Question

I am using EF 4.1 Code First and for the sake of simplicity, let’s say I have the following Entity class:

public class Person
{
    public int Id { get; set; }
    public string Name { get; set; }
    public Byte[] Image { get; set; }
}

I have managed to create a working Create View that allows the Addition of a Person object into the Database.

But when I come to display the details for a Person, I get stuck on displaying the image. After doing some research, I have the following:

// To convert the Byte Array to the author Image
public FileContentResult getImg(int id)
{
    byte[] byteArray = DbContext.Persons.Find(id).Image;
    return byteArray != null 
        ? new FileContentResult(byteArray, "image/jpeg") 
        : null;
}

And in the View where I am attempting to list the Person details, I have the following to get the Image to display:

<img src="@Html.Action("getImg", "Person", new { id = item.Id })" alt="Person Image" />

However the above is not working, my image source [src] attribute returns empty.

Like this:

<img src="@Url.Action("getImg", "Person", new { id = item.Id })" alt="Person Image" />

You need Url.Action and not Html.Action because you just want to generate an url to the GetImg action. Html.Action does something entirely different.
