8/03/2017 - By Pranav Singh 0

This artilce will show you how to insert data into database using entity framework in Asp.net mvc. This article will help on entity framework 6 insert record, Save Form Data to Database using Model in ASP.NET.

So for this article first we will create a new table.


Now check the data currently present in my table.

Now we will create a new asp.net mvc application and add an entity file and import your table in 
Now we will add a new model class file and the below code.

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

namespace MVC_Demos.Models
{
    public class Student
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Address { get; set; }
        public string Section { get; set; }
        public string Marks { get; set; }
    }
}

Now we will add a controller class file and add the below code.

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

namespace MVC_Demos.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /Home/
        [HttpGet]
        public ActionResult Index()
        {
            Student _studentModel = new Student();
            return View(_studentModel);
        }

        [HttpPost]
        public ActionResult Index(Student _studentModel)
        {
            try
            {
                DemoEntities _demoEntities = new DemoEntities();
                StudentDetail stu = new StudentDetail();

                stu.Id = _studentModel.Id;
                stu.Name = _studentModel.Name;
                stu.Marks = Convert.ToInt32(_studentModel.Marks);
                stu.Section = _studentModel.Section;
                stu.Address = _studentModel.Address;

                _demoEntities.StudentDetails.Add(stu);
                _demoEntities.SaveChanges();

                ViewBag.Message = "Data saved successfully.";
            }
            catch
            {
                ViewBag.Message = "Error while saving record.";
            }
            return View(_studentModel);
        }
    }
}


Now in above code just check highlighted part of the code. In above code first we have created the instance of the entity and then instance for the entity table. After creating instance I have assign the model value to entity table object.

After that I have added the entity table to the entity object. Now I have save the entity changes.

Note:  Here we need take care at in SQL table that we must have the primary key field on out table.

Now we have done run the application and check the output.



Now click on save button and check your table where you saved the detail.
