法律研究C# 中的 Stack.Clone() 方法
C# 中的 Stack.Clone() 方法用于创建 Stack 的浅层副本。
语法
语法如下 −
public virtual object Clone ();
示例
让我们举个示例 −
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);
stack.Push(3000);
stack.Push(3500);
stack.Push(4000);
Console.WriteLine("
Stack elements...updated");
foreach(int val in stack){
Console.WriteLine(val);
}
Console.WriteLine("
Count of elements (updated) = "+stack.Count);
Stack stack2 = (Stack)stack.Clone();
Console.WriteLine("
Stack elements...cloned");
foreach(int val in stack2){
Console.WriteLine(val);
}
Console.Write("Count of elements in cloned stack(updated) ="+stack2.Count);
}
}输出
将生成以下输出 −
Stack elements... 2500 2000 1500 1250 1000 750 500 300 150 Count of elements = 9 Stack elements...updated 4000 3500 3000 2500 2000 1500 1250 1000 750 500 300 150 Count of elements (updated) = 12 Stack elements...cloned 4000 3500 3000 2500 2000 1500 1250 1000 750 500 300 150 Count of elements in cloned stack(updated) = 12
示例
让我们再举一个示例 −
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("Headphone");
stack.Push("Keyboard");
stack.Push("Earphone");
Console.WriteLine("
Stack elements...updated");
foreach(string val in stack){
Console.WriteLine(val);
}
Console.WriteLine("Count of elements (updated) = "+stack.Count);
Stack stack2 = (Stack)stack.Clone();
Console.WriteLine("
Stack elements...cloned");
foreach(string val in stack2){
Console.WriteLine(val);
}
Console.Write("Count of elements (updated) = "+stack2.Count);
}
}输出
将生成以下输出 −
Stack elements... Notebook Laptop XPS Monitors Projectors Alienware Inspiron Count of elements = 7 Stack elements...updated Earphone Keyboard Headphone Notebook Laptop XPS Monitors Projectors Alienware Inspiron Count of elements (updated) = 10 Stack elements...cloned Earphone Keyboard Headphone Notebook Laptop XPS Monitors Projectors Alienware Inspiron Count of elements (updated) = 10
