这是我的这个 View 的 Controller :
namespace FP.WebUI.Controllers
{
public class HomeController : Controller
{
private IInfoRepo repo;
public HomeController(IInfoRepo repoParam)
{
repo = repoParam;
}
public ViewResult Index()
{
Info model = repo.Info.FirstOrDefault();
return View(model);
}
}
}
这是 View 本身:
@model FP.Domain.Entities.Info

Layout = null;
