Csharp/CSharp Tutorial/Generic/Generic Stack

Generic Stack based on generic Array

using System;
using System.Collections.Generic;
class MyStack<T> {
   int MaxStack = 10;
   
   T[] StackArray;
   int StackPointer = 0;
   public MyStack() {
      StackArray = new T[MaxStack];
   }
   public void Push(T x) {
      if (StackPointer < MaxStack)
         StackArray[StackPointer++] = x;
   }
   public T Pop() {
      return (StackPointer > 0)
                  ? StackArray[--StackPointer]
                  : StackArray[0];
   }
 
   public void Print()
   {
      for (int i = StackPointer - 1; i >= 0; i--)
         Console.WriteLine(" Value: {0}", StackArray[i]);
   }
}
class MainClass
{
   static void Main()
   {
      MyStack<int> StackInt = new MyStack<int>();
      MyStack<string> StackString = new MyStack<string>();
      StackInt.Push(3);
      StackInt.Push(7);
      StackInt.Print();
      StackString.Push("This is fun");
      StackString.Push("Hi there! ");
      StackString.Print();
   }
}

Value: 7
 Value: 3
 Value: Hi there!
 Value: This is fun

Push and pop value in a generic Stack<T>

using System;  
using System.Collections.Generic;  
   
class MainClass {  
  public static void Main() {  
    Stack<string> st = new Stack<string>();  
  
    st.Push("One");  
    st.Push("Two");  
    st.Push("Three");  
    st.Push("Four");  
    st.Push("Five");  
 
    while(st.Count > 0) { 
      string str = st.Pop(); 
      Console.Write(str + " "); 
    } 
 
    Console.WriteLine();  
  }  
}

Use generic Statck to store your own class

using System;        
using System.Collections.Generic;

class MainClass
{
    public static void Main(string[] args)
    {
        // Create and use a Stack of Assembly Name objects
        Stack<MyClass> stack = new Stack<MyClass>();
        stack.Push(new MyClass());
        MyClass ass3 = stack.Pop();
        Console.WriteLine("\nPopped from stack: {0}", ass3);
    }
}
class MyClass {
    
   public override string ToString(){
    
      return "my class";
   }
    
}

Popped from stack: my class
