CsvSerializer: The Fastest CSV Serializer for .NET

Installation

Package Manager Console:

Install-Package RG.CsvSerializer

Usage

using Csv;

// Serialize collection to CSV string
string csv = CsvSerializer.Serialize(items, withHeaders: true);

// Deserialize CSV string to array
Item[] items = CsvSerializer.Deserialize<Item>(csv, hasHeaders: true);

With custom delimiter:

Item[] items = CsvSerializer.Deserialize<Item>(csv, hasHeaders: true, separator: ';');

With custom header name and date format:

class Product {
    public string Name { get; set; }
    
    [CsvColumn("Price")]
    public decimal PriceBeforeTaxes { get; set; }
    
    [CsvColumn("Added", DateFormat = "dd/MM/yyyy")]
    public DateTime Added { get; set; }

    [CsvIgnore]
    public Category Category { get; set; }
}

Serializing to stream:

CsvSerializer.Serialize(streamWriter, items, withHeaders: true);

Deserializing from stream:

IEnumerable<Item> items = CsvSerializer.Deserialize<Item>(streamReader, hasHeaders: true);
