C# 解析具有多个结果的 JSON 字符串

Question

我正在尝试解析具有多个结果的 JSON 字符串。我正在从我们的服务台票务系统调用 API。我能够从 API 中获取所有我想要的票务信息到 var 中，但我无法将其解析为单独的字符串。

这就是我目前正在使用 JSON Newtonsoft 所做的事情。

var ticketData = JsonConvert.DeserializeObject <TicketData> (tickets);

tickets

是 JSON 字符串。它包含正确的数据，但是当我尝试输出其中一个值时

Console.WriteLine(ticketData.summary.ToString());

它不起作用并显示 0 或空值。我可以让它在另一个 JSON 结果中工作，但它只有一个结果。

以下是我的类，定义了此 JSON 中存储的数据：

public class TicketData
{
    public List<Data> datas { get; set; }
}

public class Data
{
    public string assignedAppUser { get; set; }
    public decimal createTime { get; set; }
    public string description { get; set; }
    public int id { get; set; }
    public string priority { get; set; }
    public string requestor { get; set; }
    public string severity { get; set; }
    public decimal solvedTime { get; set; }
    public string source { get; set; }
    public List<Status> statuses { get; set; }
    public string summary { get; set; }
    public string tags { get; set; }
    public string ticketForm { get; set; }
    public string triggeredCondition { get; set; }
    public string type { get; set; }
}

public class Status
{
    public int statusID { get; set; }
    public string displayName { get; set; }
    public int parentID { get; set; }
}

以下是 API 返回的 JSON 示例：

您正在处理的 JSON 结构有一个名为“data”的根元素，其中包含票证信息数组。您的 TicketData 类通过数据对象列表反映了此结构。因此，您应该相应地反序列化它。

您的反序列化代码应如下所示：

var ticketData = JsonConvert.DeserializeObject<TicketData>(tickets);
    
    foreach (var ticket in ticketData.datas)
    {
        Console.WriteLine(ticket.summary);
        // Access other properties as needed
    }

请注意，datas 是 TicketData 类中的属性名称，对应于 JSON 中的“data”数组。迭代此列表以访问每个票证的属性。
