วิธีการ Stack.ToArray() ใน C # ใช้เพื่อคัดลอก Stack ไปยังอาร์เรย์ใหม่
ไวยากรณ์
ไวยากรณ์มีดังนี้ −
public virtual object[] ToArray ();
ตัวอย่าง
เรามาดูตัวอย่างกัน −
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("\nStack elements...updated");
foreach(string val in stack) {
Console.WriteLine(val);
}
Console.WriteLine("\nCount 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("\nCopying the Stack to a new array...");
Object[] objArr = stack2.ToArray();
foreach(Object ob in objArr) {
Console.WriteLine(ob);
}
}
} ผลลัพธ์
สิ่งนี้จะสร้างผลลัพธ์ต่อไปนี้ -
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
