在foreach - umbraco中通过id获取媒体项目

Question

as I wrote in title I have problem with take Media in foreach.

This is my code:

@foreach (var item in @Model.Children.Where("Visible").OrderBy("UpdateDate"))
    {
        @{
            var link = new umbraco.cms.businesslogic.media.Media(item.MediaID).Children.FirstOrDefault().getProperty("umbracoFile").Value;
        }
        <div class="galleryListItem" style="background-image: url('/imageGen.ashx?image=@link&width=273&height=161');">
            <a href="@item.Url" class="link"></a>
            <div class="contentGalleryList">
                <div class="highlightGalleryList">@item.Name</div>
            </div>
        </div>
    }

and this line:

@link = new umbraco.cms.businesslogic.media.Media(item.MediaID).FirstOrDefault().getProperty("umbracoFile").Value;

give me this error:

Error loading MacroEngine script (file: GalleryList.cshtml);

What can I do to that start work? Maybe it's some better solve of this problem?

Any help would be appreciated.

I think something like this should work for you: (I'm not 100% sure what you code is trying to do, I've assumed the item.MediaID contains the id of a media item)

@foreach (var item in @Model.Children.Where("Visible").OrderBy("UpdateDate"))
{
    var media = Library.MediaById(item.MediaID);

       <div class="galleryListItem" style="background-image: url('/imageGen.ashx?image=@media.Url&width=273&height=161');">
        <a href="@item.Url" class="link"></a>
        <div class="contentGalleryList">
            <div class="highlightGalleryList">@item.Name</div>
        </div>
    </div>
}

There's also lots of great information on the our.umbraco.org wiki

Answer 2

I solve it. The problem was that I have open code section in other code section.

Working code:

@foreach (var item in @Model.Children.Where("Visible").OrderBy("UpdateDate"))
{
    var link = new umbraco.cms.businesslogic.media.Media(item.MediaID).Children.FirstOrDefault().getProperty("umbracoFile").Value;

    <div class="galleryListItem" style="background-image: url('/imageGen.ashx?image=@link&width=273&height=161');">
        <a href="@item.Url" class="link"></a>
        <div class="contentGalleryList">
            <div class="highlightGalleryList">@item.Name</div>
        </div>
    </div>
}
