Getting Last Item in related links (Umbraco 7)

Been trying to find the last related link within a foreach loop. But there doesn't seem to be any Last() or IsLast() methods available. Does anyone know a way around this without having to use a count loop. Code and error below:

@{
if (root.HasValue("relatedLinks") && root.relatedLinks.ToString().Length > 2)
{

    <ul>
        @foreach (var item in root.relatedLinks)
        {
            var test = root.relatedLinks;


            var linkUrl = (bool)item.isInternal ? Umbraco.NiceUrl(item.Value<int>("internal")) : item.link;
            var linkTarget = (bool)item.newWindow ? "_blank" : null;

            <li><a href="@linkUrl" target="@linkTarget">@item.caption</a></li>

            if (item.IsLast()) { <li>Do this</li>}

        }
    </ul>
}

'Newtonsoft.Json.Linq.JObject' does not contain a definition for 'IsLast'.

Thanks in advance for your help.

Just done a bit more research and developed the following solution but I still think there could be better solution without having to go through two loops.

@{
if (root.HasValue("relatedLinks") && root.relatedLinks.ToString().Length > 2)
{
    dynamic jObj = Newtonsoft.Json.JsonConvert.DeserializeObject(root.relatedLinksToString());
    int count = jObj.Count;
    int loopcount = 0;
    <ul>
        @foreach (var item in root.relatedLinks)
        {   
            var linkUrl = (bool)item.isInternal ? Umbraco.NiceUrl(item.Value<int>("internal")) : item.link;
            var linkTarget = (bool)item.newWindow ? "_blank" : null;

            <li><a href="@linkUrl" target="@linkTarget">@item.caption</a></li>
            loopcount++;
            if (loopcount == count) { } else {<li>|</li> } 
        }
    </ul>
}

}

Hi, I would do something like this:

@{
    if (Model.Content.HasValue("relatedLinks") && Model.Content.GetPropertyValue<string>("relatedLinks").Length > 2)
    {
        <ul>
            @{
                var relatedLinks = Model.Content.GetPropertyValue<JArray>("relatedLinks");
                foreach (var item in relatedLinks)
                {
                    var linkUrl = (item.Value<bool>("isInternal")) ? Umbraco.NiceUrl(item.Value<int>("internal")) : item.Value<string>("link");
                    var linkTarget = item.Value<bool>("newWindow") ? "_blank" : null;
                    <li><a href="@linkUrl" target="@linkTarget">@(item.Value<string>("caption"))</a></li>
                    if (!item.Equals(relatedLinks.Last))
                    {
                        <li>|</li>
                    }
                }
            }
        </ul>
    }
}
