เมธอด Stack.Equals() ใน C# ใช้สำหรับตรวจสอบว่า Stack Class Object เท่ากับ Object อื่นหรือไม่
Syntax
public virtual bool Equals (object ob);
พารามิเตอร์ ob คือ Object ที่จะเปรียบเทียบ
ตัวอย่าง
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("\nStack elements...updated");
foreach(int val in stack){
Console.WriteLine(val);
}
Console.WriteLine("\nCount of elements (updated) = " + stack.Count);
Stack stack2 = (Stack)stack.Clone();
Console.WriteLine("\nStack elements...cloned");
foreach(int val in stack2){
Console.WriteLine(val);
}
Console.Write("Count of elements in cloned stack (updated) = " + stack2.Count);
Console.WriteLine("\nAre both the stacks equal? = " + stack.Equals(stack2));
}
}
ผลลัพธ์
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 Are both the stacks equal? = False
