Question

Is there any property or function for DynamicNodeList which returns the number of list items.

This is my code:

var root = Model.NodeById(id);
var nodes = root.Descendants("ChartItem");

if (nodes.GetLength() > 0)
{
   s = s + "<ul>";
}

But GetLength is not a valid function. what should I do?

Answer 1

There is a built in extension method for IEnumerable types called Count(), it does just that, it counts the items 🙂

See code below:

var root = Model.NodeById(id);
var nodes = root.Descendants("ChartItem");

if (nodes.Count() > 0)
{
    s = s + "<ul>";
}
