This method(comes under System.Collections namespace) is used to remove and returns the object at the top of the Stack. This method is similar to the Peek method, but Peek does not modify the Stack.
Syntax:
public virtual object Pop ();
Return Value: It returns the Object removed from the top of the Stack.
Exception : This method will give InvalidOperationException if the Stack is empty.
Below programs illustrate the use of the above-discussed method:
Example 1:
using System;
using System.Collections;
class GFG {
public static void Main()
{
Stack myStack = new Stack();
myStack.Push( "Geeks" );
myStack.Push( "Geeks Classes" );
myStack.Push( "Noida" );
myStack.Push( "Data Structures" );
myStack.Push( "GeeksforGeeks" );
Console.WriteLine( "Number of elements in the Stack: {0}" ,
myStack.Count);
Console.Write( "Top element of Stack is: " );
Console.Write(myStack.Pop());
Console.WriteLine( "\nNumber of elements in the Stack: {0}" ,
myStack.Count);
}
}
|
Output:
Number of elements in the Stack: 5
Top element of Stack is: GeeksforGeeks
Number of elements in the Stack: 4
Example 2:
using System;
using System.Collections;
class GFG {
public static void Main()
{
Stack myStack = new Stack();
myStack.Push(7);
myStack.Push(9);
Console.WriteLine( "Number of elements in the Stack: {0}" ,
myStack.Count);
Console.Write( "Top element of Stack is: " );
Console.Write(myStack.Pop());
Console.WriteLine( "\nNumber of elements in the Stack: {0}" ,
myStack.Count);
}
}
|
Output:
Number of elements in the Stack: 2
Top element of Stack is: 9
Number of elements in the Stack: 1
