NLog类库使用探索——编程配置

    以编程的方式配置,这是我项目中的,我都不知道为什么使用编程。直接配置不很好吗,估计他也没有研究。直接上步骤和代码:

  1. 创建一个LoggingConfiguration对象,用来保存配置信息
  2. 至少创建一个输出目标对象
  3. 设置该输出目标对象的属性
  4. 设置LoggingRule对象,并将其添加到LoggingConfiguration对象的LoggingRules集合中
  5. 启用该LoggingConfiguration对象(将LogManager.Configuration设定为该LoggingConfiguration对象即可)
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");         logger.Debug("debug log message");         logger.Info("info log message");         logger.Warn("warn log message");         logger.Error("error log message");         logger.Fatal("fatal log message");     } }
