基本上我有一个网站,用户输入的图像标题,我想要在网站上显示它。该图像的标题。ASP.NET - C#MVC5
Atm 我保存到一个文件夹并显示所有图像但我不能显示标题。它只是当我没有出现<h2>@Html.DisplayFor(m => m.title)</h2>
这样的事情:但我想要的职位的标题。 https://i.gyazo.com/17828889116a77983f70fd8c8a4c2ebf.png
也许我需要将图像保存到数据库?请帮助我。
查看:
@foreach (var image in Model.Images)
{
<h2>@Html.DisplayFor(m => m.title)</h2>
<div class="row">
<div class="col-md-8 portfolio-item">
<img class="portrait" src="@Url.Content(image)" alt="Hejsan" />
</div>
</div>
}
