Obtener un log del SQL generado por un DataContext

gistfile1.cs

        private TRet WithLogging<T, TRet>(T context, string logmsg, Func<T, TRet> func) where T : DataContext
        {
            TRet result;

            var log = context.Log;
            var builder = new StringBuilder();
            try
            {
                context.Log = new StringWriter(builder);

                result = func.Invoke(context);
            }
            finally
            {
                Log.InfoFormat("{0}:\n{1}", logmsg, builder);
                context.Log = log;
            }

            return result;
        }

Quizá parezca demasiada vuelta pero.. que tal esto :) https://gist.github.com/3147119
