asp.net - 在 asp.net mvc 中传入字典的模型项

问题描述

执行程序时出现错误，错误内容为：传入字典的模型项的类型为“System.Data.Entity.DynamicProxies.Child_A03B4AB53F9E2ED1CB70F81E60FFA68CF868CF01DE6D2C340D267350F8543009”，但该字典需要“adminSection.Models.Note”类型的模型项。

执行此视图时

   @model adminSection.Models.Note
@{
    ViewBag.Title = "Add_Note";
}

<h2>Add_Note</h2>
@using (Html.BeginForm("Add_Note", "Admin", FormMethod.Post))
{
    <div class="form-horizontal">
        <div class="form-group">
            @Html.LabelFor(x=>x.Note_title,htmlAttributes:new { @class="label-control col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(x => x.Note_title, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(x => x.Note_title, null, new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(x => x.Note_title, htmlAttributes: new { @class = "label-control col-md-2" })
            <div class="col-md-10">
                @Html.TextAreaFor(x => x.Note_title, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(x => x.Note_title, null, new { @class = "text-danger" })
            </div>
        </div>

    </div>
    <div>
        <input type="submit" value="Add" class="btn btn-default" />
    </div>


}

我的控制器是

[HttpGet]
    public ActionResult Add_Note(int? id)
    {
        if (Session["ID"] == null)
            return RedirectToAction("Login", "Home");
        else
        {
            if (id == null)
            {
                return HttpNotFound();
            }
            else
            {
                using (Context db = new Context())
                {
                    var child = db.child.Find(id);
                    if (child == null)
                    {
                        return HttpNotFound();
                    }
                    else
                    {
                        return View(child);
                    }

                }


        }
    }
}
[HttpPost]
public ActionResult Add_Note(Note note, Child child)
{
    if (ModelState.IsValid)
    {
        note.Child_id = child.Chi_Id;
        note.Note_Date = DateTime.Now;
        child.note = new List<Note>();

        db.Entry(child).State = EntityState.Modified;
        var admin = db.admin.Find(Session["Id"]);
        if (admin != null)
        {
            if (admin.Adm_Name == Session["Name"].ToString())
            {
                admin.note = new List<Note>();
                admin.note.Add(note);
                db.Entry(admin).State = EntityState.Modified;
                note.admin = admin;
                //db.SaveChanges();
            }
        }
        else
        {
            return HttpNotFound();
        }
    }

    child.note.Add(note);
    note.child = child;
    db.note.Add(note);
    db.SaveChanges();
    return RedirectToAction("Home", "Admin");
}

解决方案

我认为使用对象的类型（可能是 Note）而不是varinvar child = db.child.Find(id)可以解决您的问题。
