Parameters

data  IEnumerableTSource

The data to convert to CSV. Each item will be represented with a CSV row.

converter  CsvFromTSource

An object that converts a TSource instance to a CSV row.

delimiter  Char  (Optional)

The field separator character.

columnNames  IReadOnlyCollectionString  (Optional)

A collection of column names for the header to be written, or null to use the PropertyNames of the CsvMapping as column names.

The collection determines the order in which the columns appear in the CSV file.

The collection will be copied. If the collection contains null values, empty strings, or white space, these are replaced by automatically generated column names. Column names cannot appear twice. By default the comparison is case-sensitive but it will be reset to a case-insensitive comparison if the column names are also unique when treated case-insensitive.

Type Parameters

TSource

Generic type parameter for the data type to write as CSV row.
