Question

我有一个这样的数组：

{

    "HALTESTELLEN_ID": "214460106",
    "TYP": "stop",
    "DIVA": "60200001",

    },
    {

},
"214460107": {

        "STEIG_WGS84_LON": "16.4509825453734"
    }],
    "LINES": ["32A"]
},
... and so on

有没有办法在List<class>中格式化这样的内容？我试图这样做，但他总是停在21460106号码。还尝试了json2csharp，但只有5000个类，每个类都有这个数字作为名称。

您的外部JSON容器不是数组，它是JSON object：由大括号包围的逗号分隔的名称/值对集合。由于名称是任意键而不是固定的，因此将其反序列化的最简单方法是作为字典。

类型：

public class PLATFORM
{
    public string LINIE { get; set; }
    public string ECHTZEIT { get; set; }
    public string VERKEHRSMITTEL { get; set; }
    public string RBL_NUMMER { get; set; }
    public string BEREICH { get; set; }
    public string RICHTUNG { get; set; }
    public string REIHENFOLGE { get; set; }
    public string STEIG { get; set; }
    public string STEIG_WGS84_LAT { get; set; }
    public string STEIG_WGS84_LON { get; set; }
}

public class RootObject
{
    public string HALTESTELLEN_ID { get; set; }
    public string TYP { get; set; }
    public string DIVA { get; set; }
    public string NAME { get; set; }
    public string GEMEINDE { get; set; }
    public string GEMEINDE_ID { get; set; }
    public string WGS84_LAT { get; set; }
    public string WGS84_LON { get; set; }
    public string STAND { get; set; }
    public List<PLATFORM> PLATFORMS { get; set; }
    public List<string> LINES { get; set; }
}

反序列化代码：

var dict = JsonConvert.DeserializeObject<Dictionary<long, RootObject>>(json);

我选择了long作为密钥类型，因为所有的根属性名称都是整数字符串。如果没有，您可以使用Dictionary<string, RootObject>。

为了生成RootObject类，我将JSON从根对象中的值的一个复制 - 在这种情况下为"214460106"的值 - 到{{ 3}}

我不相信可以使用数字作为字段，尝试以字母字符开头，例如A214460106。

这只是测试格式正确的快速方法。您可以从列表转换为Json字符串并返回到数据表，只是为了检查字符串是否正常工作而无需使用模型。

  private void button1_Click(object sender, EventArgs e)
    {
        List<Employees> employees = new List<Employees>();
        Employees employee = new Employees();
        employee.firstName = "a";
        employees.Add(employee);

        string json = JsonConvert.SerializeObject(employees);
        DataTable dt = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));
    }



}
public class Employees
{
    public string firstName { get; set; }
    public string lastName { get; set; }

}
