Fields

Critical()

Logs that describe an unrecoverable application or system crash, or a catastrophic failure that requires immediate attention.

Return type:Microsoft.Extensions.Logging.LogLevel 
Critical = 5
Debug()

Logs that are used for interactive investigation during development. These logs should primarily contain information useful for debugging and have no long-term value.

Return type:Microsoft.Extensions.Logging.LogLevel 
Debug = 1
Error()

Logs that highlight when the current flow of execution is stopped due to a failure. These should indicate a failure in the current activity, not an application-wide failure.

Return type:Microsoft.Extensions.Logging.LogLevel 
Error = 4
Information()

Logs that track the general flow of the application. These logs should have long-term value.

Return type:Microsoft.Extensions.Logging.LogLevel 
Information = 2
None()

Not used for writing log messages. Specifies that a logging category should not write any messages.

Return type:Microsoft.Extensions.Logging.LogLevel 
None = 6
Trace()

Logs that contain the most detailed messages. These messages may contain sensitive application data. These messages are disabled by default and should never be enabled in a production environment.

Return type:Microsoft.Extensions.Logging.LogLevel 
Trace = 0
Warning()

Logs that highlight an abnormal or unexpected event in the application flow, but do not otherwise cause the application execution to stop.

Return type:Microsoft.Extensions.Logging.LogLevel 
Warning = 3
