Mapping Duplicate Names

Sometimes you have duplicate header names. This is handled through a header name index. The name index is the index of how many occurrences of that header name there are, not the position of the header.

Data

Id,Name,Name
1,first,last

Example

void Main()
{
    using (var reader = new StreamReader("path\\to\\file.csv"))
    using (var csv = new CsvReader(reader, CultureInfo.InvariantCulture))
    {
        csv.Context.RegisterClassMap<FooMap>();
        var records = csv.GetRecords<Foo>();
    }
}

public class Foo
{
    public int Id { get; set; }
    public string FirstName { get set; }
	public string LastName { get; set; }
}

public sealed class FooMap : ClassMap<Foo>
{
    public FooMap()
    {
        Map(m => m.Id);
        Map(m => m.FirstName).Name("Name").NameIndex(0);
		Map(m => m.LastName).Name("Name").NameIndex(1);
    }
}
