How can I do this in Razor

[RemcoW2002]

Might be a bit of a nooby question again but I can't figure out to check if the count of contentItem is above 0 in the Search-Results.cshtml:

@if (Model.ContentItems != null && Model.ContentItems.Length > 0)

I've tried Count, Length, Size, HasItems which of course doesn't work.

Also this is one of the places in the docs where I think a razor example is missing:
https://docs.orchardcore.net/en/main/guides/implement-fulltext-search/#:~:text=FlowPart.Widgets%20%7C%20full_text_aspect%20%7D%7D-,Optional%20%3A%20Search%20templates%20customization,-%C2%B6

As you can see in the above this is how it's done in liquid:

{% if Model.ContentItems != null and Model.ContentItems.size > 0 %}
    <ul class="list-group">
        {% for item in Model.ContentItems %}
            <li class="list-group-item">
                {{ item | shape_build_display: "SearchSummary" | shape_render }}
            </li>
        {% endfor %}
    </ul>
{% elsif Model.Terms != null %}
    <p class="alert alert-warning">{{"There are no such results." | t }}</p>
{% endif %}

Edit: I've currently fixed this by doing this, but surely there is a better way?

    if (Model.ContentItems != null)
    {
        try
        {
            // Try accessing as a List
            resultCount = Model.ContentItems.Count;
            hasResults = resultCount > 0;
        }
        catch
        {
            try
            {
                // Try accessing as an Array
                resultCount = Model.ContentItems.Length;
                hasResults = resultCount > 0;
            }
            catch
            {
                // Default to false if both fail
                hasResults = false;
            }
        }
    }
}

@if (hasResults)
{ ....

There's SearchIndexViewModel, then what you need to do is

@if (Model.SearchResults is null)
{
    <div class="alert alert-primary">No results found.</div>
}
else
{
    ....
}
