问题描述

按 ViewBag ？

如何解决这个错误的数据传递给视图

  

类型'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException的异常出现在System.Core.dll但在用户code没有处理

的定义

在控制器

  VAR LINQ =（从C在db.Catogeries
            在db.Articals加入上c.Id等于a.CatogeryId
            选择新的{名= c.Name，标题= a.Title}）;
ViewBag.data = LINQ;
 

在View

  @ {
     的foreach（在ViewBag.data VAR项）
     {
          ＆所述p为H.; @ item.name＆下; / P＆GT;
     }
}
 

解决方案

的简单的方式来解决这个错误产生的一类，而不是使用匿名对象，并使用强类型的模型。

  VAR LINQ =（从C在db.Catogeries
        在db.Articals加入上c.Id等于a.CatogeryId
        选择新的MyCategory {名= c.Name，标题= a.Title}）;ViewBag.data = LINQ;
 

在查看：

 的foreach（在（IEnumerable的＆LT VAR项目; MyCategory＆GT;）ViewBag.data）
{
     ＆所述p为H.; @ item.name＆下; / P＆GT;
}

How can solve this error to pass data to the view by ViewBag?

An exception of type 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' occurred in System.Core.dll but was not handled in user code

Additional information: 'object' does not contain a definition for 'name'

In Controller

var linq = (from c in db.Catogeries
            join a in db.Articals on c.Id equals a.CatogeryId
            select new  {name=c.Name,title=a.Title });
ViewBag.data = linq;

In View

@{         
     foreach (var item in ViewBag.data )
     {
          <p>@item.name</p>
     }
}

解决方案

The simplest way to fix this error creating a class instead of using anonymous object and use strongly-typed model.

var linq = (from c in db.Catogeries
        join a in db.Articals on c.Id equals a.CatogeryId
        select new MyCategory { name=c.Name, title=a.Title });

ViewBag.data = linq;

In View:

foreach (var item in (IEnumerable<MyCategory>)ViewBag.data )
{
     <p>@item.name</p>
}
