Ninject，如何注入通用的Logger T?通过调用LoggerFactory.CreateLogger [英] Ninject, how inject a generic Logger<T> by calling LoggerFactory.CreateLogger

问题描述

我正在研究ASP.NET MVC应用程序.

I am working on an ASP.NET MVC application.

我已经在从Global.asax调用的静态类中初始化了LoggerFactory

I have initialized my LoggerFactory in a static class which is called from Global.asax

using Microsoft.Extensions.Logging;
using Serilog;
using System.IO;

namespace web
{
    public static class LogConfig
    {
        public static LoggerFactory LoggerFactory = new LoggerFactory();

        public static void RegisterLogger()
        {
            LoggerFactory = new LoggerFactory();
            Log.Logger = new LoggerConfiguration().MinimumLevel.Debug().WriteTo.RollingFile(Path.Combine("", "log-{Date}.txt")).CreateLogger();
            LoggerFactory.AddSerilog();
        }
    }
}

现在我要使用ninject将ILogger的实例注入到我的构造函数中...

now I want to use ninject, to inject an instance of ILogger into my constructor...

在我的构造函数中，我有:

In my constructor I have:

private ILogger<MyTypeController> _logger;

public MyTypeController(ILogger<MyTypeController>) 
{
    // This works fine but I want to inject it
    _logger = LogConfig.LoggerFactory.CreateLogger<MyTypeController>();
}

上面的代码有效，但是我想使用ninject注入它.这是我尝试过的方法，但甚至没有编译:

The above code works, but I want to inject it using ninject... this is what I have tried but does not even compile:

kernel.Bind(typeof(ILogger<>)).ToProvider(LogConfig.LoggerFactory.CreateLogger<>());

推荐答案

我正在使用NLog进行以下操作，但它也可能与Ninject一起使用:

I'm doing the following with NLog but it is also likely to work with Ninject:

var createLoggerMethod =
    typeof(LoggerFactoryExtensions).GetMethod(nameof(LoggerFactoryExtensions.CreateLogger),
        new[] {typeof(ILoggerFactory)});
kernel.Bind(typeof(ILogger<>)).ToMethod(context =>
{
    var createLoggerGeneric = createLoggerMethod.MakeGenericMethod(context.GenericArguments);
    var logger = createLoggerGeneric.Invoke(null, new []{ loggerFactory });
    return logger;
});
