Serilog: How to exclude several sources

I want to have several log files and I am trying to find a way to exclude several sources. This is my code:

Log.Logger = new LoggerConfiguration()
    .ReadFrom.Configuration(configuration)
    .Enrich.FromLogContext()
    .WriteTo.Console()
    .WriteTo.Logger(l => l.Filter.ByIncludingOnly(Matching.FromSource("Hangfire"))
        .WriteTo.Async(a => a.RollingFile("Logs/hangfire-{Date}.txt"))
    )
    .WriteTo.Logger(l => l.Filter.ByExcluding(Matching.FromSource("Hangfire"))
        .WriteTo.Async(a => a.RollingFile("Logs/main-{Date}.txt"))
    )
    .CreateLogger();

As you can see I have sub loggers: first collects hangfire logs only, second one all logs except of hangfire. But, I want to add another excluding filter, for examle, I want to exclude hangfire and IMyClass logs. How can I do it?

Matching.FromSource() return a function from LogEvent to bool. You can take advantage of that to create two filter functions:

var hangfire = Matching.FromSource("Hangfire");
var myClass = Matching.FromSource("MyClass");

And then call them inline:

.WriteTo.Logger(l => l.Filter.ByExcluding(le => myClass(le) || hangfire(le))
    .WriteTo.Async(a => a.RollingFile("Logs/main-{Date}.txt"))
)
