How to VB.Net Stack
Stack is one of another easy to use VB.NET Collections . Stack follows the push-pop operations, that is we can Push Items into Stack and Pop it later also it follows the Last In First Out (LIFO) system. That is we can push the items into a stack and get it in reverse order. Stack returns the last item first.
Push : Add (Push) an item in the stack datastructure
Syntax : Stack.Push(Object)
Object : The item to be inserted.
Pop : Pop return the item last Item to insert in stack
Syntax : Stack.Pop()
Return : The last object in the Stack
Contains : Check the object contains in the stack
Syntax : Stack.Contains(Object)
Object : The specified Object to be seach
The following VB.NET Source code shows some of commonly used functions :
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles Button1.Click
Dim stackTable As New Stack
stackTable.Push("Sun")
stackTable.Push("Mon")
stackTable.Push("Tue")
stackTable.Push("Wed")
stackTable.Push("Thu")
stackTable.Push("Fri")
stackTable.Push("Sat")
If stackTable.Contains("Wed") Then
MsgBox(stackTable.Pop())
Else
MsgBox("not exist")
End If
End Sub
End Class |
When you execute this program add seven items in the stack . Then its checks the item "Wed" exist in the Stack. If the item exist in the Stack , it Pop the last item from Stack , else it shows the msg "Not Exist"
