How can I implement logging and error handling in C#?

How can I implement logging and error handling in C#?

You can use libraries like NLog or log4net for logging. For error handling, try using try-catch blocks.

Can you show me a simple example of using NLog?

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

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

What about logging to a file?

You can configure NLog to log to a file by adding a target in your NLog.config:

<targets>
  <target name="file" xsi:type="File" fileName="logs/app.log" />
</targets>

How do I handle exceptions globally in an ASP.NET application?

You can use middleware to handle exceptions globally. Implement a custom middleware that catches exceptions and logs them.
