c# – JSON.net反序列化

发布时间：2020-12-16 00:03:38 所属栏目：百科来源：网络整理

导读：我有一个 JSON编码的字符串.我也有C#类： class Pupu{ public static ListPupu plist = new ListPupu(); public string user {get; set;} public string number {get; set;}}[{"user":"27FFBADD7284E5CB98EAC45559589E28FDDDC3AD","number":"62827"},{"user"

我有一个 JSON编码的字符串.我也有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"},"number":"22776"},"number":"19755"}]

我希望它：

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

我一直在：

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

谢谢,我现在正在寻找这几个小时. (我对C#很新).

解决方法

我们试着清理你的代码：

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

现在您可以将JSON反序列化为分数列表：

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

这是一个完整的例子：

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"},"number":"22776"},"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);    
        }
    }
}
