JSON.net 反序列化

3

我有一个JSON编码的字符串，同时我也有一个C#类：

class Pupu{
    public static List<Pupu> plist = new List<Pupu>();
    public string user {get; set;}
    public string number {get; set;}
}


[{"user":"27FFBADD7284E5CB98EAC45559589E28FDDDC3AD","number":"62827"},{"user":"27FFBADD7284E5CB98EAC45559589E28FDDDC3AD","number":"30460"}, {"user":"0D27D44D40C5185423078B3C93B3E6B596AD21A0","number":"25143"}, {"user":"0D27D44D40C5185423078B3C93B3E6B596AD21A0","number":"22776"}, {"user":"27FFBADD7284E5CB98EAC45559589E28FDDDC3AD","number":"19755"}]

我正在使用以下代码进行反序列化：

 plist = JsonConvert.DeserializeObject<List<Pupu>>(stringAbove);

我一直在收到以下信息：

 Attempt to access the method failed: System.Collections.Generic.List`1..ctor();

谢谢，我已经找了几个小时了（我对C#还很陌生）。

让我们尝试清理一下你的代码：

public class Score
{
    public string user { get; set; }
    public string number { get; set; }
}

现在你可以将JSON反序列化为得分列表：

List<Score> plist = JsonConvert.DeserializeObject<List<Score>>(stringAbove);

以下是完整示例：

public class Score
{
    public string user { get; set; }
    public string number { get; set; }
}

class Program
{
    static void Main()
    {
        var json = "[{\"user\":\"27FFBADD7284E5CB98EAC45559589E28FDDDC3AD\",\"number\":\"62827\"},{\"user\":\"27FFBADD7284E5CB98EAC45559589E28FDDDC3AD\",\"number\":\"30460\"}, {\"user\":\"0D27D44D40C5185423078B3C93B3E6B596AD21A0\",\"number\":\"25143\"}, {\"user\":\"0D27D44D40C5185423078B3C93B3E6B596AD21A0\",\"number\":\"22776\"}, {\"user\":\"27FFBADD7284E5CB98EAC45559589E28FDDDC3AD\",\"number\":\"19755\"}]";
        List<Score> plist = JsonConvert.DeserializeObject<List<Score>>(json);

        foreach (Score score in plist)
        {
            Console.WriteLine("user: {0}, number: {1}", score.user, score.number);    
        }
    }
}
