    if (index > 0)
    {
        var propPath = path.Substring(0, index);
        path = path.Substring(index + 1);
        o = GetValue(o, propPath);
    }

    if (o == null)
        return null;

    var property = o.GetType().GetProperty(path);

    var value = property.GetValue(o, null);

    return value;
