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 . And 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"
