In VB.net, the
Stack data structure is implemented as a class in the
To use the
Stack class, you first need to import the
System.Collections namespace into your project.
Here's an example of using the
Stack class in VB.net:
' Create a new stack Dim stack As New Stack() ' Push items onto the stack stack.Push("Item 1") stack.Push("Item 2") stack.Push("Item 3") ' Pop an item from the stack Dim item As Object = stack.Pop() ' Peek at the top item on the stack without removing it Dim topItem As Object = stack.Peek() ' Check if the stack contains an item If stack.Contains("Item 2") Then Console.WriteLine("Stack contains Item 2") End If ' Get the number of items on the stack Dim count As Integer = stack.Count() ' Clear all items from the stack stack.Clear()
In this example, we create a new
Stack object and push some items onto it. We then use the
Pop method to remove an item from the top of the stack and the
Peek method to peek at the top item without removing it. We also use the
Contains method to check if the stack contains a certain item, the
Count property to get the number of items on the stack, and the
Clear method to remove all items from the stack.
