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：

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");
}
}
