Poznámky

Tato vlastnost vrátí hodnotu vrácenou vyvoláním WriteTimeout v podkladovém datovém proudu. Pro operace sady nastaví zadaná hodnota WriteTimeout hodnotu v podkladovém datovém proudu.

Pokud je podkladový NetworkStreamdatový proud , WriteTimeout je v milisekundách a je ve výchozím nastavení nastavený na Infinite , aby operace zápisu nevypadaly na časový limit.
