Açıklamalar
WebNameözelliği özelliğiyle Name aynıdır.
Kodlama için WebName IANA'ya kayıtlı bir ad döndür olduğunu unutmayın. Değeri bir standardın adı olduğunda, kodlamanın uygulanması bu standarda tam olarak uymay olabilir. özelliği, HeaderName e-posta üst bilgileri için daha iyi çalışabilirsiniz farklı bir kodlama tanımlar. Ancak, çoğu uygulama bunun yerine kullan WebName gerekir.
IANA hakkında daha fazla bilgi için www.iana.org.
Encoding.WebName, tarafından döndürülen EncodingInfo.Name ile Encoding.GetEncodings aynıdır. Web adlarının bazıları yinelenen adlardır; Daha fazla bilgi için Encoding.GetEncodings açıklamalara bakın.
