c# Reflection Generic List Count

Is there a cleaner way to get a list count using reflection then this?

 Boolean include = false;

 foreach (PropertyInfo item in props)
        {
            var pt = item.PropertyType;                

            String listType = pt.GetGenericArguments()[0].Name;

             // Is there a better solution than this?
             switch (listType)
                            {
                                case "jsonResult":
                                    var list = v as List<jsonResult>;

                                    include =  list.count > 0;
                                    break;                                
                            }
        }
    )

I've tried a variety of ideas from Googling but haven't had any luck.
