How do I implement logging in C#?

You can use the built-in System.Diagnostics namespace or third-party libraries like NLog or log4net for logging.

Can you show me a simple example using NLog?

Sure! First, install the NLog package via NuGet. Then, configure it in your appsettings.json and use it like this:

private static readonly Logger logger = LogManager.GetCurrentClassLogger();

public void LogExample()
{
    logger.Info("This is an info message.");
}

What are the benefits of using a logging library?

Using a logging library provides structured logging, different log levels, and better performance compared to manual logging.

How can I log exceptions in NLog?

You can log exceptions by using the Error method. For example:

try
{
    // Your code here
}
catch (Exception ex)
{
    logger.Error(ex, "An error occurred.");
}
