Working Experience - NLog 多实例时配置文件冲突

正文

问题: 当前项目已使用 NLog 的情况下再引用使用 NLog 的项目, 出现配置文件冲突, 有一个配置文件不工作

方法: 使用 LogFactory 代替 LogManager 来获取 Logger 实例

internal class MyLogManager
{
    // A Logger dispenser for the current assembly (Remember to call Flush on application exit)
    public static LogFactory Instance { get { return _instance.Value; } }
    private static Lazy<LogFactory> _instance = new Lazy<LogFactory>(BuildLogFactory);

    //
    // Use a config file located next to our current assembly dll
    // eg, if the running assembly is c:\path\to\MyComponent.dll
    // the config filepath will be c:\path\to\MyComponent.nlog
    //
    // WARNING: This will not be appropriate for assemblies in the GAC
    //
    private static LogFactory BuildLogFactory()
    {
         // Use name of current assembly to construct NLog config filename
         Assembly thisAssembly = Assembly.GetExecutingAssembly();
         string configFilePath = Path.ChangeExtension(thisAssembly.Location, ".nlog"); 

         LogFactory logFactory = new LogFactory();
         logFactory.Configuration = new XmlLoggingConfiguration(configFilePath, true, logFactory);
         return logFactory;
    }
}

// 使用下面两个方法中的一个获取 Logger 实例
Logger logger = MyLogManager.Instance.GetCurrentClassLogger();
Logger logger = MyLogManager.Instance.GetLogger("name");
