我正在尝试解析一个JSON字符串，其中包含多个结果。我正在从我们的帮助台票务系统调用一个API。我可以从API获取我想要的所有票务信息，但我无法将其解析为单个字符串。
这就是我目前使用JSON Newtonsoft所做的。

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

字符串
tickets是JSON字符串。它有正确的数据，但当我试图输出其中一个值时，

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

型
它不工作，显示0或null值。我可以让它在另一个JSON结果中工作，但它只有一个结果。
下面是我的类定义存储在这个JSON中的数据：

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; }
}

型
下面是由API返回的JSON示例：

您需要创建这样的对象来MapJSON内容

public class Root
{
    public List<Data> data { get; set; }
    public Metadata metadata { get; set; }
}

 public class Metadata
{
    public List<string> columns { get; set; }
    public List<SortBy> sortBy { get; set; }
    public Dictionary<string, object> attributes { get; set; }
    public object filters { get; set; }
    public int? lastCursorId { get; set; }
    public List<string> allColumns { get; set; }
    public List<string> columnNamesForExporting { get; set; }
    public List<string> allRequiredColumns { get; set; }
}

public class Data
{
    public string assignedAppUser { get; set; }
    public double createTime { get; set; }
    public string description { get; set; }
    public int id { get; set; }
    public string priority { get; set; }
    public string requester { get; set; }
    public string severity { get; set; }
    public double? solvedTime { get; set; }
    public string source { get; set; }
    public Status status { get; set; }
    public string summary { get; set; }
    public List<string> tags { get; set; }
    public string ticketForm { get; set; }
    public object triggeredCondition { get; set; }
    public string type { get; set; }
}

public class SortBy
{
    public string field { get; set; }
    public string direction { get; set; }
}

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

字符串
然后“data”是对象的一个元素，所以你可以像这样访问它
你可以像这样得到或从下面的文件中得到

var ticketData = JsonConvert.DeserializeObject<Root>("replace json here");

型
Expanded results

var ticketData = JsonConvert.DeserializeObject<Root>(File.ReadAllText("replace json file here"));
var firstSummary = ticketData.data[0].summary;
Console.WriteLine(firstSummary);

型
将您的Json输入替换为此处的文件

您的列表位于'data'中，因此在转换之前需要将其与json字符串分离。您可以尝试：

JObject o = JObject.Parse(tickets);
var ticketData = JsonConvert.DeserializeObject <TicketData> (o["data"]);
Console.WriteLine(ticketData.summary.ToString());

字符串

您正在处理的JSON结构有一个名为“data”的根元素，其中包含一个ticket信息数组。您的TicketData类用一个Data对象列表反映了这个结构。因此，您应该相应地将其转换。
您的验证代码应该如下所示：

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

字符串
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据的属性。
