C＃MVC返回查看（对象）的结果是查询字符串？

本文介绍了C＃MVC返回查看（对象）的结果是查询字符串？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有这样的ActionResult方法：

I have this actionresult method:

public ActionResult MenuItemCreated(MenuItem item) { return View(item); }

这是我的看法：

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MenuItem>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> MenuItemCreated </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>MenuItemCreated</h2> <%: Model.Caption %> is created succesfully </asp:Content>

我看到网页上是正确的（测试成功创建）。但我的查询字符串看起来像这样：

What I see on the page is correct (test is created successfully). But my querystring looks like this:

localhost:62602/Admin/MenuItemCreated/2?Caption=test&Link=%2Fclient

编辑：该的ActionResult从这个方法叫做：

The ActionResult is called from this method:

public ActionResult CreateMenuItem(FormCollection fc) { MenuItem menuItem = CreateMenuItemFrom(fc); SaveMenuItem(menuItem); return RedirectToAction("MenuItemCreated", menuItem); }

编辑II：

相应的视图：

<% using (Html.BeginForm("CreateMenuItem","Admin",FormMethod.Post)) {%> <%: Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%: Html.LabelFor(model => model.Caption) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Caption) %> <%: Html.ValidationMessageFor(model => model.Caption) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.Link) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Link) %> <%: Html.ValidationMessageFor(model => model.Link) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.ParentId) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.ParentId) %> <%: Html.ValidationMessageFor(model => model.ParentId) %> </div> <p> <input type="submit" value="Create MenuItem" /> </p> </fieldset> <% } %>

这是为什么？我不希望要显示的查询字符串。

Why is this? I don't want the querystring to be shown.

推荐答案

问题是以下行：

return RedirectToAction("MenuItemCreated", menuItem);

当你执行重定向你不可错过这样复杂的对象。只有简单的标量的属性：

You cannot pass complex objects like this when you perform a redirect. Only simple scalar properties:

return RedirectToAction("MenuItemCreated", new { id = menuItem.Id });

然后重定向给出的ID来获取相应的菜单项的模型内的行动：

and then inside the action you are redirecting to fetch the corresponding menu item model given the id:

public ActionResult MenuItemCreated(int id) { var menuItem = _someRepository.GetMenuItem(id); ... }
