C#MVC返回查看(对象)的结果是查询字符串? [英] C# MVC Return view(object) results in a querystring?
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:
http://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);
...
}
