ASP.Net MVC - Img Src Server Path

I am having troubles displaying an image from a server path which is stored in a database.
我在显示来自存储在数据库中的服务器路径的图像时遇到问题。
I am using HttpPostedFileBase to retrieve the file the user has uploaded:
我正在使用 HttpPostedFileBase 来检索用户上传的文件：
using (var uow = _db.CreateUnitOfWork())
{
if (imageUpload != null && imageUpload.ContentLength > 0)
{
var fileName = Path.GetRandomFileName() + Path.GetExtension(imageUpload.FileName);
var path = Path.Combine(System.Web.Hosting.HostingEnvironment.MapPath("~/Uploads"), fileName);
imageUpload.SaveAs(path);
achievement.ImageLoc = path;
}
uow.Add(achievement);
Save(uow);
return true;
}
This will save the absolute path of the uploaded file into the database and save the file onto the server. When I try to retrieve this path to display an image file in a view all I get is a blank square like the file is not being found (about:blank when right click -> copy image url). I know the path is correct because I am using it in a different view to allow users to download files, which is working correctly. Also I am allowing the user to edit the file which successfully deletes the old and uploads a new one. The only problem I am having is displaying an image in a view.
这会将上传文件的绝对路径保存到数据库中，并将文件保存到服务器上。当我尝试检索此路径以在视图中显示图像文件时，我得到的只是一个空白方块，就像未找到该文件一样（about:blank when right click -> copy image url）。我知道路径是正确的，因为我在不同的视图中使用它来允许用户下载文件，这是正常工作的。此外，我允许用户编辑成功删除旧文件并上传新文件的文件。我遇到的唯一问题是在视图中显示图像。
I have tried:
我试过了：
<img src="@Html.Encode(Model.ImageLoc)" />
<img [email protected](Model.ImageLoc)" />
Would anyone be able to suggest anything?
任何人都可以提出任何建议吗？

You have stored the absolute path to the image in your database, but you need to reference it with the relative path:
您已将图像的绝对路径存储在数据库中，但您需要使用相对路径来引用它：
<img src="@Url.Content("~/Uploads/" + System.IO.Path.GetFileName(Model.ImageLoc))" alt="" />
The resulting HTML must look like this:
生成的 HTML 必须如下所示：
<img src="/Uploads/tccxdfu0.nde.jpg" alt="" />
and not:
并不是：
<img src="\PDC2\sites\t\<site.co.uk>\public_html\Uploads\tccxdfu0.nde.jpg" alt="" />
because the client cannot access such folders from the server.
因为客户端无法从服务器访问此类文件夹。
