In Model

1. Firstly create model class named Course and create property
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;

namespace StudentRecord.Models
{
    public class Course
    {

        public int CourseId { get; set; }

        [Display(Name = "Course Name")]
        [Required(ErrorMessage = "Enter Course Name")]
        public string CourseName { get; set; }
    }
}

2. Then create another model class named as u wish. Here we use connection string and stored procedure.but i am using dll class here for connectivity.
 
 public class DbConnectivity
    {
        private static string Config = System.Configuration.ConfigurationManager.ConnectionStrings["strCon"].ConnectionString;

 public List<Course> DropCourse()
        {
            Database db = new SqlDatabase(Config);
            DbCommand dbCommand = db.GetStoredProcCommand("DISPLAYCOURSE");
            List<Course> list = new List<Course>();
            using (IDataReader dataReader = db.ExecuteReader(dbCommand))
            {
                while (dataReader.Read())
                {
                    Course obj = new Course();
                    if (dataReader["Course"] != DBNull.Value)
                    {
                        if (dataReader["Course"] != DBNull.Value) { obj.CourseId = (int)dataReader["Course"]; }
                        if (dataReader["COURSENAME"] != DBNull.Value) { obj.CourseName = (string)dataReader["COURSENAME"]; }
                        list.Add(obj);
                    }
                }
                return list;
            }
        }
}
3.
In Controller
 public ActionResult Drop()
        {
            DbConnectivity dbconnection = new DbConnectivity();
            List<Course> pcontent = new List<Course>();
            {
                //Get all page content from TblHome table
                pcontent = dbconnection.DisplayCourse();

            };
            List<SelectListItem> cityList = new List<SelectListItem>();
            //List<string> items = new List<string>();
            foreach (var item in pcontent)
            {
                cityList.Add(new SelectListItem
                {
                    Text = item.CourseName,
                    Value = item.CourseId.ToString()
                });
            }
          
            ViewBag.CityList = cityList;
            return View();


            //return View(pcontent);
        }


In  public ActionResult Drop()
        {
            DbConnectivity dbconnection = new DbConnectivity();
            List<Course> pcontent = new List<Course>();
            {
                //Get all page content from TblHome table
                pcontent = dbconnection.DisplayCourse();

            };
            List<SelectListItem> cityList = new List<SelectListItem>();
            //List<string> items = new List<string>();
            foreach (var item in pcontent)
            {
                cityList.Add(new SelectListItem
                {
                    Text = item.CourseName,
                    Value = item.CourseId.ToString()
                });
            }
          
            ViewBag.CityList = cityList;
            return View();


            //return View(pcontent);
        }

In View

@model StudentRecord.Models.Course

@{
    ViewBag.Title = "Drop";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Drop</h2>


<fieldset>
    <legend>Course</legend>

    <div class="display-label">CourseName</div>
    <div class="display-field">
