Namespace:

Microsoft.Extensions.Logging

Assembly:

Microsoft.Extensions.Logging.Abstractions.dll

Package:

Microsoft.Extensions.Logging.Abstractions v9.0.0

Source:

ILoggerT.cs

A generic interface for logging where the category name is derived from the specified TCategoryName type name. Generally used to enable activation of a named ILogger from dependency injection.

generic <typename TCategoryName>
public interface class ILogger : Microsoft::Extensions::Logging::ILogger

public interface ILogger<out TCategoryName> : Microsoft.Extensions.Logging.ILogger

type ILogger<'CategoryName> = interface
    interface ILogger

Public Interface ILogger(Of Out TCategoryName)
Implements ILogger

Type Parameters

TCategoryName

The type whose name is used for the logger category name.

This type parameter is covariant. That is, you can use either the type you specified or any type that is more derived. For more information about covariance and contravariance, see Covariance and Contravariance in Generics.

Derived

Microsoft.Extensions.Logging.Abstractions.NullLogger<T>

Microsoft.Extensions.Logging.Logger<T>

Microsoft.Extensions.Logging.Testing.FakeLogger<T>

Implements

ILogger

Methods
