Newtonsoft.JSON的JSON C#反序列化对象错误

我有一个JSON字符串，它是从BaseCamp API获得的。我知道JSON是有效的，但是，我不能使用Newtonsoft.JSON.来反序列化对象

我得到一个错误说：

Cannot deserialize the current JSON array (e.g.[1,2,3]) into type BaseCamp.Code.Projects+RootObject because the type requires a JSON objet (e.g. {"name":"value"}) to deserialize correctly.

JSON（从API返回的未格式化内容减去URL的值）

我的C#类：

public class Projects  
    {  
        public class RootObject  
        {  
            public int id { get; set; }  
            public string name { get; set; }  
            public string description { get; set; }  
            public bool archived { get; set; }  
            public bool is_client_project { get; set; }  
            public string created_at { get; set; }  
            public string updated_at { get; set; }  
            public bool trashed { get; set; }  
            public string color { get; set; }  
            public bool draft { get; set; }  
            public bool template { get; set; }  
            public string last_event_at { get; set; }  
            public bool starred { get; set; }  
            public string url { get; set; }  
            public string app_url { get; set; }  
        }  
    }    

我假设我的类的设置方式有问题，但我看不出来。

var json = JsonConvert.DeserializeObject<Projects.RootObject[]>(response); 

var json = JsonConvert.DeserializeObject<List<Projects.RootObject>>(response);
