Question

我有一个表格,把照片上载到我的数据库,我利用一种观点模式协助这一进程。

观点模式:

public class GalleryViewModel
{
    //Members:
    public Gallery _photo                { get; set; }
    public string _title                 { get; set; }
    public string _description           { get; set; }
    public string _photographer          { get; set; }
    public HttpPostedFileBase uploadFile { get; set; }


    // Ctor
    public GalleryViewModel(Gallery photo)
    {
        _photo = photo;
    }

    public GalleryViewModel()
    {
        _photo = null;
    }
}

When I debug the code, I see that the in the post method in my controller, all the information from the form is updated in the view model except for the uploadFile which is null. In the form I use enctype = "multipart/form-data". When I use my master page the uploadFile is null but when I use the default MVC master page everything works fine.

<%@ Master Language="C#" MasterPageFile="~/views/Shared/GeneralMaster.master" Inherits="System.Web.Mvc.ViewMasterPage" %>

<asp:Panel ID="notifiactions" runat="server">
   <% if (ViewData["notifications"] != null)
   { %>
        <br />       
            <table width="100%">
                <tr>
                    <td align="center">
                        <div id="messages" style="width: 90%; border: solid 1px #A3A3A3">
                            <br />     
                            <%= Html.Encode(ViewData["notifications"])%>                                
                            <br /><br />
                        </div>
                    </td>
                </tr>
            </table>   
   <% } %>    
</asp:Panel>

<br />
    <table width="100%" cellpadding="0" cellspacing="0">
        <tr>
            <td width="30%" align="center"> 
                <img src="ContentSiteDesignwine_in_frame2.JPG" alt="lk" />
            </td>
            <td width="40%">
                <asp:ContentPlaceHolder ID="PageContent" runat="server" />
            </td>  
            <td width="30%" align="right"> 
                <img src="ContentSiteDesignset_with_frame.jpg" alt="Alon" />
            </td>
        </tr>
    </table>

这里是缺省总页。

<%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %>

    <div id="header">
        <div id="title">
            <h1>My MVC Application</h1>
        </div>

        <div id="logindisplay">
            <% Html.RenderPartial("LogOnUserControl"); %>
        </div> 

        <div id="menucontainer">

            <ul id="menu">              
                <li><%= Html.ActionLink("Home", "Index", "Home")%></li>
                <li><%= Html.ActionLink("About", "About", "Home")%></li>
            </ul>

        </div>
    </div>

    <div id="main">
        <asp:ContentPlaceHolder ID="MainContent" runat="server" />

        <div id="footer">
        </div>
    </div>
</div>

任何想法?

Answer 1

你没有以所张贴的形式发表实际看法,因此我只能猜测:

确实,你把你的形式打上了“多部分/格式数据”的一类,否则,卷宗就用上了。

<form id="form" name="form" action"controller/action" enctype="multipart/form-data">
...
</form>

或与Html求助者:

<% using(Html.BeginForm("action", "controller", "POST", new { enctype = "multipart/form-data" })) {
...
<% } %>

Answer 2

adding this code to form will get multi part data on the form eg: attachement etc.

new { enctype = "multipart/form-data" }

Answer 3

引出主页,是利用我项目主页的继承。

在主页上有一个<代码><form></form> tag encapsulating the <asp:content holder>。消除形式标签将这一问题固定下来。
