一个组内有4组数据，现在要调用4个合起来的数据怎么调用

public async Task Index()
{
var list = await db.Tips.ToListAsync();
list.Reverse();
Tuple,List, List, List> t = new Tuple, List, List, List>(list.Where(v => v.AuthorName == "Project Z").Take(15).ToList(), list.Where(v => v.AuthorName == "S - POOP").Take(15).ToList(), list.Where(v => v.AuthorName == "VIETECH").Take(15).ToList(), list.Where(v => v.AuthorName == "玩物").Take(15).ToList());
return View(t);
}

            用@foreach (var video in Model.Item3) { 可以调用第三组
            有一栏需要调用全部的数据~但是tuple只能包含4组数据这个怎么调用

用foreach遍历不就可以了吗
