我正在上课只有私人领域和他们的公共吸气者。我需要将类对象转换为JSON String,因此我使用的是JSON.Net。
以下是将类对象转换为JSON字符串的简单代码段。
MyClass obj = new MyClass();
string json = JsonConvert.SerializeObject(obj);
Console.WriteLine(json);
但方法SerializeObject
会在StackOverflowException
类MyClass
的字段中抛出DateTime
。这里发生了什么?
更新
以下是MyClass
的样子(因为它,我不介意分享实际的课程)
class MyClass
{
private int _Model;
public int Model
{
get
{
return _Model;
}
set
{
_Model = value;
}
}
private long _ProductionControlNumber;
public long ProductionControlNumber
{
get
{
return _ProductionControlNumber;
}
set
{
_ProductionControlNumber = value;
}
}
private DateTime _ProductionDate;
public DateTime ProductionDate
{
get
{
return _ProductionDate;
}
set
{
_ProductionDate = value;
}
}
private DateTime _TestDate;
public DateTime TestDate
{
get
{
return _TestDate;
}
set
{
_TestDate = value;
}
}
private DateTime _TestStartTime;
public DateTime TestStartTime
{
get
{
return _TestStartTime;
}
set
{
_TestStartTime = value;
}
}
private TimeSpan _TestDuration;
public TimeSpan TestDuration
{
get
{
return _TestDuration;
}
set
{
_TestDuration = value;
}
}
public DateTime TestEndTime
{
get
{
//TODO Perform start end time computing logic.
return TestEndTime;
}
}
private int _TestBed;
public int TestBed
{
get
{
return _TestBed;
}
set
{
_TestBed = value;
}
}
private long _EngineSerial;
public long EngineSerial
{
get
{
return _EngineSerial;
}
set
{
_EngineSerial = value;
}
}
private Single _FuelSpecificGravity;
public Single FuelSpecificGravity
{
get
{
return _FuelSpecificGravity;
}
set
{
_FuelSpecificGravity = value;
}
}
private long _FuelConsume100;
public long FuelConsume100
{
get
{
return _FuelConsume100;
}
set
{
_FuelConsume100 = value;
}
}
private long _FuelConsume110;
public long FuelConsume110
{
get
{
return _FuelConsume100;
}
set
{
_FuelConsume100 = value;
}
}
private int _TemporaryRPM;
public int TemporaryRPM
{
get
{
return _TemporaryRPM;
}
set
{
_TemporaryRPM = value;
}
}
private int _PermanentRPM;
public int PermanentRPM
{
get
{
return _PermanentRPM;
}
set
{
_PermanentRPM = value;
}
}
private Single _RatedPower;
public Single RatedPower
{
get
{
return _RatedPower;
}
set
{
_RatedPower = value;
}
}
private int _RatedSpeed;
public int RatedSpeed
{
get
{
return _RatedSpeed;
}
set
{
_RatedSpeed = value;
}
}
private double _PulleyDiameter;
public double PulleyDiameter
{
get
{
return _PulleyDiameter;
}
set
{
_PulleyDiameter = value;
}
}
private double _RopeDiameter;
public double RopeDiameter
{
get
{
return _RopeDiameter;
}
set
{
_RopeDiameter = value;
}
}
private Single _FullLoad;
public Single FullLoad
{
get
{
return _FullLoad;
}
set
{
_FullLoad = value;
}
}
}
另外,我将有另一个类,它将具有MyClass
类型字段(以及它自己的类似字段集),它也将被转换为JSON字符串,而且不应该是因为据说JSON.Net也支持这种情况。
注意:我是C#的新手,但我以前曾在Java中使用JSON,在那里我可以使用JSONObject
和JSONArray
进行游戏,他们是很直接。
答案 0 :(得分:3)
看起来你的TestEndTime属性的getter引用了它自己。因此,当Json.NET尝试序列化它时,它会递归访问自身并导致StackOverflowException。
希望有所帮助!
