C#MVC返回视图(对象)会产生查询字符串吗？

Question

我有这个actionresult方法:

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

这是我的观点:

<%@ 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>

我在页面上看到的内容是正确的(测试创建成功).但我的查询符如下所示:

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

编辑:从这个方法调用ActionResult:

public ActionResult CreateMenuItem(FormCollection fc)
{
    MenuItem menuItem = CreateMenuItemFrom(fc);
    SaveMenuItem(menuItem);

    return RedirectToAction("MenuItemCreated", menuItem);
}

编辑二:

对应观点:

<% 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>

<% } %>

为什么是这样？我不希望显示查询字符串.

问题是以下几行:

return RedirectToAction("MenuItemCreated", menuItem);

执行重定向时,无法传递此类复杂对象.只有简单的标量属性:

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

然后在动作内部重定向以获取给定id的相应菜单项模型:

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