如何用编程的方法来配置Logging Application Block

const string Template = "Timestamp: {timestamp}{newline}" +
                    "Message: {message}{newline}" +
                    "Category: {category}{newline}" +
                    "Machine: {machine}{newline}";
TextFormatter formatter = new TextFormatter(Template);

const string LogFilePath = @"d:\\share\\messages.log";
FlatFileTraceListener logFileListener =
            new FlatFileTraceListener(LogFilePath,
                                       "----------",
                                       "----------",
                                       formatter);

LogSource mainLogSource = new LogSource("MainLogSource", SourceLevels.All);

mainLogSource.Listeners.Add(logFileListener);
