Microsoft.Extensions.Logging.TraceSource 10.0.9

About

Implements a trace logger provider for the .NET logging infrastructre facilitating enhanced logging capabilities and trace-level diagnostics in application by writing messages to a trace listener using System.Diagnostic.TraceSource.

Key Features

• Seamless integration with .NET logging infrastructure.
• Fine-grained control over trace messages using SourceSwitch.
• A set of builder methods to configure logging infrastructure.

How to Use

The Microsoft.Extensions.Logging.TraceSource library provides extension methods to the logger factory and the logger builder to add a trace source with trace listeners.

using System.Diagnostics;
using Microsoft.Extensions.Logging;

using var consoleTraceListener = new ConsoleTraceListener();
using var textWriterTraceListener = new TextWriterTraceListener("/traces.txt");
using var loggerFactory = LoggerFactory.Create(builder =>
{
 builder
 .AddTraceSource(new SourceSwitch("Something") { Level = SourceLevels.All }, consoleTraceListener)
 .AddTraceSource(new SourceSwitch("HouseKeeping") { Level = SourceLevels.All }, textWriterTraceListener);
});

var logger = loggerFactory.CreateLogger<Program>();

logger.LogInformation("Information message.");
// Program Information: 0 : Information message.
logger.LogWarning("Warning message.");
// Program Warning: 0 : Warning message.

var traceSource = new TraceSource("HouseKeeping", SourceLevels.All);
traceSource.Listeners.Add(consoleTraceListener);
traceSource.Listeners.Add(textWriterTraceListener);

traceSource.TraceEvent(TraceEventType.Error, 0, "Error message.");
//HouseKeeping Error: 0 : Error message.
