直接给你上源码了：
LoggerConfiguration loggerConfiguration = new LoggerConfiguration();

     loggerConfiguration
        .Enrich.FromLogContext()
        .Enrich.WithProperty("source", "xxx-yyy")
        .Enrich.WithProperty("test", "test9999");

LoggerConfiguration loggerConfiguration = new LoggerConfiguration();

     loggerConfiguration
        .Enrich.FromLogContext()
        .Enrich.WithProperty("source", "xxx-yyy")
        .Enrich.WithProperty("test", "test9999");
