Keterangan
Properti WebName sama dengan Name properti .
Perhatikan bahwa WebName mengembalikan nama terdaftar IANA untuk pengodean. Ketika nilainya adalah nama standar, implementasi pengodean mungkin tidak sesuai secara penuh dengan standar tersebut. Properti HeaderName menentukan pengodean berbeda yang mungkin berfungsi lebih baik untuk header email. Namun, sebagian besar aplikasi harus menggunakan WebName sebagai gantinya.
Untuk informasi selengkapnya tentang IANA, buka www.iana.org.
Encoding.WebName sama dengan yang EncodingInfo.Name dikembalikan oleh Encoding.GetEncodings. Beberapa nama web adalah duplikat; lihat keterangan untuk Encoding.GetEncodings informasi selengkapnya.
