法律研究C# 中的 Stack.Synchronized() 方法
C# 中的 Stack.Synchronized() 方法用于返回堆栈的同步（线程安全）包装器。
语法
语法如下所示 −
public static System.Collections.Stack Synchronized (System.Collections.Stack stack);
上面，参数 stack 是要同步的 stack。
示例
现在让我们看一个示例 −
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);
}
}输出
这将产生以下输出 −
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
示例
现在让我们看另一个示例 −
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);
}
}输出
这将产生以下输出 −
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
