我仍然不太清楚如何在一个cshtml文件中使用信息,从另一个cshtml文件获取。我的节目由一个画廊组成。当用户点击其中一个图片时,我想重定向到另一个显示与该图片有关的图片和信息的视图,而不是简单地指向仅包含图片网址的页面。以下是我错误尝试的相关代码:
控制器:
public class HomeController : Controller
{
public ActionResult Index()
{
var client = new WebClient();
var response = client.DownloadString(Url.Action("gallery", "photo", null, Request.Url.Scheme));
var jss = new JavaScriptSerializer();
var result = jss.Deserialize<List<Photo>>(response);
return View();
}
public ActionResult FullImage(Photo m)
{
return View();
}
}
查看:
@section mainContent {
<ul class="thumbnails">
@foreach (var photo in Model)
{
<li class="item">
<a href='@Url.Action("FullImage", "Home", new {imageUrl="~/photos/" + photo.FileName, title= photo.Title, description= photo.Description})'>
<img alt="@photo.Description" src="@Url.Content("~/photos/" + photo.FileName)" class="thumbnail-border" width="180" />
</a>
<span class="image-overlay">@photo.Title</span>
</li>
}
</ul>
}
型号:
namespace PhotoGallery.Models
{
public class Photo
{
public string Title { get; set; }
public string FileName { get; set; }
public string Description { get; set; }
public string imageUrl { get; set; }
}
}

您无法使用操作链接绑定到模型。您需要将主键或唯一键传递给Action,并根据键在Action中找到您的Model。
例如,您可以在视图中执行此操作:
@section mainContent {
<ul class="thumbnails">
@foreach (var photo in Model)
{
<li class="item">
<a href='@Url.Action("FullImage", "Home", new { fileName = photo.FileName})'>
<img alt="@photo.Description" src="@Url.Content("~/photos/" + photo.FileName)" class="thumbnail-border" width="180" />
</a>
<span class="image-overlay">@photo.Title</span>
</li>
}
</ul>
}
然后,在你的行动中,你将拥有:
public ActionResult FullImage(string fileName)
{
// Example of some code to get the photo from the repository. It's better to use a photoID instead of the fileName.
var photo = db.Photos.FindPhoto(fileName);
return View();
}
