Stack.Contains() পদ্ধতিটি C#-এ একটি উপাদান স্ট্যাকের মধ্যে আছে কিনা তা পরীক্ষা করার জন্য ব্যবহার করা হয়।
সিনট্যাক্স
সিনট্যাক্স নিম্নরূপ -
public virtual bool Contains (object ob);
উপরে, ob হল বস্তুটি যা স্ট্যাকের মধ্যে অনুসন্ধান করা হবে।
উদাহরণ
আসুন এখন একটি উদাহরণ দেখি -
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);
Console.WriteLine("Element Speakers is the stack? = "+stack.Contains("Speakers"));
stack.Push("Headphone");
stack.Push("Keyboard");
stack.Push("Earphone");
Console.WriteLine("\nStack elements...updated");
foreach(string val in stack) {
Console.WriteLine(val);
}
Console.WriteLine("Count of elements (updated) = "+stack.Count);
Console.WriteLine("Element Alienware is the stack? = "+stack.Contains("Alienware"));
Stack stack2 = (Stack)stack.Clone();
Console.WriteLine("\nStack elements...cloned");
foreach(string val in stack2) {
Console.WriteLine(val);
}
Console.Write("Count of elements (updated) = "+stack2.Count);
}
} আউটপুট

উদাহরণ
এখন আরেকটি উদাহরণ দেখা যাক -
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);
Console.WriteLine("Element 750 is the stack? = "+stack.Contains(750));
stack.Push(3000);
Console.WriteLine("\nStack elements...updated");
foreach(int val in stack) {
Console.WriteLine(val);
}
Console.WriteLine("Count of elements (updated) = "+stack.Count);
Console.WriteLine("Element 5000 is the stack? = "+stack.Contains(5000));
Stack stack2 = (Stack)stack.Clone();
Console.WriteLine("\nStack elements...cloned");
foreach(int val in stack2) {
Console.WriteLine(val);
}
Console.Write("Count of elements (updated) = "+stack2.Count);
}
} আউটপুট
