使用json.net反序列化对象列表

我有这堂课

public class Image
{
    public string url { get; set; }
    public string url_40px { get; set; }
    public string url_50px { get; set; }
}

public class Category
{
    public List<int> ancestor_ids { get; set; }
    public int parent_id { get; set; }
    public List<object> children_ids { get; set; }
    public string nodename { get; set; }
    public int num_parts { get; set; }
    public List<Image> images { get; set; }
    public string __class__ { get; set; }
    public int id { get; set; }
}

我像这样反序列化

retObject = JsonConvert.DeserializeObject(Of Category)(jsonResp)

但是对于返回的类别列表，我如何转换为List<Category>? 谢谢

but for a list of category returned, how do i convert to List<Category>? thanks
