Attribute in CsvHelper
CsvConstantAttribute
Added in v34.0.0
Gives a member of a CsvRecordAttribute type a fixed value instead of reading a column: every record read gets Value, and the record writer writes it in the member's column, whatever the member holds.

Remarks
The value must be a constant that converts implicitly to the member's type, or null for a reference type or a Nullable<T>. The header does not need the column. The column's other attributes, such as its name and CsvColumnAttribute.Index, still say where the record writer writes it.
