Writing info message via fluent API.
Logger.Info()
.Message("This is a test fluent message '{0}'.", DateTime.Now.Ticks)
.Property("Test", "InfoWrite")
.Write();Writing error message.
try
{
string text = File.ReadAllText(path);
}
catch (Exception ex)
{
Logger.Error()
.Message("Error reading file '{0}'.", path)
.Exception(ex)
.Property("Test", "ErrorWrite")
.Write();
}Using thread-local properties.
public bool Run(int jobId)
{
try
{
Logger.ThreadProperties.Set("Job", jobId);
// all log writes on current thread will now include a Job property
Logger.Trace()
.Message("Starting Work ...")
.Write();
// DO WORK
return true;
}
catch (Exception ex)
{
Logger.Error()
.Message("Error: ", ex.Message)
.Exception(ex)
.Write();
return false;
}
finally
{
// clear Job property for this thread
Logger.ThreadProperties.Remove("Job");
}
}Using async properties.
public async Task<bool> Run(int jobId)
{
try
{
Logger.AsyncProperties.Set("Job", jobId);
return await DoWork();
}
catch (Exception ex)
{
Logger.Error()
.Message("Error: ", ex.Message)
.Exception(ex)
.Write();
return false;
}
finally
{
// clear Job property for this async context
Logger.AsyncProperties.Remove("Job");
}
}
public async Task<bool> DoWork()
{
// all log writes on current async context will now include a Job property
Logger.Trace()
.Message("Starting Work ...")
.Write();
// DO WORK
return true;

// example register of open generic for Autofac
builder.RegisterGeneric(typeof(LoggerFactory<>)).As(typeof(ILoggerFactory<>))To intergrate FluentLogger with NLog, install the FluentLogger.NLog source code nugget package.
PM> Install-Package FluentLogger.NLog
Then register the adapter with Logger on application startup as follows.
Logger.RegisterWriter(NLogWriter.Default);
To intergrate FluentLogger with log4net, install the FluentLogger.log4net source code nugget package.
PM> Install-Package FluentLogger.log4net
Then register the adapter with Logger on application startup as follows.
Logger.RegisterWriter(Log4NetWriter.Default);
