当试图将模型绑定到视图时，出现404错误。 ActionResult被称为“SortDesc”，但视图只是一个标准的“索引”视图。我明白，这是不加载，因为现在有称为'SortDesc'的视图。然而，我有两个按钮一个排序数据升序和一个排序数据降序因此两个独立的功能。我只是不确定什么是最好的解决方案会在这里，要么继续两个分开的函数，并以某种方式传递正确的视图加载或在索引上创建一个新的，单个HttpPost函数，将知道哪个按钮已被点击并相应地排序。下面的代码我到目前为止：绑定模型以查看
型号：
public class NumberSetList
{
public int NumberSetListId { get; set; }
public List<NumberList> Numbers { get; set; }
public string SortOrder { get; set; }
}
public class NumberList
{
public int NumberListId { get; set; }
public int Number1 { get; set; }
public int Number2 { get; set; }
public int Number3 { get; set; }
public int Number4 { get; set; }
public int Number5 { get; set; }
public string SortOrder { get; set; }
}

首页控制器：
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult SortDesc([Bind(Include = "Number1, Number2, Number3, Number4")] NumberSetList model)
{
if (!ModelState.IsValid)
{
return View();
}
else
{
NumberSetList list = new NumberSetList();
List<int> numbers = new List<int>();
numbers.Add(model.Number1);
numbers.Add(model.Number2);
numbers.Add(model.Number3);
numbers.Add(model.Number4);
numbers.OrderByDescending(i => i);
list.SortOrder = "Desc";
return View(list);
}
}
在操作中，变量'numbers'没有分配到任何创建的投入。这个观点将如何被意识到呢？您需要设置'list.numbers =数字;' – Nkosi
