Remarks

Aggregates most logging patterns to a single method.

Methods

BeginScope<TState>(TState)

Begins a logical operation scope.

IDisposable BeginScope<TState>(TState state)

Parameters

state TState

The identifier for the scope.

Returns

IDisposable

An IDisposable that ends the logical operation scope on dispose.

Type Parameters

TState

IsEnabled(LogLevel)

Checks if the given logLevel is enabled.

bool IsEnabled(LogLevel logLevel)

Parameters

logLevel LogLevel

level to be checked.

Returns

bool

true if enabled.

Log<TState>(LogLevel, EventId, TState, Exception, Func<TState, Exception, string>)

Writes a log entry.

void Log<TState>(LogLevel logLevel, EventId eventId, TState state, Exception exception, Func<TState, Exception, string> formatter)

Parameters

logLevel LogLevel

Entry will be written on this level.

eventId EventId

Id of the event.

state TState

The entry to be written. Can be also an object.

exception Exception

The exception related to this entry.

formatter Func<TState, Exception, string>

Function to create a string message of the state and exception.

Type Parameters
