About

Just a simple extension to use with a standard ILogger from Microsoft.
Purpose is to add methods to write log messages with context. Caller class name, caller method name, line number.

How to

Install package with NuGet package manager or with dotnet add package command
A few methods can be used:

• LogWithContext - can write a log message with a LogLevel provided parameter.
• LogExceptionWithContext - will write down an exception.

A caller class name, method name and line number will be added to log output:

Code sample:

public class LogController : Controller
{
    private readonly ILogger<LogController> _logger;

    public LogController(ILogger<LogController> logger)
    {
        _logger = logger ?? throw new ArgumentNullException(nameof(logger));
    }

    [HttpPost]
    public IActionResult InformationalWithContext()
    {
        _logger.LogWithContext(LogLevel.Information, "Test informational message using context");
        return Ok();
    }

    [HttpPost]
    public IActionResult ExceptionWithContext()
    {
        var divider = 0;

        try
        {
            var result = 10 / divider;
        }
        catch (Exception ex)
        {
            _logger.LogExceptionWithContext("Test exception message using context", ex);
        }

        return Ok();
    }
}

Log output sample:

[INF] Test informational message using context (at LogController.InformationalWithContext, line 60)

Test exception message using context (at LogController.ExceptionWithContext, line 75)
System.DivideByZeroException: Attempted to divide by zero. at SerilogExtendedWebExample.Controllers.LogController.ExceptionWithContext()
