The GoBack method of the HistoryStack<T> class is used to navigate backwards in the history stack. It returns the previous item in the stack, effectively moving the current position one step back.
The GoBack method of the HistoryStack<T> class is used to navigate backwards in the history stack. It returns the previous item in the stack, effectively moving the current position one step back.
Before calling GoBack, it is recommended to check if going back is possible by using the CanGoBack method. If CanGoBack returns true, you can safely call GoBack to retrieve the previous item.
// Assuming historyStack is an instance of HistoryStack<T>
if (historyStack.CanGoBack())
{
var previousItem = historyStack.GoBack();
// Use previousItem as needed
}
else
{
// Handle the case where you cannot go back
}
