如何将多个参数传递给MVC 4中的视图？ [英] How to pass multiple parameters to a view in MVC 4?

问题描述

嗨



我在ActionResult中传递两个列表变量如下所示。

Hi

I am passing two list variables in an ActionResult as Below.

public ActionResult Index()
        {
            List<category> cat = _business.ViewAllcat().ToList();
            List<Books> book = _business.ViewAllBooks().ToList();
            return View(book);
        }

当我运行代码时，我收到以下错误



传入字典的模型项的类型为'System.Collections.Generic.List`1 [Durgesh_Bhai.Models.category]'，但此字典需要一个类型为'System.Collections.Generic.IEnumerable的模型项`1 [Durgesh_Bhai.Models.Books]'。





但是当我在Actionresult中只使用一个List时它的工作正常。



请提供相同的解决方案，因为这是一项紧急要求。

When I run the Code I get the below error

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[Durgesh_Bhai.Models.category]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[Durgesh_Bhai.Models.Books]'.


But when I am using only one List in Actionresult its working fine.

Please provide the solution for the same as this is a urgent requirement.

推荐答案

你好，



我建议使用TupleList返回多个List并访问它。



只需执行以下操作即可... 。

Hello,

I Suggest to use TupleList for Return more than one List and access it.

Just do Following...

public ActionResult Index()
        {
            List<category> cat = _business.ViewAllcat().ToList();
            List<Books> book = _business.ViewAllBooks().ToList();

var objTuple=new Tuple<List<category>,List<Books>>(cat,book);
            return View(objTuple);
        }

// Access TupleList at Index.cshtml 
@model  Tuple<List<cat>,List<book>>

在这种情况下，最好使用ViewModel，创建一个包含require实体的viewmodel在View中并在控制器上设置值并将ViewModel传递给View。

Better you use ViewModel in this case , Create a viewmodel with require entities in your View and set values on controller and pass ViewModel to View.
