# Mapping by Alternate Names

If you have a header name that could vary, you can specify multiple header names.

###### Data

    Id,Name
    1,one

###### 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 Name { get set; }
    }

    public sealed class FooMap : ClassMap<Foo>
    {
        public FooMap()
        {
            Map(m => m.Id).Name("TheId", "Id");
            Map(m => m.Name).Name("TheName", "Name");
        }
    }
