//We declare the counter of number of intervals
//and set its initial value:
private int counter = 0; //by default too it is equal to 0.
//We declare and set the number N_Interval of intervals,
//after which one text is replaced by another:
private int N_Interval = 3;
private void timer1_Tick (object sender, EventArgs e)
{
//We check, value of the counter
//equally or yet is not present to number N_Interval of
//intervals,
//after which one text is replaced by another:
if (counter> = N_Interval)
{
//If value of the counter collected and is equal
//N_Interval, we output other text:
this. Text = «Calculator»;
//We nullify the value of the counter again:
counter = 0;
}
else
{
//If value of the counter did not collect yet
//and N_Interval is not equal,
//that we output the first text:
this. Text = «Calculator with animation»;
//We increase value of the counter on 1:
counter = counter +1;
}
}
И наконец, изучим третий вариант, когда анимация выполняется столько времени, какое число интервалов времени N_Interval_Stop мы задали, и после этого времени анимационный объект останавливается в заданном нами положении. Для этого в файле Form1.cs выше того же (что и в предыдущем варианте) автоматически сгенерированного шаблона метода объявляем большее число переменных, а в шаблон записываем более общий код, как показано на следующем листинге.
