Newtonsoft.Json反序列化后为空对象

Question

我正在尝试使用以下代码从URL反序列化JSON。 即使下载有效的JSON字符串，我也得到一个空对象。

public static void tryjson() {
    string json = new WebClient().DownloadString("http://www.sofascore.com/football/livescore/json");
    SportItem sportItem = JsonConvert.DeserializeObject<SportItem>(json);
}

    public bool isShortDate { get; set; }
}

我究竟做错了什么？

Answer 1

尝试这个：

System.Net.WebClient wc = new System.Net.WebClient();
wc.DownloadStringCompleted += (s, u) =>
{
    DownloadStringCompleted(s, u);
};
wc.DownloadStringAsync(new Uri("http://www.sofascore.com/football/livescore/json"));


private void DownloadStringCompleted(object s, DownloadStringCompletedEventArgs u)
{
    try
    {
        var Item = JsonConvert.DeserializeObject<RootObject>(u.Result.ToString());
    }
    catch (Exception ex)
    { }
}

看来您需要首先解析json对象。 例：-

var data = (JObject)JsonConvert.DeserializeObject(resultJson);
