Use case

The Serilog.Sinks.DelegatingText sink makes it possible buffer formatted log events in your application. For more information about Serilog, see Serilog.net and https://github.com/serilog/serilog.

private readonly StringBuilder  _logEventBuffer = new StringBuilder();

private void ConfigureApp()
{
    Log.Logger = new LoggerConfiguration()
        // Using a delegate to buffer log messages
        .WriteTo.DelegatingTextSink(w => WriteToBuffer(w), outputTemplate:"[{Timestamp:HH:mm:ss} {Level:u3}] {Message:lj}{NewLine}{Exception}")
        .CreateLogger();

    Log.Information("Hello from the sandbox");
    Log.Warning("Sample warning");
    Log.Error("Sample error");
    Log.Error(new Exception("A sample exception"), "Sample error with exception");

    // ...
}

private void WriteToBuffer(string formattedLogMessage)
{
    _logEventBuffer.AppendLine(formattedLogMessage.TrimEnd(Environment.NewLine.ToCharArray()));
}

private void SomeFunction()
{
    // do something with the buffered log events
    _logEventBuffer.ToString();
}
