Store Photo In Backend Using Entity Framework In MVC Razor And Bootstrap

Introduction

Using MVC and Bootstrap, the images can be stored and retrieved in different types of View.

Description

Here, I will show you how image details can be shown along with the username. Let's take a sample example of student management system in MVC and Bootstrap.

Steps to be followed -

Step 1

Create an MVC application named "SatyaImageMvcUpload".

 
 
Step 2

Create one table named "tblStudent".

SQL Script for table -
  1. SET ANSI_NULLS ON  
  2. GO  
  3.   
  4. SET QUOTED_IDENTIFIER ON  
  5. GO  
  6.   
  7. CREATE TABLE [dbo].[tblStudent](  
  8.     [StudentId] [int] IDENTITY(1,1) NOT NULL,  
  9.     [FirstName] [nvarchar](50) NULL,  
  10.     [LastName] [nvarchar](50) NULL,  
  11.     [ImageUrl] [nvarchar](50) NULL,  
  12. PRIMARY KEY CLUSTERED   
  13. (  
  14.     [StudentId] ASC  
  15. )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON)   
  16.   
  17. ON [PRIMARY]  
  18. ) ON [PRIMARY]  
  19.   
  20. GO 
Step 3

Create one Entity model that contains the table parameters, named "StudentDataModel.edmx".

 
Step 4

Then, let's create a Controller class file named as "HomeController.cs".

Code Ref
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Web;  
  5. using System.Web.Mvc;  
  6.   
  7. namespace ImageuploadingDemo.Controllers  
  8. {  
  9.     public class HomeController : Controller  
  10.     {  
  11.         public ActionResult Index()  
  12.         {  
  13.             return View();  
  14.         }  
  15.   
  16.         public ActionResult FileUpload(HttpPostedFileBase file)  
  17.         {  
  18.             if (file != null)  
  19.             {  
  20.                 StudentEntities db = new StudentEntities();  
  21.                 string ImageName = System.IO.Path.GetFileName(file.FileName);  
  22.                 string physicalPath = Server.MapPath("~/Images/" + ImageName);  
  23.                 file.SaveAs(physicalPath);  
  24.                 tblStudent student = new tblStudent();  
  25.                 student.FirstName = Request.Form["firstname"];  
  26.                 student.LastName = Request.Form["lastname"];  
  27.                 student.ImageUrl = ImageName;  
  28.                 db.tblStudents.Add(student);  
  29.                 db.SaveChanges();  
  30.   
  31.             }  
  32.             return RedirectToAction("../home/DisplayImage/");  
  33.         }  
  34.   
  35.         public ActionResult DisplayImage()  
  36.         {  
  37.             return View();  
  38.         }  
  39.   
  40.     }  
  41. } 
Code Description

The below-mentioned code defines how to insert records to the respected parameters and how after successful insertion, the page will redirect to the details or displayimage View page. 
  1. public ActionResult FileUpload(HttpPostedFileBase file)  
  2.         {  
  3.             if (file != null)  
  4.             {  
  5.                 StudentEntities db = new StudentEntities();  
  6.                 string ImageName = System.IO.Path.GetFileName(file.FileName);  
  7.                 string physicalPath = Server.MapPath("~/Images/" + ImageName);  
  8.                 file.SaveAs(physicalPath);  
  9.                 tblStudent student = new tblStudent();  
  10.                 student.FirstName = Request.Form["firstname"];  
  11.                 student.LastName = Request.Form["lastname"];  
  12.                 student.ImageUrl = ImageName;  
  13.                 db.tblStudents.Add(student);  
  14.                 db.SaveChanges();  
  15.   
  16.             }  
  17.             return RedirectToAction("../home/DisplayImage/");  
  18.         } 
Step 5
 
Here, I have created two Views - Index and DisplayImage - under the Home Controller file. Index View is created to insert the records and the DisplayImage View is for showing the details of student information with images.
