Trim value before reading

I have a csv i need to read that in a column it contains an integer value, but there is a space after the value, so the in the csv the value is "1,264 ".

In the class i have

public int MyValue { get; set; }

but when i try to ReadRecords i get the following error:

TypeConverterException: The conversion cannot be performed. Text: ‘1,264 ‘ MemberType: System.Int32 TypeConverter: ‘CsvHelper.TypeConversion.Int32Converter’ IReader state: ColumnCount: 0 CurrentIndex: 26 HeaderRecord:

Apparently i need to trim the empty space in the field. I have no control over the format of the initial format.

I could make it a string property and parse it at a second pass, but i want to see if there is another way.


I tried removing the space and still get the error. I had thought this might have been a culture info issue, and when i am reading i have the following code:

using (var reader = new StreamReader(@"C:tempfile.csv"))
using (var csv = new CsvReader(reader, new CsvConfiguration(new CultureInfo("en-US")) {
    TrimOptions = TrimOptions.Trim  
})) {...}


The code

Consider a file containing a header with a single column and a single row (besides the header):

"1,264 "


My current locale dictates that the comma is a decimal separator and the point is the thousands separator.


So, as already mentioned in the comments 1.264 is a double and trying to parse it as an integer will throw an exception. And the additional space is not a problem in a default CSV configuration:

public static class Program
    static void Main(string[] args)
        var csvContent = @"Id,Value
1,""1.236 """;

        List<Entry> entries;

        using (var reader = new StringReader(csvContent))
        using (var csvReader = new CsvReader(reader, CultureInfo.GetCultureInfo("en-us")))
            entries = csvReader.GetRecords<Entry>().ToList();

        foreach (var entry in entries)
            Console.WriteLine($"{entry.Id} {entry.Value}");

public class Entry
    public int Id { get; set; }
    public double Value { get; set; }
