c# - 尝试从 URL 反序列化 .NET 的 JSON，但出现错误

Question

我正在尝试使用以下代码反序列化 URL:

     private void RefeshList_Click(object sender, EventArgs e)
        {
            WebClient list = new WebClient();
            string text = list.DownloadString("http://www.classicube.net/api/serverlist/");
            var server = JsonConvert.DeserializeObject<RootObject>(text);
             serverlist.Text = text;

            }
        }
    }

public class RootObject
{
    public string hash { get; set; }
    public string ip { get; set; }
    public int maxplayers { get; set; }
    public string mppass { get; set; }
    public string name { get; set; }
    public int players { get; set; }
    public int port { get; set; }
    public int uptime { get; set; }

}

但我得到一个错误:

An unhandled exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in Newtonsoft.Json.dll

Additional information: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'RootObject' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.

To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.

这是一个json数组。使用

var server = JsonConvert.DeserializeObject<List<RootObject>>(text);
