ASP.NET MVC：路由帮助 [英] ASP.NET MVC: routing help

问题描述

考虑控制器 CustomerController.cs 的两种方法：

Consider two methods on the controller CustomerController.cs:

//URL to be http://mysite/Customer/
public ActionResult Index()
{
    return View("ListCustomers");
}

//URL to be http://mysite/Customer/8
public ActionResult View(int id)
{
    return View("ViewCustomer");
}

• 你将如何设置你的路线，以适应这一要求？


• 您将如何创建一个链接视图页？
在当前使用Html.ActionLink

• How would you setup your routes to accommodate this requirement?
• How would you use Html.ActionLink when creating a link to the View page?

推荐答案

在的global.asax.cs，添加如下（假设你使用默认的MVC的Visual Studio模板）

In global.asax.cs, add following (suppose you use the default mvc visual studio template)

Route.MapRoute("Customer",
    "Customer/{id}",
    new { Controller = "CustomerController", action="View", id="" });

请确保你把该路由的默认路由之前在模板

Make sure you put this route before the default route in the template

您则需要修改控制器。对于视图，

You then need to modify your controller. For the view,

public ActionResult View(int? id)
{
    if (id == null) 
    {
        return RedirectToAction("Index"); // So that it will list all the customer
    }
    //...The rest follows
}

有关你的第二个问题，ActionLink的很简单。

For your second question, ActionLink is simple.

Html.ActionLink("Link Text", "View", "Customer", new {id=1}, null);
