How to deserialize object derived from Exception class using Json.net?
Adding upon already provided nice answers;
If the exception is coming from a java based application, then above codes will fail.
For this, sth. like below may be done in the constructor;
public Error(SerializationInfo info, StreamingContext context)
{
if (info != null)
{
try
{
this.ErrorMessage = info.GetString("ErrorMessage");
}
catch (Exception e)
{
**this.ErrorMessage = info.GetString("message");**
}
}
}
Adding a new constructor
public Error(SerializationInfo info, StreamingContext context){}
solved my problem.
Here complete code:
[Serializable]
public class Error : Exception
{
public string ErrorMessage { get; set; }
public Error(SerializationInfo info, StreamingContext context)
{
if (info != null)
this.ErrorMessage = info.GetString("ErrorMessage");
}
public override void GetObjectData(SerializationInfo info,StreamingContext context)
{
base.GetObjectData(info, context);
if (info != null)
info.AddValue("ErrorMessage", this.ErrorMessage);
}
}
Alternatively, you can choose the OptIn strategy and define the properties that should be processed. In case of your example:
[JsonObject(MemberSerialization.OptIn)]
public class Error : Exception, ISerializable
{
[JsonProperty(PropertyName = "error")]
public string ErrorMessage { get; set; }
[JsonConstructor]
public Error() { }
}
