C＃のStack.IsSynchronizedプロパティ

C＃のStack.IsSynchronizedプロパティは、スタックへのアクセスが同期されているかどうか（スレッドセーフ）を示す値を取得するために使用されます。

構文

構文は次のとおりです-

public virtual bool IsSynchronized { get; }

例

例を見てみましょう-

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);
      Console.WriteLine("Element Speakers is the stack? = "+stack.Contains("Speakers"));
      stack.Push("Headphone");
      stack.Push("Keyboard");
      stack.Push("Earphone");
      Console.WriteLine("\nStack elements...updated");
      foreach(string val in stack) {
         Console.WriteLine(val);
      }
      Console.WriteLine("Count of elements (updated) = "+stack.Count);
      Console.WriteLine("\nElement Alienware is the stack? = "+stack.Contains("Alienware"));
      Console.WriteLine("Is the Stack synchronized? = "+stack.IsSynchronized);
      Stack stack2 = (Stack)stack.Clone();
      Console.WriteLine("\nStack elements...cloned");
      IEnumerator demoEnum = stack2.GetEnumerator();
      while (demoEnum.MoveNext()) {
         Console.WriteLine(demoEnum.Current);
      }
      Console.WriteLine("Count of elements (updated) = "+stack.Count);
   }
}
