c# - Ninject 传递实现接口(interface)的构造函数参数 typeof 类

Question

我正在尝试将 Ninject 与我的应用程序日志包装器一起使用。

这是包装器:

public class NLogLogger : ILogger
{
    private readonly Logger _logger;

    public NLogLogger(Type t)
    {
        _logger = LogManager.GetLogger(t.Name);
    }
}

如您所见，我将类型传递给记录器构造函数，因此我将像下面这样使用它:

public class EntityObject
{
    public ILogger Logger { get; set; }

    public EntityObject()
    {
        Logger = new NLogLogger(typeof(EntityObject));
    }
}

现在我似乎找不到如何使用 Ninject 做类似的事情。这是我的绑定(bind)模块:

public class LoggerModule : NinjectModule
{
    public override void Load()
    {
        Bind<ILogger>().To<NLogLogger>();
    }
}

现在显然我抛出了一个异常，因为它不能将类型注入(inject)到构造函数中。我有什么想法可以做到这一点吗？

Error activating Type

No matching bindings are available, and the type is not self-bindable.

Activation path:

4) Injection of dependency Type into parameter t of constructor of type NLogLogger

3) Injection of dependency ILogger into parameter logger of constructor of type NzbGetSettingsService

2) Injection of dependency ISettingsService{NzbGetSettingsDto} into parameter nzbGetService of constructor of type DashboardController

1) Request for DashboardController

Answer 1

假设您的类如下所示:

public class EntityObject
{
    public ILogger Logger { get; set; } //it is better by the way to convert this into a private field

    public EntityObject(ILogger logger)
    {
        Logger = logger;
    }
}

您需要像这样注册您的NLogLogger:

Bind<ILogger>().To<NLogLogger>()
    .WithConstructorArgument(
        typeof(Type),
        x => x.Request.ParentContext.Plan.Type);
