razor count items

Question

How can i do this in razor:

• when there is one item, i only want this item to be displayed. (item in fotoGallerij)
• when there are more items, i want all of them (like the code bellow, working)

How can i make this if (i think) structure in razor (c# / umbraco)?

@inherits umbraco.MacroEngines.DynamicNodeContext

<ul class="image-gallery">
@foreach (var item in @Model.fotoGallerij)
{
<li>
<a class="gallery grouped" href="/ImageGen.ashx?height=500&amp;constrain=true&amp;crop=resize&amp;[email protected]" title="">

<img src="/ImageGen.ashx?width=71&amp;height=73&amp;crop=resize&amp;[email protected]" alt=""/></a>
 </li>
 }
</ul>
 <script>
    $("a.gallery").colorbox({rel:'grouped'});
</script>

Thanks for helping!

Solution

Razor is in effect C#, so anything you can do with C#, you can do with Razor. Something like this should work:

@inherits umbraco.MacroEngines.DynamicNodeContext
@if (Model.fotoGallerij.Count() == 1)
{
    // Display only the one here...
}
else if (Model.fotoGallerij.Count() > 1)
{
    // Loop through the list of items here...
}

Compiler Error Message: CS1061: 'MVCApp3.Models.CompanyListView' does not contain a definition for 'Count' and no extension method 'Count' accepting a first argument of type 'MVCApp3.Models.CompanyListView' could be found (are you missing a using directive or an assembly reference?)

@JulesBartow, the code above is in reference to umbraco. Model.fotoGallerij is handled by umbraco dynamically and returns a DynamicNodeList which does have a Count method associated with it. This wouldn't apply to a standard MVC app.
