获取请求Ninject服务的类名

Question

我正在抽象NLog。到目前为止，我所拥有的。。。

public interface IAppLogger
{
    void Info(string message);
    void Warn(string message);
    void Error(string message, Exception error);
    void Fatal(string message);
     ....// other overload
}

用NLog-实现IAppLogger

public class NLogLogger : IAppLogger
{
    private readonly NLog.Logger _logger;
    public NLogLogger([CallerFilePath] string callerFilePath = "")
    {
       _logger = NLog.LogManager.GetLogger(callerFilePath);
    }
    public void Info(string message)
    {
       _logger.Info(message);
    }
    public void Warn(string message)
    {
       _logger.Warn(message);
    }
    .....// and others
 }

以及使用此服务的控制台应用程序

public class Program
{
    private static IAppLogger Log { get; set; }
    private static void Main()
    {
        var kernel = new StandardKernel();
        kernel.Load(Assembly.GetExecutingAssembly());
        Log = kernel.Get<IAppLogger>();
        Log.Info("Application Started");
        Log.Warn("Developer: Invalid date format");
        Log.Error("Divid by zero error", new DivideByZeroException());
        Console.WriteLine("nDone Logging");
        Console.ReadLine();
    }
}

以及使用Ninject的依赖项注入

public class NinjectConfig : NinjectModule
{
    public override void Load()
    {
        Bind<IAppLogger>().To<NLogLogger>()
         .WithConstructorArgument("callerFilePath", GetParentTypeName);
    }
    private static string GetParentTypeName(IContext context)
    {
        return context.Request.ParentRequest.Service.FullName;
    }
}

到目前为止还不错。但是，当我运行应用程序时，Ninject会不断为上下文返回NULL。Request.ParentRequest。我也在上下文中尝试过。Request.Target……..对于上下文，它仍然返回NULL。请求。目标。我做错了什么。请帮帮我！！！！

在这里找到了一个可能对你有用的答案，试试看：

public class NLogLogger : IAppLogger
{
    private readonly NLog.Logger _logger;
    public NLogLogger(Type callerType)
    {
       _logger = NLog.LogManager.GetLogger(callerType.Name,callerType);
    }
    public void Info(string message)
    {
       _logger.Info(message);
    }
    public void Warn(string message)
    {
       _logger.Warn(message);
    }
    .....// and others
 }
public class NinjectConfig : NinjectModule
{
    public override void Load()
    {
        Bind<IAppLogger>().ToMethod(p => new NLogLogger(p.Request.Target.Member.DeclaringType));
    }
}
