asp.net-mvc - 创建 View 正在发布空对象

Question

应该是一个容易回答的问题。
我正在尝试在 View 中创建一个对象。包含对象的类由一个 User 类和一个密码组成。
当我点击提交按钮时， Controller 为密码和用户选择空值。
见下面的容器类、 Controller 和 View ；

public class UserExtended
{
    public UserITOC User { get; set; }
    public string Password { get; set; }
}

    [Authorize]
    public ActionResult Create()
    {
        return View(new UserExtended());
    }

    //
    // POST: /Dinners/Create

    [Authorize(Roles = "Administrator")]
    [HttpPost]
    public ActionResult Create(UserExtended user)
    {
        if (ModelState.IsValid)
        {
            // Create user in the User datatable
            SqlUsersRepository sqlRepository = new SqlUsersRepository();
            ITOCEntities db = new ITOCEntities();
            db.UserITOCs.AddObject(user.User);

            // Create user as an authenticated user within the Reader role.
            int i = user.User.EmailAddress.IndexOf('@') - 1;
            string userName = user.User.EmailAddress.Substring(0, i);
            string email = user.User.EmailAddress;
            Membership.CreateUser(userName, user.Password, email);
            Roles.AddUserToRole(userName, "Reader");                // Automatically assigned as a Reader
        }
        return View(new UserExtended());
    }

        </div>
        <div class="editor-field">
            <%: Html.EditorFor(model => model.User.EmailAddress)%>
            <%: Html.ValidationMessageFor(model => model.User.EmailAddress)%>
        </div>

        <div class="editor-label">

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>

<% } %>

<div>
    <%: Html.ActionLink("Back to List", "Index") %>
</div>

Answer 1

极其简单的解决方案:

更改您的操作签名

public ActionResult Create(UserExtended user)

至

public ActionResult Create(UserExtended UserExtended)

这样，ModelBinder将知道如何从Request中重新组装对象。

希望这可以帮助!
