Asp.net mvc 3 如何在MVC3中添加列表并在同一视图中创建脚手架?
我使用的是mv3,iam正在创建应用程序,当我单击“创建”按钮时,需要将数据提交到数据库,并更新按钮下方的列表 我也尝试过局部查看,但显示错误: 传递到字典中的模型项的类型为 'System.Collections.Generic.List'1[MvcStudent.stu]',但 字典需要“MvcStudent.Models.StuModel”类型的模型项 我在plz帮助下面列出了我的代码 StudentController.csAsp.net mvc 3 如何在MVC3中添加列表并在同一视图中创建脚手架?,asp.net-mvc-3,partial-views,Asp.net Mvc 3,Partial Views,我使用的是mv3,iam正在创建应用程序,当我单击“创建”按钮时,需要将数据提交到数据库,并更新按钮下方的列表 我也尝试过局部查看,但显示错误: 传递到字典中的模型项的类型为 'System.Collections.Generic.List'1[MvcStudent.stu]',但 字典需要“MvcStudent.Models.StuModel”类型的模型项 我在plz帮助下面列出了我的代码 StudentController.cs public class StudentControl

错误告诉您需要知道的内容。再看一遍
传入字典的模型项的类型为“System.Collections.Generic.List`1[MvcStudent.stu]”,但此字典需要类型为“MvcStudent.Models.StuModel”的模型项
您正在将类型为System.Collections.Generic.List`1[MvcStudent.stu]
的对象从控制器传递到视图。您的视图需要类型为MvcStudent.Models.StuModel
的对象
再看看你的控制器-
public ActionResult create()
{
return View(stdb.stus.ToList());
}
因为您没有指定视图,所以它使用操作的名称来选择要尝试加载的视图-因此在本例中:Create
。“创建”视图在顶部包含此行
@model MvcStudent.Models.StuModel
这声明必须传递该类型的对象才能加载视图
这就解释了您所遇到的错误——在我看来,您似乎将“创建”视图与“列表”视图混合在一起。也许考虑把它们分开。我能做什么来保持在同一视图上创建和列表。我只想在表单加载和提交时从列表中的数据库中检索更新的数据。提交时,我正在将数据保存到数据库
