I am using the Auros categorisation package and I am having issues with some functionality that uses the .SKIP method. Namely, the following piece of code

var pagesToList = NodeHelpers.GetNodesInCategory("Testimonial",Convert.ToInt32(Request["c"],0));var numberOfItems = pagesToList.Count();
currentPage--;
var numberOfPages = numberOfItems % itemsPerPage == 0 ? Math.Ceiling((decimal)(numberOfItems / itemsPerPage)) : Math.Ceiling((decimal)(numberOfItems / itemsPerPage))+1;
var Pages = Enumerable.Range(1, (int)numberOfPages);

@foreach(var item in pagesToList.Skip(currentPage*itemsPerPage).Take(itemsPerPage))
{
}

Is giving me the following error message: error CS1973: 'umbraco.NodeFactory.Node[]' has no applicable method named 'Skip' but appears to have an extension method by that name. Extension methods cannot be dynamically dispatched. Consider casting the dynamic arguments or calling the extension method without the extension method syntax.

I just can't work out how to cast the pagesToList variable so that the .Skip functionality will work, which is being used for paging purposes. Does anyone have any idea as to how I can accomplish this?
