How can I implement logging for audit trails in C#?

You can use libraries like NLog or Serilog to implement logging in C#. They allow you to log events and track changes.

What kind of information should I log for audit trails?

You should log user actions, timestamps, and any changes made to data. This helps in tracking who did what and when.

Can you show me a code example using Serilog?

Sure! Here's a simple example:

Log.Logger = new LoggerConfiguration()
    .WriteTo.File("audit.log")
    .CreateLogger();

Log.Information("User {UserId} updated record {RecordId} at {Time}", userId, recordId, DateTime.Now);

How do I ensure the logs are secure?

You can secure logs by restricting access to log files, using encryption, and ensuring that sensitive information is not logged.
