How to use the @Model?

I have "test" variable that has the following properties: test variable

Can someone please explain to me why test.Title gives this error: fail error

Here is the full code snippet:

@foreach (var category in Model.CategoryBlocks)
    {
        <div class="col-lg-4 col-md-6 mb-4">
            <div class="card h-100">
                <div class="card-body">
                    @{
                        var test = @category.Content;
                        //var d = test.Title;
                        var c = 0;
                    }
                    <h2 class="card-title">@category.Content</h2>
                    <p class="card-text">@*@category.CategoryBlurb*@</p>
                    <a href="#" class="btn btn-primary">Show More</a>
                </div>
            </div>
        </div>
    }

Hi there!

I know why you cannot access the title property. The return type of @category.Content is IPublishedElement. Like the error says: This type does not have a property 'Title'. You have to explicitly tell the compiler that this is a CategoryBlock. You can do that with a type cast

Cast type or use the .Value method.

@foreach (var category in Model.CategoryBlocks)
{
    <div class="col-lg-4 col-md-6 mb-4">
        <div class="card h-100">
            <div class="card-body">
                @{
                    var test = @category.Content;

                    //Solution 1 (type cast from IPublishedContent to CategoryBlock)
                    //var d = ((CategoryBlock)test).Title;

                    //Solution 2 (use the Value method)
                    //var d = test.Value("title");

                    var c = 0;
                }
                <h2 class="card-title">@category.Content</h2>
                <p class="card-text">@*@category.CategoryBlurb*@</p>
                <a href="#" class="btn btn-primary">Show More</a>
            </div>
        </div>
    </div>
}
