How do I extract the inner exception from a soap exception in ASP.NET?

Question

I have a simple web service operation like this one:

    [WebMethod]
    public string HelloWorld()
    {
        throw new Exception(\"HelloWorldException\"

It IS possible!

Service operation example:

try
{
   // do something good for humanity
}
catch (Exception e)
{
   throw new SoapException(e.InnerException.Message,
                           SoapException.ServerFaultCode);
}

Client consuming the service:

try
{
   // save humanity
}
catch (Exception e)
{
   Console.WriteLine(e.Message);    
}

Just one thing - you need to set customErrors mode='RemoteOnly' or 'On' in your web.config (of the service project).
