Keterangan

Hati

WebRequest, , HttpWebRequestServicePoint, dan WebClient usang, dan Anda tidak boleh menggunakannya untuk pengembangan baru. Gunakan HttpClient sebagai gantinya.

Properti ContentType berisi jenis media permintaan. Nilai yang ditetapkan ke ContentType properti menggantikan konten yang ada saat permintaan mengirim Content-type header HTTP.

Untuk menghapus Content-type header HTTP, atur properti ke ContentTypenull.

Nota

Nilai untuk properti ini disimpan dalam WebHeaderCollection . Jika WebHeaderCollection diatur, nilai properti akan hilang.
