How to serialize an Exception object in C#?


I am trying to serialize an Exception object in C#. However, it appears that it is impossible since the Exception class is not marked as [Serializable]. Is there a way to work around that?

If something goes wrong during the execution of the application, I want to be informed with the exception that occurred.

My first reflex is to serialize it.

What I've done before is create a custom Error class. This encapsulates all the relevant information about an Exception and is XML serializable.

public class Error
    public DateTime TimeStamp { get; set; }
    public string Message { get; set; }
    public string StackTrace { get; set; }

    public Error()
        this.TimeStamp = DateTime.Now;

    public Error(string Message) : this()
        this.Message = Message;

    public Error(System.Exception ex) : this(ex.Message)
        this.StackTrace = ex.StackTrace;

    public override string ToString()
        return this.Message + this.StackTrace;

Create a custom Exception class with the [Serializable()] attribute. Here's an example taken from the MSDN:

public class InvalidDepartmentException : System.Exception
    public InvalidDepartmentException() { }
    public InvalidDepartmentException(string message) : base(message) { }
    public InvalidDepartmentException(string message, System.Exception inner) : base(message, inner) { }

    // Constructor needed for serialization 
    // when exception propagates from a remoting server to the client.
    protected InvalidDepartmentException(System.Runtime.Serialization.SerializationInfo info,
        System.Runtime.Serialization.StreamingContext context) : base(info, context) { }
