Question

I have a model that contains a Byte[] type property .I want to display this property in MVC View in html tag.What approach I can use to display this image?

Answer 1

Create an action on your controller to return the file response:

public class MyController : Controller
{
    public ActionResult ViewFile()
    {
        byte[] bytes;
        string mime;

        return File(bytes, mime);
    }
}

You can then display the image like so:

<img src="/mycontroller/viewfile" />

EDIT:
A detailed example:

public class Photo
{
    public int ID {get;set;}
    public string Title {get;set;}
}

public class PhotoController : Controller
{
    public ActionResult Index()
    {
        return View(new List<Photo> { new Photo { ID = 1, Title = "first" }, new Photo { ID = 2, Title = "second" }});
    }
    public ActionResult Photo(int ID)
    {
        return File(GetPhotoBytes(ID), "image/jpg");
    }
}

View:

@model IEnumerable<Photo>
@foreach (var photo in Model)
{   
    <img src="@Url.Action("photo", "photo", new { ID = photo.ID })" title="@photo.Title" /> 
}
