This method comes under the System.Collections.Generic namespace. Syntax: public T Pop (); Return Value: It returns the Object which is to be removed from the top of the Stack. Exception : This method will give InvalidOperationException if the Stack<T> is empty. Below programs illustrate the use of the above-discussed method: Example 1: csharp // C# Program to illustrate the // use of Stack<T>.Pop() Method using System; using System.Collections.Generic; class GFG { // Main Method public static void Main() { // Creating a Stack of Strings Stack<string> myStack = new Stack<string>(); // Inserting the elements into the 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); // Retrieveing top element of Stack Console.Write("Top element of Stack is: "); Console.Write(myStack.Pop()); // printing the no of Stack element // after Pop operation 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: csharp // C# Program to illustrate the // use of Stack<T>.Pop() Method using System; using System.Collections.Generic; class GFG { // Main Method public static void Main() { // Creating a Stack of integers Stack<int> myStack = new Stack<int>(); // Inserting the elements into the Stack myStack.Push(7); myStack.Push(9); Console.WriteLine("Number of elements in the Stack: {0}", myStack.Count); // Retrieveing top element of Stack Console.Write("Top element of Stack is: "); Console.Write(myStack.Pop()); // printing the no of Stack element // after Pop operation 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 Reference: https://docs.microsoft.com/en-us/dotnet/api/system.collections.generic.stack-1.pop?view=netframework-4.7.2 Comment More infoAdvertise with us K Kirti_Mangal Follow Improve Article Tags : C# CSharp-method CSharp-Generic-Stack CSharp-Generic-Namespace Similar Reads C# Tutorial C# (pronounced "C-sharp") is a modern, versatile, object-oriented programming language developed by Microsoft in 2000 that runs on the .NET Framework.
