Get last child in array

I've recently started working with Umbraco and I'm trying to get the last child from an array. This is what I have done so far:

@inherits Umbraco.Web.Macros.PartialViewMacroPage

@{var page = Umbraco.Content(1127).Children[Children.Length - 1]}

<h5><a href='@page.Url'>@page.NewsTitle</a></h5>
<p>@page.NewsIntro</p>
<p class='read-more'><a href='@page.Url'>Read more...</a></p>

Edit:

Solution is as follows:

@inherits Umbraco.Web.Macros.PartialViewMacroPage

@{
    var length = Umbraco.Content(1127).Children.Count();
    var page = Umbraco.Content(1127).Children[length - 1];
}

<h5><a href='@page.Url'>@page.NewsTitle</a></h5>
<p>@page.NewsIntro</p>
<p class='read-more'><a href='@page.Url'>Read more...</a></p>

Umbraco has a bunch of "isHelpers" including IsLast(). Here is an exanple using isLast.

foreach(var page in Umbraco.Content(1127).Children)
{
    if(page.IsLast())
    {
        <h5><a href='@page.Url'>@page.NewsTitle</a></h5>
        <p>@page.NewsIntro</p>
        <p class='read-more'><a href='@page.Url'>Read more...</a></p>
    }
}

Here are some of the other isHelpers that Umbraco exposes.

IsHelper Methods .IsFirst([string valueIfTrue][,string valueIfFalse]) Test if current node is the first item in the collection

.IsNotFirst([string valueIfTrue][,string valueIfFalse]) Test if current node is not first item in the collection

.IsLast([string valueIfTrue][,string valueIfFalse]) Test if current node is the last item in the collection

.IsNotLast([string valueIfTrue][,string valueIfFalse]) Test if current node is not the last item in the collection

.IsPosition(int index[,string valueIfTrue][,string valueIfFalse]) Test if current node is at the specified index in the collection

.IsNotPosition(int index[,string valueIfTrue][,string valueIfFalse]) Test if current node is not at the specified index in the collection

.IsModZero([string valueIfTrue][,string valueIfFalse]) Test if current node position evenly dividable (modulus) by a given number

.IsNotModZero([string valueIfTrue][,string valueIfFalse]) Test if current node position is not evenly dividable (modulus) by a given number

.IsEven([string valueIfTrue][,string valueIfFalse]) Test if current node position is even

.IsOdd([string valueIfTrue][,string valueIfFalse]) Test if current node position is odd

.IsEqual(IPublishedContent otherNode[,string valueIfTrue][,string valueIfFalse]) Tests if the current node in your iteration is equivalent (by Id) to another node

.IsDescendant(IPublishedContent otherNode[,string valueIfTrue][,string valueIfFalse]) Tests if the current node in your iteration is a descendant of another node

.IsDescendantOrSelf(IPublishedContent otherNode[,string valueIfTrue][,string valueIfFalse]) Tests if the current node in your iteration is a descendant of another node or is the node

.IsAncestor(IPublishedContent otherNode[,string valueIfTrue][,string valueIfFalse]) Tests if the current node in your iteration is an ancestor of another node

.IsAncestorOrSelf(IPublishedContent otherNode[,string valueIfTrue][,string valueIfFalse]) Tests if the current node in your iteration is an ancestor of another node or is the node

If you're able to use Linq in your C# code I see there, it's got a "Last()" extension method you could use.

Like this:

        @using System.Linq
        @{var page = Umbraco.Content(1127).Children.Last()}

Try: @{var page = Umbraco.Content(1127).Children[Children.Length - 1]}

Do note the upper cased L in Length. c# is case sensitive, there is no array property named length.
