foreach (SignalingHeader h in messageData.MessageData.SignalingHeaders)
{
    if ((h.Name.Equals("Supported", StringComparison.OrdinalIgnoreCase) ||
         h.Name.Equals("Required", StringComparison.OrdinalIgnoreCase)) &amp;&amp;
        "x-customfeature".Equals(h.GetValue(), StringComparison.OrdinalIgnoreCase))
