.net - How to serialize an Exception object in C#?

Question

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.

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

[Serializable()]
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) { }
}
