Question

我正在尝试在Flutter（Dart）中序列化一些数据，并将其发送到我的C＃.NET服务器进行处理。问题在于，在.NET中反序列化JSON数据时，它无法将某些值识别为字符串（大多数情况下无法将所述字符串解析为布尔值）。

对于Dart我已经尝试过

dart：convert
flutterdev建议的JSON解析方法

'@JsonSerializable(explicitToJson: true)
ClassName {
...
factory ClassName.fromJson(Map<String, dynamic> json) => _$ClassNameFromJson(json);
  Map<String, dynamic> toJson() => _$ClassNameToJson(this);
}

对于C＃.NET，我已经尝试过

ClassName(SerializationInfo info, StreamingContext ctx)与映射
NewtonSoft.JsonConvert
JavascriptSerializer

这里有一些参考资料可以帮助我将疲倦的杂物拼凑在一起。

通过重新共享https://i.gyazo.com/27969594b2d5beb4fdb58a82418133a5.png细分的错误
我找到了一个解决方法，该方法是在字符串中用引号引起来，例如String str = '"PaddingFix"'
另一个解决方法是重命名字符串JSON可接受的布尔值，例如：String str = 'false'

C＃条码类别：


[Serializable()]
public class Barcode
{
    public string Raw { get; set; }
    public string HalId { get; set; }
    public string PolicyShort { get; set; }
    public string PolicyLong { get; set; }
    public bool IsClaims { get; set; }
    public int? CurrentPage { get; set; }
    public int? TotalPages { get; set; }
    public string readable = "NOTASSIGNED";


    public Barcode(String raw, String halId, String policyShort, String policyLong,
        bool isClaims, int currentPage, int totalPages)
    {
        Raw = raw;
        HalId = halId;
        PolicyShort = policyShort;
        PolicyLong = policyLong;
        IsClaims = isClaims;
        CurrentPage = currentPage;
        TotalPages = totalPages;
    }

    public void GetObjectData(SerializationInfo info, StreamingContext context)
    {
        info.AddValue("Raw", Raw);
        info.AddValue("HalId", HalId);
        info.AddValue("PolicyShort", PolicyShort);
        info.AddValue("PolicyLong", PolicyLong);
        info.AddValue("IsClaims", IsClaims);
        info.AddValue("CurrentPage", CurrentPage);
        info.AddValue("TotalPages", TotalPages);
    }

    public Barcode(SerializationInfo info, StreamingContext context)
    {
        Raw = (string)info.GetValue("Raw", typeof(string));
        HalId = (string)info.GetValue("HalId", typeof(string));
        PolicyShort = (string)info.GetValue("PolicyShort", typeof(string));
        PolicyLong = (string)info.GetValue("PolicyLong", typeof(string));
        IsClaims = (bool)info.GetValue("IsClaims", typeof(bool));
        CurrentPage = (int)info.GetValue("CurrentPage", typeof(int));
        TotalPages = (int)info.GetValue("TotalPages", typeof(int));
    }
}

最后但并非最不重要的是，我的Flutter应用程序的条形码类


@JsonSerializable(explicitToJson: true)
class Barcode {
  Barcode(this.raw, this.halId,this.policyShort,this.policyLong, this.isClaims);

  @JsonKey(name: 'Raw')
  String raw;
  @JsonKey(name: 'HalId')
  String halId;
  @JsonKey(name: 'PolicyShort')
  String policyShort;
  @JsonKey(name: 'PolicyLong')
  String policyLong;
  @JsonKey(name: 'IsClaims')
  bool isClaims;
  @JsonKey(name: 'CurrentPage')
  int currentPage;
  @JsonKey(name: 'TotalPages')
  int totalPages;

  String readable = 'NOTASSIGNED';

  factory Barcode.fromJson(Map<String, dynamic> json) => _$BarcodeFromJson(json);
  Map<String, dynamic> toJson() => _$BarcodeToJson(this);

  /*
  Barcode.fromJson(Map<String, dynamic> json)
   : raw = json['Raw'],
    halId = json['HalId'],
    policyShort = json['PolicyShort'],
    policyLong = json['PolicyLong'],
    isClaims = json['IsClaims'],
    currentPage = json['CurrentPage'],
    totalPages = json['TotalPages'];

  Map<String, dynamic> toJson() => {
    'Raw' : raw,
    'HalId' : halId,
    'PolicyShort': policyShort,
    'PolicyLong': policyLong,
    'IsClaims':isClaims,
    'CurrentPage':currentPage,
    'TotalPages':totalPages
  };*/
}

TL; DR：我有一个Flutter类，带有一个List<2ndCustomClass>。由于某种原因，在通过C＃返回2ndCustomClass之后，我在解析df.loc[~df['Box'].str.contains(r'_{2}')]时遇到了问题。我相信这是由于字符串没有包含在引号中，但无法想到一个优雅的解决方案，也看不到我的问题所在。

在Dart中序列化的JSON值不会反序列化
