Question

如果你将匿名物体退回控制员,则通过查阅匿名物体财产名称来掩饰控制者的论点,那么,我如何将相关物体的特性退回到我的模型中,以便违约价值对控制者具有约束力?

For example:

Model:

public class MyViewModel
{
    public MyItem MyItem { get; set; }
}

public class MyItem
{
    public string Name { get; set; }
}

Controller:

public ActionResult Index(MyViewModel model)
{
    return View(model);
}

In the view, I want to pass the MyItem.Name back, how is this possible? I have tried:

@Html.ActionLinke("Index", "MyController", new { name = "example" })

and

@Html.ActionLinke("Index", "MyController", new { myItem_Name = "example" })

Help please!

Answer 1

答案是创建一种惯例模型Binder和模型BinderProvider。

Answer 2

您:

@Html.ActionLink("Index", "MyController", new { name = @Model.MyItem.Name })

在行动方法中:

public ActionResult Index(string name)
{
    return View();
}

Answer 3

您可使用以下超载:

@Html.ActionLink( 
    "link text",                             // linkText
    "Index",                                 // actionName
    "MyController",                          // controllerName
    new RouteValueDictionary {               // routeData
        { "MyItem.Name", "example" } 
    }, 
    null                                     // htmlAttributes
)

Answer 4

I think you may be misunderstanding the passing of object from view to controller . It s not that you re passing object - you re just rendering a link (anchor tag) in the page. The request will actually come from the browser when the user clicks the link. There is no server-side object passing going on.

链接必须包含服务器(控制器)作为查询参数所需要的所有参数。

我认为,你真的想要做的是:

render a form and submit it, or
仅通过你所需要的数据,在控制器检索数据(例如从非行取)
