Is it possible to elegantly configure Serilog with if-statements?

Question

My Serilog configuration code looks like this:

Log.Logger = new LoggerConfiguration()
    .Enrich.WithExceptionDetails()
    .Enrich.FromLogContext()
    .Mi         


        

Answer 1

Serilog 2.9.0 introduces conditional sinks. Using .WriteTo.Conditional you specify the condition that defines if the sink will be written to or not.

e.g.

bool enableConsoleLogging = ...
bool enableFileLogging = ...

var builder = new LoggerConfiguration()
    .Enrich.WithExceptionDetails()
    .Enrich.FromLogContext()
    .MinimumLevel.Warning()
    .WriteTo.Conditional(evt => enableConsoleLogging, wt => wt.Console())
    .WriteTo.Conditional(evt => enableFileLogging, wt => wt.File(...));

Log.Logger = builder.CreateLogger();
// ...
