c# - How to display database image (bytes[]) in mvc WebGrid -


i'm trying display byte[] image database in .net mvc webgrid column. i`m doing following steps

(ef model - articulos) 

[key]     public int id_art { get; set; }      public int id_pro { get; set; }      [stringlength(1)]     public string tipo_pro { get; set; }      [required]     [stringlength(50)]     public string nombre_pro { get; set; }      [required]     [stringlength(100)]     public string descripcion_pro { get; set; }      public byte[] imagen_pro { get; set; }      [required]     public decimal? precio_pro { get; set; }      public int? estatus_pro { get; set; }

(controller)

public list<articulos> cargararticulos(string search, string sort, string sortdir, int skip, int pagesize, out int totalrecord)     {         using (dbmodel db = new dbmodel())         {             var v = (from in db.articulos                                               a.tipo_pro.contains(search) ||                         a.nombre_pro.contains(search) ||                         a.descripcion_pro.contains(search)                      select                      );             totalrecord = v.count();             v = v.orderby(sort + " " + sortdir);             if (pagesize > 0)             {                 v = v.skip(skip).take(pagesize);             }             return v.tolist();         }     }

(view)

<div>             @grid.table(                     tablestyle: "table table-responsive table-bordered",                     headerstyle: "webgrid-header",                     footerstyle: "webgrid-footer",                     alternatingrowstyle: "webgrid-alternating-row",                     rowstyle: "webgrid-row-style",                     columns: grid.columns(                         grid.column(columnname: "imagen_pro", header: "imagen", format: ),                         grid.column(columnname: "tipo_pro", header: "tipo"),                         grid.column(columnname: "nombre_pro", header: "nombre"),                         grid.column(columnname: "descripcion_pro", header: "descripcion"),                         grid.column(columnname: "precio_pro", header: "precio"),                         grid.column(header: "⇨", format: (item) => html.actionlink("ver", "ver", new { }))     ) )

everything else works fine, i'm succesfully retrieving list controller, , displays webgrid, problem display byte[] image stored in database, don´t know how convert base64 before display in webgrid or adding righ format in column. i've been working on hours, please help.

grid.column(columnname: "imagen_pro", header: "imagen", format: ),

here's approach converting byte array base64 , embedding base64 string in img tag in grid. should able add static method controller this:

public static string convertbytearraytobase64(int id) {     using (var db = new dbmodel())     {         return convert.tobase64string(db.articulos.where(c => c.id_art == id).first().imagen_pro);     } }

then add column this:

columns: grid.columns (     grid.column(header: "imagen", format: @<img src="data:image/jpeg;base64,@yourcontroller.convertbytearraytobase64(@item.id_art)" alt="">)) )

if it's png or gif, replace image/jpeg image/png or image/gif respectively.
