Dynamically show button in a foreach loop

I have two buttons in my foreach loop. I need both to appear unless it is the first item in the loop or the last item in the loop.

@foreach (var item in @Model.IPACS_Processes.IPACS_Procedures)
{
    <li class="span6">
        <img src="../../Images/thumbs/doc.png" alt="" class="pull-left" />
        <div class="comment-info">
            <h4>
                <a href="@Url.Action("ViewProcedure", new { id = item.procedureID })" data-original-title="@item.name">
                    @item.name</a></h4>
            <h5>
                <small>Owner: </small> <a href="javascript:void(0);">@item.owner</a></h5>
                <br />
            <p>
            @item.description
            </p>
            <br />
            <p>
                <a href="" class="btn btn-small"><span class="iconfa-double-angle-up icon-white">
                </span>Move Up</a>

                <a href="" class="btn btn-small"><span class="iconfa-double-angle-down"></span>
                    Move Down</a>
            </p>
        </div>
    </li>
    <br style="clear: both;" />
}

I need the "Move Up" button visible unless it is the first item in the loop, then I need the "Move Down" button visible unless it is the last item in the loop.

I'm not sure if setting up a count iterator is my only option, or if there is a cleaner way?

You can simply set an index and compare it against the upper and lower bounds of your array, or use the Count property of the array.

Something like this.

@{
  int i = 0;

  foreach (var item in Model.IPACS_Processes.IPACS_Procedures)
  {
    <!-- stuff and stuff --!>

    if(i > 0) {
            <a href="" class="btn btn-small"><span class="iconfa-double-angle-up icon-    white">
            </span>Move Up</a>
    }

    if(i < Model.IPACS_Processes.IPACS_Procedures.Count)
    {
            <a href="" class="btn btn-small"><span class="iconfa-double-angle-down">     </span>
                Move Down</a>
    }

    i++;

  }
}
