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 −
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("
Stack 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("
Stack 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 750 500 300 150 Count of elements = 9 Element 750 is the stack? = True Stack elements...updated 3000 2500 2000 1500 1250 1000 750 500 300 150 Count of elements (updated) = 10 Element 5000 is the stack? = False Stack elements...cloned 3000 2500 2000 1500 1250 1000 750 500 300 150 Count of elements (updated) = 10Is the Stack synchronized? = False Is the Stack synchronized? = True
Example
Let us now see another example −
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("
Stack elements...updated"); foreach(string val in stack) { Console.WriteLine(val); } Console.WriteLine("
Count 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
