Usage 🛠️

Deserialization (Reading vCards)

From a File

string filePath = // path to .vcf file;
IEnumerable<vCard> contacts = vCardDeserializer.FromFile(filePath);

From a Stream

var stream = // generate stream containing serialized vCards
IEnumerable<vCard> contacts = vCardDeserializer.FromStream(stream);

From a String

var contactDetails = @"BEGIN:VCARD
VERSION:2.1
N:John;Doe;;;
END:VCARD";
IEnumerable<vCard> contacts = vCardDeserializer.FromContent(contactDetails);

---

Serialization (Writing vCards)

Serialize as String

var vcard = new vCard(vCardVersion.V2)
{
    FormattedName = "John Doe"
};
var serialized = vCardSerializer.Serialize(vcard);

/*
Output:
BEGIN:VCARD
VERSION:2.1
REV:20230719T001838Z
FN:John Doe
END:VCARD
*/

Serialize with Version Override

var vcard = new vCard(vCardVersion.V2)
{
    FormattedName = "John Doe"
};
var serialized = vCardSerializer.Serialize(vcard, vCardVersion.V4);

/*
Output:
BEGIN:VCARD
VERSION:4.0
REV:20230719T001838Z
FN:John Doe
END:VCARD
*/
