c# - 将多个参数从 url 传递到 html.actionlink

Question

我是 MVC 的新手，当我尝试通过 URL 传递多个参数时，我遇到了路由问题。

来自具有 URL 的页面:/PersonCAFDetail/Index/3?memberid=4

...我正在尝试将 Html.ActionLink 设置为指向创建操作，以便 id=3 和 memberid=4。

阅读了许多类似的帖子后，似乎以下内容应该有效:

@Html.ActionLink("Create New", "Create", null, new { memberid = "memberid" })

但是，这会导致创建如下 URL:

<a href="/PersonCAFDetail/Create/3" memberid="memberid">Create New</a>

我有一条路线设置为:

    routes.MapRoute(
        name: "PersonCAFDetail",
        url: "PersonCAFDetail/Create/{id}/{memberid}",
        defaults: new { controller = "PersonCAFDetail", action = "Create", id = "@\d+", memberid = @"\d+" }                        
        );

Controller 接受如下两个参数:

 public ActionResult Create(int id, int memberid)
        {
            int cafID = id;
            int personID = memberid;
            ViewBag.detailTypeID = new SelectList(db.tCAFDetailTypes, "detailTypeID", "detailType");
            ViewBag.cafID = new SelectList(db.tFamilyCAFs, "cafID", "issues");
            ViewBag.personID = new SelectList(db.tPersons, "personID", "forename");
            return View();
        }

感谢任何帮助。

        public virtual tFamilyCAF tFamilyCAF { get; set; }

    }
}

最后，您需要向 View 传递两个参数:

索引操作:

public ActionResult Index(int id, int memberid)
{
    ...
    ViewBag.cafID = id;
    ViewBag.personID = memberid;
    return View();
}

索引.cshtml

@Html.ActionLink("Create New", "Create", "PersonCAFDetail", new { id=ViewBag.cafID , memberid =ViewBag.personID}, null)

并检查你的路由语法... id = @"\d+"

 routes.MapRoute(
    name: "PersonCAFDetail",
    url: "PersonCAFDetail/Create/{id}/{memberid}",
    defaults: new { controller = "PersonCAFDetail", action = "Create", id = @"\d+", memberid = @"\d+" }                        
    );
