How do I log exceptions in C#?

You can log exceptions in C# using try-catch blocks and a logging framework like NLog or log4net.

Can you show me a simple example using NLog?

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

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

What if I want to log to a file?

You can configure NLog to log to a file by setting the target in your NLog configuration:

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

Are there any best practices for logging exceptions?

Yes, always log the exception message and stack trace, and avoid logging sensitive information.
