CombineUrl Logging Helper

The CombineUrl method offers a safe, reusable way to concatenate a base URI and path string for logging purposes. It is wrapped in a try-catch block to avoid exceptions from malformed input, making it reliable for use in production logging. This method returns a string and can be placed inside a centralized LoggingHelpers class for consistent use across the codebase.

public static class LoggingHelpers
{
    public static string CombineUrl(Uri? baseAddress, string path)
    {
        try
        {
            if (string.IsNullOrWhiteSpace(path))  return baseAddress?.ToString() ?? string.Empty;

            if (baseAddress == null)  return path;

            return new Uri(baseAddress, path).ToString();
        }
        catch (Exception ex)
        {
            return $"[InvalidUrl: {ex.Message}]";
        }
    }
}
