即使我相信我已经定义了所有模型并希望正确传递，但我收到一个错误，指出当需要另一个模型时我正在传递一个模型。

主视图：

@model Project.Models.ProfileModel

 @(ViewBag.HasLocalPassword ? Html.Partial("_ChangePasswordPartial", Model.PasswordModel) : Html.Partial("_SetPasswordPartial", Model.PasswordModel))

            @Html.Partial("_UsernamePartial", Model.UsernameModel)
            @Html.Partial("_PlayNamePartial", Model.PlayNameModel)

楷模：

 public class ProfileModel
{
    public PasswordModel PasswordModel { get; set; }
    public PlayNameModel PlayNameModel { get; set; }
    public UsernameModel UsernameModel { get; set; }
}

用户名操作 GET：

public ActionResult _UsernamePartial()
    {
        var usernameModel = new UsernameModel();
        using (var db = new DataContext())
        {
            usernameModel.Username =
                (from u in db.Users where u.ID == WebSecurity.CurrentUserId select u.Username).FirstOrDefault();
        }
        return PartialView(usernameModel);
    }

用户名 POST 操作：

[HttpPost]
    public ActionResult _UsernamePartial(UsernameModel usernameModel)
    {
        if (ModelState.IsValid)
        {
            using (var db = new DataContext())
            {
                User user = db.Users.FirstOrDefault(u => u.ID == WebSecurity.CurrentUserId);
                user.Username = usernameModel.Username;
                db.SaveChanges();
            }
        }
        return View("_UsernamePartial");
    }

配置文件操作：

public ActionResult Profile(ManageMessageId? message)
    {
        var profile = New ProfileModel();
        ViewBag.StatusMessage =
            message == ManageMessageId.ChangePasswordSuccess ? "Your password has been changed."
            : message == ManageMessageId.SetPasswordSuccess ? "Your password has been set."
            : message == ManageMessageId.RemoveLoginSuccess ? "The external login was removed."
            : "";
        ViewBag.HasLocalPassword = OAuthWebSecurity.HasLocalAccount(WebSecurity.GetUserId(User.Identity.Name));
        ViewBag.ReturnUrl = Url.Action("Profile");
        return View(profile);


    }

用户名的查看页面：

@model Acatar.Models.UsernameModel

@using (Html.BeginForm("_UsernamePartial", "Account")) {

       <p id="legend">Username</p>
       @Html.TextBoxFor(m=>m.Username)

    <button type="submit" value=" Username">Save</button>
}

错误信息： The model item passed into the dictionary is of type 'Project.Models.ProfileModel', but this dictionary requires a model item of type 'Project.Models.UsernameModel'.

非常感谢我哪里出错的任何帮助。

当您发布到 时_UsernamePartial，这充当返回另一个 Partial 的子操作方法。你正在回过头来

您实际上是在传回 View _UsernamePartial 但返回它

return View("_UsernamePartial");

没有 usernameModel

如果您调用 Html.Partial 我不相信它会调用操作方法。您应该使用 Html.RenderAction() 来调用控制器操作。
