Namespace: LaunchDarkly.Logging
Assembly: LaunchDarkly.Logging.dll
Syntax
public class LogCapture : ILogAdapterRemarks
Calling Capture() provides a LogCapture object that accumulates
all log output from any code that is configured to use it as the log adapter. This is mainly
intended for testing.
All messages that come to this object are captured regardless of the log level. If you want to filter out messages below a certain level, you can apply Level(ILogAdapter, LogLevel) and pass the resulting filtered adapter to whatever component will be doing the logging, in place of the original LogCapture object.
Examples
var logSink = Logs.Capture(); // ... execute some code that produces log output to this adapter var capturedMessages = sink.GetMessages();
