QuickLog.net

QuickLog.net is a simple .NET logging library

It supports logging:

• to the console
• to a file

Features

• Dependency injection via AddQuickLog(...)
• Basic log levels (Trace, `Error``)
• Console output with timestamp
• File output with automatic directory creation

Requirements

• .NET 10.0

Configuration

Configure it with DI:

using QuickLog.net;
using Microsoft.Extensions.DependencyInjection;

var services = new ServiceCollection();

services.AddQuickLog(options =>
{
	options.EnableConsoleLogging = true;
	options.EnableFileLogging = true;
	options.FileLoggingPath = "logs/exemple";
    options.AddDateToFileFormat = true;
});

Available options:

• EnableConsoleLogging (bool?): enables/disables console logging (default true)
• EnableFileLogging (bool?): enables/disables file logging (default false)
• FileLoggingPath (string?): log file path (for example logs/exemple)
• AddDateToFileFormat (bool?): enables/diasble date at the end of the file (for example logs/exemple260311.log)

Usage

Inject the logger:

using QuickLog.net.Logging;

public class App
{
	private readonly IQuickLog _quickLog;

	public App(IQuickLog quickLog)
	{
		_quickLog = quickLog;
	}

	public void Run()
	{
		_quickLog.LogTrace("Application started");
		_quickLog.LogError("This is a sample error log");
	}
}

Log Format

Each line is written using this format:

[yyyy-MM-dd HH:mm:ss] [LogType] message

Example:

[2026-03-10 14:30:12] [Trace] Application started

Log To A File

To write logs to a file, you must:

1. set EnableFileLogging = true
2. set FileLoggingPath

Valid example:

services.AddQuickLog(options =>
{
	options.EnableConsoleLogging = true;
	options.EnableFileLogging = true;
	options.FileLoggingPath = "logs/exemple";
});

The directory is created automatically if needed.

Run The Example

From the solution root:

dotnet run --project Exemple/Exemple.csproj

The file will be created here:

Exemple/logs/quicklog.log
