How do I use try-catch in ASP.NET Core?

In ASP.NET Core, you can use try-catch blocks to handle exceptions. Wrap your code that might throw an exception in a try block, and handle the exception in the catch block.

Can you give me an example of that?

Sure! Here's a simple example:

try {
    // Code that may throw an exception
    var result = await _service.GetDataAsync();
} catch (Exception ex) {
    // Handle the exception
    _logger.LogError(ex, "An error occurred while getting data.");
}

What types of exceptions should I catch?

It's best to catch specific exceptions rather than a general Exception. For example, catch NullReferenceException or HttpRequestException to handle specific error scenarios.

Is there a way to globally handle exceptions in ASP.NET Core?

Yes, you can use middleware to handle exceptions globally. Implement a custom middleware that catches exceptions and returns a standardized error response.
