Hodnota vlastnosti

Šířka okna konzoly měřená ve sloupcích.

Atributy

Výjimky

Hodnota WindowWidth vlastnosti nebo hodnoty WindowHeight vlastnosti je menší nebo rovna 0.

nebo

Hodnota WindowHeight vlastnosti plus hodnota WindowTop vlastnosti je větší nebo rovna Int16.MaxValue.

nebo

Hodnota WindowWidth vlastnosti nebo hodnoty WindowHeight vlastnosti je větší než největší možná šířka nebo výška okna pro aktuální rozlišení obrazovky a písmo konzoly.

Operace set je vyvolána v jiném operačním systému než Windows.

Příklady

Tento příklad ukazuje metodu SetWindowSize a WindowWidth vlastnosti WindowHeight . Pokud chcete zobrazit úplný efekt změny velikosti okna konzoly, musíte spustit příklad.

Příklad hlásí rozměry okna konzoly nastavené na 85 sloupců a 43 řádků a pak čeká na stisknutí klávesy. Při stisknutí libovolné klávesy jsou rozměry okna konzoly o polovinu, nové dimenze jsou hlášeny a příklad čeká na další stisknutí klávesy. A konečně, když je stisknuta libovolná klávesa okna konzoly se obnoví do původních rozměrů a příklad se ukončí.

Poznámky

Pokus o nastavení hodnoty WindowWidth vlastnosti při přesměrování ArgumentOutOfRangeException výstupu vyvolá výjimku nebo výjimku IOException . Chcete-li zabránit výjimce, můžete nastavit hodnotu této vlastnosti pouze v případě, že IsOutputRedirected vlastnost vrátí false.
