叠加。是 C# 中的同步属性
原文:https://www . geesforgeks . org/stack-is synchronized-property-in-c-sharp/
该方法(属于系统。Collections 命名空间)用于获取一个值,该值指示对堆栈的访问是否同步(线程安全)。为了保证堆栈的线程安全,所有操作都必须通过 Synchronized 方法返回的包装器来完成。此外,检索该属性的值是一个0(1)操作。
语法:
public virtual bool IsSynchronized { get; }
返回值:如果对堆栈的访问是同步的(线程安全的),该属性返回真,否则返回假。默认为假。
以下程序说明了上述属性的使用:
例 1:
// C# code to illustrate the
// Stack.IsSynchronized Property
using System;
using System.Collections;
class GFG {
// Driver code
public static void Main()
{
// Creating a Stack
Stack myStack = new Stack();
// Inserting the elements into the Stack
myStack.Push("Geeks");
myStack.Push("Geeks Classes");
myStack.Push("Noida");
myStack.Push("Data Structures");
myStack.Push("GeeksforGeeks");
// Creates a synchronized
// wrapper around the Stack
Stack ss = Stack.Synchronized(myStack);
// Displaying the synchronization
// status of both Stack
Console.WriteLine("myStack is {0}.", myStack.IsSynchronized ?
"Synchronized" : "Not Synchronized");
Console.WriteLine("ss is {0}.", ss.IsSynchronized ?
"Synchronized" : "Not Synchronized");
}
}
Output:
myStack is Not Synchronized.
ss is Synchronized.
例 2:
// C# code to illustrate the
// Stack.IsSynchronized Property
using System;
using System.Collections;
class GFG {
// Driver code
public static void Main()
{
// Creating a Stack
Stack myStack = new Stack();
// Inserting elements into Stack
myStack.Push("1st");
myStack.Push("2nd");
myStack.Push("3rd");
myStack.Push("4th");
myStack.Push("5th");
// the default is false for
// IsSynchronized property
Console.WriteLine(myStack.IsSynchronized);
}
}
Output:
False
