ViewBag in MVC

What is ViewBag

In my last article I explain how to send data from view to controller using ViewDataViewBag is also used to pass data from controller to its corresponding view. ViewBag used dynamic property which introduced in C# 4.0.
It is actually a dynamic ViewData Dictionary so you can say that it’s just a wrapper around ViewData.

ViewBag Example

Create a controller name Home and create view name Index. In this view create a list of type string in which stores the Department Name.

Code of Home Controller

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MvcApplication5.Controllers
    public class HomeController : Controller
        public ActionResult Index()
            List<string> dept = new List<string>()

            ViewBag.dept_name = dept;
            return View();


Code of Index View

In this example we create dynamic property named dept_name. Now use this ViewBag in View
    Layout = null;

<!DOCTYPE html>

    <meta name="viewport" content="width=device-width" />
        Employee Departments are:-<br />
        @foreach (string dept in ViewBag.dept_name)
As you can see that we need not to perform the type casting while working with ViewBag.
The output of this code will be as follows:-
