Question

The following snippet gives me an error:

@foreach (PageViewModel root in menuData)
    {
        Action < PageViewModel > traverse = null;
        traverse = (n) => {
            @<text>
                <li><a href="@n.Url">@n.Title</a></li>
            </text>
            n.Children.ForEach(traverse);
        };
        traverse(root);
    }

The error is: CS1002: ; expected, right on the line after the </text> closing tag.

What am I doing wrong here?

You could try making your code snippet into a Templated Razor Delegate.

Based on Phil Haack’s example, you could make a helper that looked something like:

public static class RazorExtensions 
{
    public static HelperResult Traverse(this Action<PageViewMoidel> traverse, 
        Func<T, HelperResult> template) 
    {
        return new HelperResult(writer => 
        {
            traverse = (n) => template(n).WriteTo(writer);
        });
    }
}

Disclaimer: I haven’t tested this and have conveniently omitted the call to n.Children.Foreach for simplification.
