C＃Stack.CopyTo()方法 (C# Stack.CopyTo() method)

Stack.CopyTo() method is used to copy the stack elements/objects to an existing array from the given index.

Stack.CopyTo()方法用于将堆栈元素/对象从给定索引复制到现有数组。

Syntax:

句法：

    void Stack.CopyTo(Array, Int32);

Parameters: Array – Targeted array_name in which we have to copy the stack elements/objects, Int32 – is an index in targeted array_name from where stack elements/objects are copied.

参数： Array – 必须在其中复制堆栈元素/对象的目标array_name ， Int32 –是目标array_name中从中复制堆栈元素/对象的索引。

Return value: void – it returns nothing.

返回值： void –不返回任何内容。

Example:

例：

    declare and initialize a stack:
Stack stk = new Stack();
an array declaration for 20 elements:
int[] arr = new int[20];
insertting elements:
stk.Push(100);
stk.Push(200);
stk.Push(300);
stk.Push(400);
stk.Push(500);
using CopyTo(), copying stack elements to the array:
stk.CopyTo(arr, 3); //will copy from 3rd index in array
Output:
arr: 0 0 0 500 400 300 200 100 0 0 0 0 0 0 0 0 0 0 0 0

使用Stack.CopyTo()方法将堆栈元素/对象复制到数组的C＃示例 (C# example to copy stack elements/objects to an array using Stack.CopyTo() method)

using System;
using System.Text;
using System.Collections;
namespace Test
{class Program
{//function to print stack elements
static void printStack(Stack s)
{foreach (Object obj in s)
{Console.Write(obj + " ");
}
Console.WriteLine();
}
static void Main(string[] args)
{//declare and initialize a stack
Stack stk = new Stack();
//an array declaration for 20 elements
int[] arr = new int[20];
//insertting elements
stk.Push(100);
stk.Push(200);
stk.Push(300);
stk.Push(400);
stk.Push(500);
//printing stack elements
Console.WriteLine("Stack elements are...");
printStack(stk);
//printing array
Console.WriteLine("Array elements before CopyTo()...");
foreach (int item in arr)
{Console.Write(item + " ");
}
Console.WriteLine();
//using CopyTo(), copying stack elements to the array
stk.CopyTo(arr, 3);
//printing array
Console.WriteLine("Array elements after CopyTo()...");
foreach (int item in arr)
{Console.Write(item + " ");
}
Console.WriteLine();
//hit ENTER to exit
Console.ReadLine();
}
}
}

Output

输出量

Stack elements are...
500 400 300 200 100
Array elements before CopyTo()...
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Array elements after CopyTo()...
0 0 0 500 400 300 200 100 0 0 0 0 0 0 0 0 0 0 0 0
