.NET Nlogを使用してログ情報を記録する(三)

using NLog; 

using NLog.Targets; 

using NLog.Config; 

using NLog.Win32.Targets; 

class Example 

{ 

    static void Main(string[] args) 

    { 

        // Step 1. Create configuration object 

        LoggingConfiguration config = new LoggingConfiguration(); 

        // Step 2. Create targets and add them to the configuration 

        ColoredConsoleTarget consoleTarget = new ColoredConsoleTarget(); 

        config.AddTarget("console", consoleTarget); 

        FileTarget fileTarget = new FileTarget(); 

        config.AddTarget("file", fileTarget); 

        // Step 3. Set target properties 

        consoleTarget.Layout = "${date:format=HH\\:MM\\:ss} ${logger} ${message}"; 

        fileTarget.FileName = "${basedir}/file.txt"; 

        fileTarget.Layout = "${message}"; 

        // Step 4. Define rules 

        LoggingRule rule1 = new LoggingRule("*", LogLevel.Debug, consoleTarget); 

        config.LoggingRules.Add(rule1); 

        LoggingRule rule2 = new LoggingRule("*", LogLevel.Debug, fileTarget); 

        config.LoggingRules.Add(rule2); 

        // Step 5. Activate the configuration 

        LogManager.Configuration = config; 

        // Example usage 

        Logger logger = LogManager.GetLogger("Example"); 

        logger.Trace("trace log message");
