ASP.NET MVC image from byte array

One way is to add this to a new c# class or HtmlExtensionsclass

public static class HtmlExtensions
{
    public static MvcHtmlString Image(this HtmlHelper html, byte[] image)
    {
        var img = String.Format("data:image/jpg;base64,{0}", Convert.ToBase64String(image));
        return new MvcHtmlString("<img src='" + img + "' />");
    }
}

then you can do this in any view

@Html.Image(Model.MyImageBytes)

You could define a controller action that will serve the image:

public class ImagesController: Controller
{
    public ActionResult Index(int id)
    {
        byte[] imageData = ... go get your image data from the id
        return File(imageData, "image/png"); // Might need to adjust the content type based on your actual image type
    }
}

and in your view simply point the src property of the img tag to this controller action:

<img src="@Url.Action("Index", "Images", new { id = Model.Id })" />
