Question

我想解析我的json文件。但是，当我从现有的api获取我的json时，我发现了一个问题，我想创建一个函数来解析我的json并存储在列表中

   IRestResponse response = ctm(departTime, departure, arrival);
        JObject resultJSon = JObject.Parse(response.Content);
        Console.WriteLine("Rows:" + resultJSon);
        JArray rows = (JArray)(resultJSon["rows"]);
        if (rows == null) return ret;
        Console.WriteLine("Rows:" + rows);
        foreach (var r in rows)
        {
            Console.WriteLine(r);
            JArray cells = (JArray)r["cell"];
            Voyage voyage = new Voyage();
            voyage.Arrival = new Ville();
            voyage.Arrival.Name = arrival;
            voyage.Depart = new Ville(0, departure);
            voyage.Company = new Company();
            voyage.Company.Name = "CTM";
            for (var i = 2; i < cells.Count; i++)
            {
                string tmp = (string)cells[i];
                if (i == 2)
                {
                    voyage.DepartTime = 
     DateTime.Parse(date.ToString("yyyy/MM/dd") + " " + tmp.Split(" 
      ".ToCharArray())[0]);
                }
                else
                if (i == 3)
                {
                    //price
                    voyage.Price = Double.Parse(tmp);
                }
                else if (i == 4)
                {
                    voyage.Type = tmp;
                    if (tmp == null || tmp.Equals(""))
                    {
                        voyage.Type = "CONFORT";
                    }

                }
                else if (i == 5)
                {
                    string[] els = tmp.Split(" ".ToCharArray());
                    if (els.Length >= 2)
                    {
                        if (els[els.Length - 1].Equals("Lendemain"))
                        {
                            DateTime tmpD = new DateTime(date.Year, 
  date.Month, date.Day);
                            tmpD = tmpD.AddDays(1);
                            voyage.ArrivalTime = 
   DateTime.Parse(tmpD.ToString("yyyy/MM/dd") + " " + els[0]);
                        }
                        else
                        {
                            voyage.ArrivalTime = 
  DateTime.Parse(date.ToString("yyyy/MM/dd") + " " + els[0]);
                        }
                    }
                }
            }
            ret.Add(voyage);
        }

我的json文件如下：

我的上班时间是航程，这是课程：

   public class Voyage
{

    public Voyage()
    {
    }
    public Ville Arrival { get; set; }
    public Ville Depart { get; set; }
    public Company Company { get; set; }
    public string Type { get; set; }
    public double Price { get; set; }
    public DateTime ArrivalTime { get; set; }
    public DateTime DepartTime { get; set; }
 }

请帮助我找出问题出在哪里

我的问题已解决。问题在这里：

   voyage.Price=Double.Parse(tmp);

我无法解析我的字符串。这是怎么做的：

  voyage.Price = double.Parse(tmp, CultureInfo.InvariantCulture);

我强烈建议使用Newtonsoft进行JSON序列化和反序列化（可以在NuGet包中找到）。使用Newtonsoft，您可以序列化为强类型的对象，反之亦然。在这种情况下，您的代码将看起来像这样：

var responseObj = Newtonsoft.Json.JsonConvert.DeserializeObject<Voyage>(response.Content);

responseObj将包含所有反序列化的信息，而“行”对象将在“单元格”属性中包含更详细的信息。

对于Voyage，班级看起来像这样

public class Row
{
    public string id { get; set; }
    public List<string> cell { get; set; }
}

public class Voyage
{
    public string page { get; set; }
    public int total { get; set; }
    public string records { get; set; }
    public List<Row> rows { get; set; }
}
