MVC:显示分组列表的视图

Question

我在Asp.net框架上使用MVC5，我想创建一个将信息分组的视图，如下所示：

Animal Species: Lion
      Individual: Mufusa, age 6
      Individual: Simba, age 2
Animal Species: Wolf
      Individual: Lupa, age 5
      Individual: Charlie, age 3

现在，我在View文件中使用了"@foreach (var item in Model)“语句，输出如下：

Animal Species: Lion
     Individual: Mufusa, age 6
Animal Species: Lion
     Individual: Simba, age 2
Animal Species: Wolf
     Individual: Lupa, age 5
Animal Species: Wolf
     Individual: Charlie, age 3

对如何做到这一点有什么建议吗？提前感谢您的帮助。

Answer 1

     var queryGroupBySpecies = from animal in animals
                                   group new { animal .FirstName, animal.age}  75 into animalGroup 
select animalGroup ;

然后，您将迭代foreach两次

   foreach (var animalGroup in queryGroupBySpecies )
    { 
        foreach (var animal in animalGroup )
            Console.WriteLine($"\t{animal.FirstName} {animal.age}");
    }
