Hello,

I have written a custom exception object. The reason for this is I want to track additional information when an error occurs. My CLR object is defined as follows:

public class MyException : Exception
{
  public override string StackTrace
  {
    get { return base.StackTrace; }
  }
  private readonly string stackTrace;

  public override string Message
  {
    get { return base.Message; }
  }
  private readonly string message;

  public string Element
  {
    get { return element; }
  }
  private readonly string element;

  public string ErrorType
  {
    get { return errorType; }
  }
  private readonly string errorType;

  public string Misc
  {
    get { return misc; }
  }
  private readonly string misc;

  #endregion Properties

  #region Constructors

  public MyException() 
  {}

  public MyException(string message) : base(message)
  { }

  public MyException(string message, Exception inner) : base(message, inner)
  { }

  public MyException(string message, string stackTrace) : base()
  {
    this.message = message;
    this.stackTrace = stackTrace;
  }

  public MyException(string message, string stackTrace, string element, string errorType, string misc) : base()
  {
    this.message = message;
    this.stackTrace = stackTrace;
    this.element = element;
    this.errorType = errorType;
    this.misc = misc;
  }   

  protected MyException(SerializationInfo info, StreamingContext context) : base(info, context)
  {
    element = info.GetString("element");
    errorType = info.GetString("errorType");
    misc = info.GetString("misc");
  }

  public override void GetObjectData(SerializationInfo info, StreamingContext context)
  {
    base.GetObjectData(info, context);
    info.AddValue("element", element);
    info.AddValue("errorType", errorType);
    info.AddValue("misc", misc);
  }
}

I have created a copy of this custom xception in a WP7 application. The only difference is, I do not have the GetObjectData method defined or the constructor with SerializationInfo defined. If I run the application as is, I receive an error that says:

Type 'My.MyException' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute.

If I add the DataContract / DataMember attributes to the class and its appropriate members on the server-side, I receive an error that says: Type cannot be ISerializable and have DataContractAttribute attribute.

How do I serialize MyException so that I can pass an instance of it to my WCF service. Please note, I want to use my service from an Android app. Because of this, I don't want to do anything too Microsoft centric. That was my fear with DataContract / DataMember stuff.

Thank you so much for your help!
