Question

首先发布在这里，所以如果这篇文章不是很好，我很抱歉！我目前正在使用asp.net构建一个Web应用程序，并遇到了这个问题：

传递到字典中的模型项的类型为“Daily_Planner.Models.DayPlanPartialview”，但此字典需要“Daily_Planner.Models.Group”类型的模型项

似乎我在传递正确的模型时遇到了问题。我正在使用几个部分视图，我担心我可能会使用我的模型错误，但我无法找出它是什么。我尝试过提供足够的信息，但是如果你需要更多信息，我会更愿意发布更多的代码。

部分视图_GroupManage：

@model IEnumerable<Daily_Planner.Models.Group>
<select>
    @foreach (var item in Model)
    {
        <option value="@item.Id">@item.GroupName</option>

    }
</select>

部分视图_layout：

@if (Request.IsAuthenticated)
{
    @Html.ActionLink("Daily Planner", "Index", "Home", new { area = "" }, new { @class = "navbar-brand" })
}
else
{
    @Html.ActionLink("Daily Planner", "Login", "Account", new { area = "" }, new { @class = "navbar-brand" })
}
@if (Request.IsAuthenticated)
{
    { Html.RenderPartial("_GroupManage"); }
    @Html.Partial("_LoginPartial")
}

型号：

namespace Daily_Planner.Models
{
    public class DayPlanPartialview 
    { 
     public DayPlan displayComments { get; set; }
     public Group groupM { get; set; }
     public IEnumerable<Daily_Planner.Models.DayPlan> ListofComments { get; set;}
     public IEnumerable<Daily_Planner.Models.Group> groupmanage{ get; set; }
    }

的HomeController

namespace Daily_Planner.Controllers
    {
        public class HomeController : Controller
        {
            private ApplicationDbContext db = new ApplicationDbContext();
            private DayPlanPartialview pv = new DayPlanPartialview();


            [Authorize]
            public ActionResult Index()
            {
                // Add list of comments with newest comment first // .Take(10).ToList(); will only show the last 10 posts
                pv.ListofComments = db.DayPlans.OrderByDescending(x => x.DateCreated).ToList();
                return View(pv);
            }

            [HttpPost]
            [Authorize]
            public ActionResult Index(DayPlanPartialview dayP)
            {
                dayP.displayComments.ApplicationUserId = User.Identity.GetUserId();
                dayP.displayComments.DateCreated = DateTime.Now;
                db.DayPlans.Add(dayP.displayComments);
                db.SaveChanges();
                pv.ListofComments = db.DayPlans.ToList();

                return RedirectToAction("");
            } 

     @model IEnumerable<Daily_Planner.Models.Group>
        <select>
            @foreach (var item in Model)
            {
                <option value="@item.Id">@item.GroupName</option>

            }
        </select>

将错误的模型传递给字典
