An Image Gallery Application In MVC 4

I am showing this functionality by creating an ASP.Net MVC 4 application (R- An Image Gallery Application In MVC 4).

The following is my SQL Server Data Table structure: (Album_Details).

design view
                                       Image 1.

Now open Visual Studio and select "File" -> "New" -> "Project...":

New Project
                                                                        Image 2.

internet application
                                                                        Image 3.

Now right-click on the Model Folder Add New Item -> Add New Class (ImageInfo):

  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Web;  
  5.   
  6. namespace AnImageGalleryApplicationInMVC4.Models  
  7. {  
  8.     public class ImageInfo  
  9.     {  
  10.         public int Image_Id { get; set; }  
  11.         public string Image_Name { get; set; }  
  12.         public byte[] Image { get; set; }  
  13.         public string Image_UploadedDate { get; set; }  
  14.     }  
  15. }  
Now again right-click on the Model Folder-> Add New Item -> Add New Class (RAlbumService):
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Web;  
  5. using System.Data;  
  6. using System.Data.SqlClient;  
  7. using System.Configuration;  
  8. using System.IO;  
  9.   
  10. namespace AnImageGalleryApplicationInMVC4.Models  
  11. {  
  12.     public class RAlbumService  
  13.     {  
  14.         public IList<ImageInfo> GetAllImages()

  17.             SqlDataAdapter da;  
  18.             DataSet ds = new DataSet();  
  19.             SqlConnection con = new SqlConnection();  
  20.             con.ConnectionString = @"Data Source=MYPC\SqlServer2k8;Integrated Security=true;Initial Catalog=R-ImageGallery";  
  21.             SqlCommand cmd = new SqlCommand("SELECT * FROM Album_Details", con);  
  22.             da = new SqlDataAdapter(cmd);  
  23.             da.Fill(ds);  
  24.             con.Open();  
  25.             cmd.ExecuteNonQuery();  
  26.             con.Close();  
  27.             if (!object.Equals(ds.Tables[0], null))  
  28.             {  
  29.                 if (ds.Tables[0].Rows.Count > 0)  
  30.                 {  
  31.   
  32.                     for (int i = 0; i < ds.Tables[0].Rows.Count; i++)  
  33.                     {  
  34.                         ImageInfo objThisIMGInfo = new ImageInfo();  
  35.                         objThisIMGInfo.Image_Id = Convert.ToInt32(ds.Tables[0].Rows[i]["IMG_ID"]);  
  36.                         objThisIMGInfo.Image_Name = ds.Tables[0].Rows[i]["ImageName"].ToString();  
  37.                         objThisIMGInfo.Image = (byte[])ds.Tables[0].Rows[i]["Photo"];  
  38.   
  39.   
  40.                         objThisIMGInfo.Image_UploadedDate = ds.Tables[0].Rows[i]["UploadedDate"].ToString().Split(' ')[0];    
  41.   
  42.                         objImgInfo.Add(objThisIMGInfo);  
  43.                     }  
  44.                       
  45.                 }  
  46.             }  
  47.             return objImgInfo.ToList();  
  48.         }  
  49.   
  50.         public byte[] GetImageDetails(int id)  
  51.         {  
  52.             SqlConnection con = new SqlConnection(@"Data Source=MYPC\SqlServer2k8;Integrated Security=true;Initial Catalog=R-ImageGallery");  
  53.             using (SqlCommand cmd = new SqlCommand())  
  54.             {  
  55.                 cmd.Connection = con;  
  56.                 cmd.CommandType = CommandType.Text;  
  57.                 cmd.CommandText = "SELECT Photo FROM Album_Details where IMG_ID=@ImageId";  
  58.                 cmd.Parameters.AddWithValue("@ImageId", id);  
  59.                 con.Open();  
  60.                 SqlDataReader dr = cmd.ExecuteReader();  
  61.                 ImageInfo objImageInfo = new ImageInfo();  
  62.                 while (dr.Read())  
  63.                 {  
  64.                     objImageInfo.Image = (byte[])dr["Photo"];  
  65.                 }  
  66.                 return objImageInfo.Image;  
  67.             }  
  68.         }  
  69.   
  70.         public int UploadImage(ImageInfo objImageInfo)  
  71.         {  
  72.             SqlConnection con = new SqlConnection(@"Data Source=MYPC\SqlServer2k8;Integrated Security=true;Initial Catalog=R-ImageGallery");  
  73.             using (SqlCommand cmd = new SqlCommand())  
  74.             {

  76.                 cmd.CommandType = CommandType.Text;  
  77.                 cmd.CommandText = "INSERT INTO Album_Details(ImageName,Photo) VALUES(@ImageName,@Photo)";  
  78.                 cmd.Parameters.AddWithValue("@ImageName", objImageInfo.Image_Name);  
  79.                 cmd.Parameters.AddWithValue("@Photo", objImageInfo.Image);  
  80.                 con.Open();  
  81.                 int result = cmd.ExecuteNonQuery();  
  82.                 con.Close();  
  83.                 return result;  
  84.             }  
  85.         }  
  86.     }  
  87. }  
Now right-click on Controller -> Add New Controller (Albums):
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Web;  
  5. using System.Web.Mvc;

  7. using System.IO;  
  8.   
  9. namespace AnImageGalleryApplicationInMVC4.Controllers  
  10. {  
  11.     public class AlbumsController : Controller  
  12.     {  
  13.         RAlbumService objAlbumModelService = new RAlbumService();  
  14.   
  15.         [HttpGet]          
  16.         public ActionResult Index()  
  17.         {  
  18.             ViewBag.total = objAlbumModelService.GetAllImages().ToList().Count;  
  19.             return View(objAlbumModelService.GetAllImages().ToList());  
  20.         }  
  21.   
  22.         public ActionResult GetImgInformation(int id)  
  23.         {  
  24.             byte[] cover = objAlbumModelService.GetImageDetails(id);  
  25.             if (cover != null)  
  26.             {  
  27.                 return File(cover, "image/jpg");  
  28.             }  
  29.             else

  32.             }  
  33.         }  
  34.   
  35.   
  36.         [HttpPost]  
  37.         public ActionResult Index(FormCollection collection)  
  38.         {  
  39.             HttpPostedFileBase file = Request.Files["ImageData"];  
  40.             ImageInfo objAlbumMaster = new ImageInfo();  
  41.             objAlbumMaster.Image_Name = collection["ImageName"].ToString();  
  42.             objAlbumMaster.Image = ConvertToBytes(file);  
  43.             objAlbumModelService.UploadImage(objAlbumMaster);

  52.             return imageBytes;  
  53.         }  
  54.     }  
  55. }  
Now right-click on the Index Method name add new view and do the following code:
