Keterangan

Properti ini mengembalikan nilai yang dikembalikan dengan memanggil ReadTimeout pada aliran yang mendasar. Saat Anda mengatur properti ini, ReadTimeout nilai pada aliran yang mendasar diatur ke nilai yang ditentukan.

Jika aliran yang mendasar adalah NetworkStream, ReadTimeout dalam milidetik dan diatur ke Infinite secara default sehingga operasi baca tidak batas waktu.
