Примеры

В этом примере демонстрируется SetWindowSize метод, а также WindowHeight WindowWidth свойства и.This example demonstrates the SetWindowSize method, and the WindowWidth and WindowHeight properties. Чтобы увидеть полный результат изменения размера окна консоли, необходимо выполнить пример.You must run the example to see the full effect of changing the console window size.

Пример сообщает размерам окна консоли, для которых задано значение 85 столбцов и 43 строк, а затем ожидает нажатия клавиши.The example reports the dimensions of a console window set to 85 columns and 43 rows, then waits for a key press. При нажатии любой клавиши размеры окна консоли увеличиваются вдвое, выводятся новые измерения, а в примере ожидается еще один нажатие клавиши.When any key is pressed, the dimensions of the console window are halved, the new dimensions are reported, and the example waits for another key press. Наконец, при нажатии любой клавиши окно консоли восстанавливается до исходных измерений, а пример завершается.Finally, when any key is pressed the console window is restored to its original dimensions and the example terminates.

Попытка задать значение WindowWidth свойства при перенаправлении ArgumentOutOfRangeException вывода вызывает исключение или IOException .Attempting to set the value of the WindowWidth property when output is redirected throws either an ArgumentOutOfRangeException or an IOException exception. Чтобы предотвратить исключение, значение этого свойства можно задать только в IsOutputRedirected том случае, если свойство возвращает. falseTo prevent an exception, you can set the value of this property only if the IsOutputRedirected property returns false.
