Common.Logging.Core The type of method that is passed into e.g. and allows the callback method to "submit" it's message to the underlying output system. the format argument as in the argument list as in Erich Eichinger Interface for basic operations to read .NET application configuration information. Provides a simple abstraction to handle BCL API differences between .NET 1.x and 2.0. Also useful for testing scenarios. Mark Pollack Parses the configuration section and returns the resulting object.

Primary purpose of this method is to allow us to parse and load configuration sections using the same API regardless of the .NET framework version.

See also System.Configuration.ConfigurationManager Name of the configuration section. Object created by a corresponding IConfigurationSectionHandler. A simple logging interface abstracting logging APIs. Implementations should defer calling a message's until the message really needs to be logged to avoid performance penalties. Each log method offers to pass in a instead of the actual message. Using this style has the advantage to defer possibly expensive message argument evaluation and formatting (and formatting arguments!) until the message gets actually logged. If the message is not logged at all (e.g. due to settings), you won't have to pay the peformance penalty of creating the message. The example below demonstrates using callback style for creating the message, where the call to the and the underlying only happens, if level is enabled: Log.Debug( m=>m("result is {0}", random.NextDouble()) ); Log.Debug(delegate(m) { m("result is {0}", random.NextDouble()); }); Mark Pollack Bruno Baia Erich Eichinger Log a message object with the level.

LoggerFactoryAdapter interface is used internally by LogManager Only developers wishing to write new Common.Logging adapters need to worry about this interface.

The key of the logger Interface for LogManager The key of the default configuration section to read settings from. You can always change the source of your configuration settings by setting another instance on . Reset the infrastructure to its default settings. This means, that configuration settings will be re-read from section <common/logging> of your app.config. This is mainly used for unit testing, you wouldn't normally use this in your applications.
Note: instances already handed out from this LogManager are not(!) affected. Resetting LogManager only affects new instances being handed out. Reset the infrastructure to its default settings. This means, that configuration settings will be re-read from section <common/logging> of your app.config. This is mainly used for unit testing, you wouldn't normally use this in your applications.

Primarily used for testing purposes but maybe useful to obtain configuration information from some place other than the .NET application configuration file. The configuration reader. Gets or sets the adapter. The adapter. Gets the logger by calling on the currently configured using the type of the calling class. This method needs to inspect the StackTrace in order to determine the calling class. This of course comes with a performance penalty, thus you shouldn't call it too often in your application. the logger instance obtained from the current Gets the logger by calling on the currently configured using the specified type. the logger instance obtained from the current Gets the logger by calling on the currently configured using the specified type.
