using System;

class LogTableOverflowException : Exception
{
    const string overflowMessage = "The log table has overflowed.";

    public LogTableOverflowException( 
        string auxMessage, Exception inner ) :
            base( String.Format( "{0} - {1}", 
                overflowMessage, auxMessage ), inner )
    {
        this.HelpLink = "http://msdn.microsoft.com";
        this.Source = "Exception_Class_Samples";
    }
}
class OverflowDemo 
{
    public static void Main() 
    {
        try{
            throw new LogTableOverflowException( 
                String.Format( "Record \"{0}\" was not logged.", 
                    "asdf" ), null );
        }catch( Exception ex ){
            Console.WriteLine( "\nSource ---\n{0}", ex.Source );

        }
