法律研究C# 中的 Stack.ToArray() 方法
C# 中的 Stack.ToArray() 方法用于将栈复制到一个新数组中。
语法
语法如下 −
public virtual object[] ToArray ();
示例
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("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);
Console.WriteLine("
Copying the Stack to a new array...");
Object[] objArr = stack2.ToArray();
foreach(Object ob in objArr) {
Console.WriteLine(ob);
}
}
}输出
这将生成以下输出 −
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 Copying the Stack to a new array... Keyboards Cameras Ultrabook Notebook Laptop XPS Monitors Projectors Alienware Inspiron
示例
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(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);
Console.WriteLine("
Copying the Stack to a new array...");
Object[] objArr = stack.ToArray();
foreach(Object ob in objArr) {
Console.WriteLine(ob);
}
Console.WriteLine("
Count of elements in array = "+objArr.Length);
}
}输出
这将生成以下输出 −
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 Copying the Stack to a new array... 4000 3500 3000 2500 2000 1500 1250 1000 750 500 300 150 Count of elements in array = 12
