How should we implement localization for exception message with CsvHelper?

[jobouillon]

I'm wondering if there is a way to localize easily all message from csvhelper?

What is the recommended or a good way to do this?

Header with name 'Test'[0] was not found. Headers: 'Test2' If you are expecting some headers to be missing and want to ignore this validation, set the configuration HeaderValidated to null. You can also change the functionality to do something else, like logging the issue. IReader state: ColumnCount: 1 CurrentIndex: -1 HeaderRecord: ["Test2"] IParser state: ByteCount: 0 CharCount: 12 Row: 1 RawRow: 1 Count: 1 RawRecord: Test2 IReader state: ColumnCount: 1 CurrentIndex: -1 HeaderRecord: ["Test2"] IParser state: ByteCount: 0 CharCount: 12 Row: 1 RawRow: 1 Count: 1 RawRecord: Test2

After looking up online, I have implemented a wrapper around csv helper and was plannig to translate receiving exception message by using localization resx file but it's ratter fastidious to convert all possible error messages.

I'm wondering if someone has achieve or know a better way to do this.

public static class CsvWrapperExtension
{
public static IEnumerable Read<T, TMap>(string filepath, CsvConfiguration csvConfiguration)
where TMap : ClassMap
{
try
{
//ValidateColumnCount<T, TMap>(filepath, csvConfiguration);
using var reader = new StreamReader(filepath, csvConfiguration.Encoding);
using var csv = new CsvReader(reader, csvConfiguration);

         csv.Context.TypeConverterCache = GetTypeConverterCache();
         csv.Context.TypeConverterOptionsCache.AddOptions<bool>(GetBoolTypeConverterOptionsCache());
         csv.Context.RegisterClassMap<TMap>();

         return csv.GetRecords<T>().ToList();
     }
     catch (CsvHelperException ex)
     {
         var translateMessage = Translate(ex);

         throw new ReaderException(ex.Context, translateMessage);
     }
     catch (Exception ex)
     {
         throw new InvalidOperationException("An error occurred while reading the CSV file.", ex);
     }
 }

 public static string Translate(Exception exception)
 {
     if (exception is ReaderException readerException)
     {
         if (readerException.Message.Contains("No header record was found."))
         {
             return "The CSV file is missing a header row. Please ensure the first row contains column names.";
         }

         if (readerException.Message.Contains("A field is missing from the header record."))
         {
             return "A required field is missing from the header row. Verify the column names match the expected format.";
         }

         if (readerException.Message.Contains("You can ignore missing fields by setting MissingFieldFound to null."))
         {
             return "The CSV file has missing fields. Update the configuration to handle missing fields or correct the file.";
         }

         return readerException.Message;
     }

     if (exception is ValidationException validationException)
     {
         return validationException.Message;
     }

     if (exception is TypeConverterException typeConverterException)
     {
         return $"A type conversion error occurred: {typeConverterException.Message}";
     }

     // Add more CsvHelper-specific error cases here as needed

     // Fallback for unknown exceptions
     return "An unknown error occurred while processing the CSV file. " + exception.Message;
 }

}
