The ```Stack<T>``` generic class in the ```System.Collections.Generic``` namespace provides the **```Pop()```** method, which can be used to remove and return the element present at the top of a stack in C#.

#   
#  Syntax
```c#
public T Pop ();
```
- This method removes and returns the value of T type present at the top of the stack.

##  
## Things to note
- This method is an $O(1)$ operation.
- It modifies the state of the stack.
- It throws an ```InvalidOperationException``` if the stack is empty.

#   
## Code
In the following code, we create a stack of strings.

First, we call the ```Push()``` method with the `Lion`, `Tiger`, and `Panther` strings. This inserts all three strings onto the stack, with `Panther` at the top of the stack.

We then show all the elements of the stack, and we can see that the stack has `Panther` at the top, followed by `Tiger` and `Lion`.

We now call the ```Pop()``` method and save the returned value in a local variable.  `Pop()` removes and returns the `Panther` element present at the top of the stack since the stack is a #key# LIFO: Last In First Out #key# data structure.

Then, we again display all of the elements of the stack and can observe that now, `Tiger` is at the top of the stack and `Panther` is removed.

using System;
using System.Collections.Generic;

class StackPop
{
    static void Main()
    {
        Stack<string> stack = new Stack<string>();
        stack.Push("Lion");
        stack.Push("Tiger");     
        stack.Push("Panther");
        Console.WriteLine("Current stack items: \n{0}\n", string.Join(",", stack.ToArray()));
        string item = stack.Pop();
        Console.WriteLine($"Removed {item} from the top of the stack.\n");       
        Console.WriteLine("Stack items:\n{0}", string.Join(",", stack.ToArray()));

    }
}
