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:
- 创建一个LoggingConfiguration对象,用来保存配置信息
- 至少创建一个输出目标对象
- 设置该输出目标对象的属性
- 设置LoggingRule对象,并将其添加到LoggingConfiguration对象的LoggingRules集合中
- 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");
}
}
