Passing data to view is simple as passing object to method. Take a look at Controller.View Method
将数据传递给视图就像将对象传递给方法一样简单。看一下 Controller.View 方法
protected internal ViewResult View(
Object model
)
Something like this
像这样的东西
//controller
List<MyObject> list = new List<MyObject>();
return View(list);
//view
@model List<MyObject>
// and property Model is type of List<MyObject>
@foreach(var item in Model)
{
<span>@item.Name</span>
}

I did this;
我这样做了；
In controller:
在控制器中：
public ActionResult Index()
{
var invoices = db.Invoices;
var categories = db.Categories.ToList();
ViewData["MyData"] = categories; // Send this list to the view
return View(invoices.ToList());
}
In view:
鉴于：
@model IEnumerable<abc.Models.Invoice>
@{
ViewBag.Title = "Invoices";
}
@{
var categories = (List<Category>) ViewData["MyData"]; // Cast the list
}
@foreach (var c in @categories) // Print the list
{
@Html.Label(c.Name);
}
<table>
...
@foreach (var item in Model)
{
...
}
</table>
Hope it helps
希望能帮助到你

You can use the dynamic object ViewBagto pass data from Controllers to Views.
您可以使用动态对象ViewBag将数据从控制器传递到视图。
Add the following to your controller:
将以下内容添加到您的控制器中：
ViewBag.MyList = myList;
Then you can acces it from your view:
然后您可以从您的角度访问它：
@ViewBag.MyList
// e.g.
@foreach (var item in ViewBag.MyList) { ... }

Create a model which contains your list and other things you need for the view.
For example:
public class MyModel { public List<string> _MyList { get; set; } }From the action method put your desired list to the Model,
_MyListproperty, like:public ActionResult ArticleList(MyModel model) { model._MyList = new List<string>{"item1","item2","item3"}; return PartialView(@"~/Views/Home/MyView.cshtml", model); }In your view access the model as follows
@model MyModel foreach (var item in Model) { <div>@item</div> }
创建一个模型，其中包含您的列表和视图所需的其他内容。
例如：
public class MyModel { public List<string> _MyList { get; set; } }从 action 方法将您想要的列表放到 Model
_MyList属性中，例如：public ActionResult ArticleList(MyModel model) { model._MyList = new List<string>{"item1","item2","item3"}; return PartialView(@"~/Views/Home/MyView.cshtml", model); }在您的视图中访问模型如下
@model MyModel foreach (var item in Model) { <div>@item</div> }
I think it will help for start.
我认为这将有助于开始。
