传入字典的模型项的类型为 'System.Collections.Generic.List答案

【问题标题】：The model item passed into the dictionary is of type 'System.Collections.Generic.Lis传入字典的模型项的类型为 'System.Collections.Generic.List

【问题描述】：

调用索引视图给了我这个非常烦人的错误。谁能告诉我该怎么办

错误：传入字典的模型项的类型为“System.Collections.Generic.List1[MvcApplication13.Models.Groups]', but this dictionary requires a model item of type 'MvcApplication13.Helpers.PaginatedList1[MvcApplication13.Models.Groups]”。

public ActionResult Index(int?page) { 常量 int pageSize = 10; var group =from p in _db.Groups orderby p.int_GroupId select p;

      var paginatedGroup = group.Skip((page ?? 0) * pageSize).Take(pageSize).ToList();
      return View(paginatedGroup);            
    }

【问题讨论】：

我继承的东西可能有问题？

【解决方案1】：

粘贴代码时丢失了一些数据。这就是我认为您要粘贴的内容：查看

<%@ Page Title="" Language="C#" 
  MasterPageFile="~/Views/Shared/Site.Master" 
 Inherits="System.Web.Mvc.ViewPage<MvcApplication13.Helpers.PaginatedList<MvcApplication13.Models.Groups>>" %>

如果是这样，您的代码应该与此类似（即创建 PaginatedList 类的新实例）：

public ActionResult Index(int? page) {

    const int pageSize = 10;

    var upcomingDinners = dinnerRepository.FindUpcomingDinners();
    var paginatedDinners = new PaginatedList<Dinner>(upcomingDinners, page ?? 0, pageSize);

    return View(paginatedDinners);
}
