Stack.Synchronized() Method in C#


The Stack.Synchronized() method in C# is used to returns a synchronized (thread safe) wrapper for the Stack.

Syntax

The syntax is as follows −

public static System.Collections.Stack Synchronized (System.Collections.Stack stack);

Above, the parameter stack is the stack to synchronize.

Example

Let us now see an example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      Stack stack = new Stack();
      stack.Push(150);
      stack.Push(300);
      stack.Push(500);
      stack.Push(750);
      stack.Push(1000);
      stack.Push(1250);
      stack.Push(1500);
      stack.Push(2000);
      stack.Push(2500);
      Console.WriteLine("Stack elements...");
      foreach(int val in stack) {
         Console.WriteLine(val);
      }
      Console.WriteLine("Count of elements = "+stack.Count);
      Console.WriteLine("Element 750 is the stack? = "+stack.Contains(750));
      stack.Push(3000);
      Console.WriteLine("\nStack elements...updated");
      foreach(int val in stack) {
         Console.WriteLine(val);
      }
      Console.WriteLine("Count of elements (updated) = "+stack.Count);
      Console.WriteLine("Element 5000 is the stack? = "+stack.Contains(5000));
      Stack stack2 = (Stack)stack.Clone();
      Console.WriteLine("\nStack elements...cloned");
      foreach(int val in stack2) {
         Console.WriteLine(val);
      }
      Console.Write("Count of elements (updated) = "+stack2.Count);
      Console.WriteLine("Is the Stack synchronized? = "+stack.IsSynchronized);
      Stack stack3 = Stack.Synchronized(stack);
      Console.WriteLine("Is the Stack synchronized? = "+stack3.IsSynchronized);
   }
}

Output

This will produce the following output −

Stack elements...
2500
2000
1500
1250
1000
750
500
300

Count of elements = 9
Element 750 is the stack? = True

Element 5000 is the stack? = False

Is the Stack synchronized? = True

Example

Let us now see another example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      Stack stack = new Stack();
      stack.Push("Inspiron");
      stack.Push("Alienware");
      stack.Push("Projectors");
      stack.Push("Monitors");
      stack.Push("XPS");
      stack.Push("Laptop");
      stack.Push("Notebook");
      Console.WriteLine("Stack elements...");
      foreach(string val in stack) {
         Console.WriteLine(val);
      }
      Console.WriteLine("Count of elements = "+stack.Count);
      stack.Push("Ultrabook");
      stack.Push("Cameras");
      stack.Push("Keyboards");
      Console.WriteLine("\nStack elements...updated");
      foreach(string val in stack) {
         Console.WriteLine(val);
      }
      Console.WriteLine("\nCount of elements (updated) = "+stack.Count);
      Console.WriteLine("Is the Stack synchronized? = "+stack.IsSynchronized);
      Stack stack2 = Stack.Synchronized(stack);
      Console.WriteLine("Is the Stack synchronized? = "+stack2.IsSynchronized);
   }
}

Output

This will produce the following output −

Stack elements...
Notebook
Laptop
XPS
Monitors
Projectors
Alienware
Inspiron
Count of elements = 7
Stack elements...updated
Keyboards
Cameras
Ultrabook
Notebook
Laptop
XPS
Monitors
Projectors
Alienware
Inspiron
Count of elements (updated) = 10
Is the Stack synchronized? = False
Is the Stack synchronized? = True
