The CurrentIndex property of the HistoryStack<T> class provides the current position within the history stack. It indicates the index of the current item in the stack, allowing you to track which item is currently active or selected.
The CurrentIndex property of the HistoryStack<T> class provides the current position within the history stack. It indicates the index of the current item in the stack, allowing you to track which item is currently active or selected.
Use the CurrentIndex property to retrieve the index of the current item in the history stack. This can be useful for operations that depend on the current position, such as undo/redo functionality or navigating through a list of changes.
Note that the index is zero-based, meaning the first item in the stack has an index of 0.
// Example usage of the CurrentIndex property
// Assume we have a HistoryStack of strings
HistoryStack<string> historyStack = new HistoryStack<string>();
// Add some items to the history stack
historyStack.Add("State1");
historyStack.Add("State2");
historyStack.Add("State3");
// Retrieve the current index
int currentIndex = historyStack.CurrentIndex;
// Output the current index
// This will output 2 if the current state is "State3"
Console.WriteLine($"Current Index: {currentIndex}");
