGroups2 { Name = "新浪科技" });

            AllNewsGroups2.Add(new AllNewsGroups2 { Name = "新浪科技" });

            AllNewsGroups2.Add(new AllNewsGroups2 { Name = "新浪科技" });

            AllNewsGroups2.Add(new AllNewsGroups2 { Name = "新浪科技" });





            AllNewsGroups.Add(new AllNewsGroups { Name = "1",AllNewsGroups2 = AllNewsGroups2 });





            AllNewsGroups.Select(m => (m.AllNewsGroups2.Where(t => t.Name == "新浪科技")).Count()>0);





 public class AllNewsGroups

    {

        public string Name{get;set;}

        public List<AllNewsGroups2> AllNewsGroups2 { get; set; }

    }



    public class AllNewsGroups2

    {

        public string Name { get; set; }

    }

------解决方案--------------------
var query=SampleDataSource.AllNewsGroups.Items.Where(x=>x._newsource=="新浪科技");
------解决方案--------------------
SampleDataSource.AllNewsGroups.SelectMany(x => x.Where(y => y._newsource == "新浪科技")));
