Controller:

public ActionResult Details(int id = 0)
            {
                Persons p= db.persons.Find(id);

                var query = from a in db.images
                            where a.Id_Person== id
                            select a.FileName;
                ViewBag.ImgRev= query;

                if (mag == null)
                {
                    return HttpNotFound();
                }

                return View(p);
            }

View:

@foreach (var p in ViewBag.ImgRev)
        { 
          <div>
            <img src="~/Files/" + @p /></div>
        }

linq 语句在分配给ViewBag.

尝试：

控制器：

ViewBag.ImgRev = query.ToList();

看法：

@ {
    var imgList = ViewBag.ImgRev as IEnumerable<string>;
}

@foreach (var p in imgList)
{ 
    <div><img src="~/Files/" + @p /></div>
}

使用 ViewModel 的替代方案：

public class SomePageViewModel
{
    public Persons Persons { get; set; }
    public IEnumerable<string> Files { get; set; }
}

控制器：

...
var model = new SomePageViewModel { Persons = p, Files = query.ToList() };
return model;

看法：

@foreach (var file in Model.Files)
{ 
    <div><img src="~/Files/" + @file /></div>
}
