PullStream.Csv

PullStream.Csv

PullStream.Csv allows to create lazy System.IO.Stream that contains csv representation of sequence of elements. PullStream.Csv uses PullStream, and therefore inherits all aspects of it.

Installation

Install NuGet package using Package Manager

Install-Package PullStream.Csv -Version 1.0.0

PullStream.Csv uses the CsvHelper package and supports a broad range of its versions. So, if it is desired to use a new version of CsvHelper package, direct reference to CsvHelper should be added.

Install-Package PullStream.Csv -Version 1.0.0
Install-Package CsvHelper -Version 27.0.2

Usage

using System.Collections.Generic;
using CsvHelper.Configuration;
using PullStream.Csv;

class Person
{
    public string Name { get; }
    public int Age { get; }
}

IEnumerable<Person> persons = ...;
var configuration = new CsvConfiguration(CultureInfo.InvariantCulture);
var stream = CsvStream.Of(persons, configuration, LastNewLine.No).Build();

The resulting stream will contain header and a row for each person in persons but no trailing newline. Encoding, newline characters, presence of header and other aspects of csv content are determined by CsvConfiguration. For example if header does not needed, one can use such a configuration

var configuration = new CsvConfiguration(CultureInfo.InvariantCulture)
{
    HasHeaderRecord = false
};

A way to create csv stream from IAsyncEnumerable is also presented and is similar.
