C# में Stack.CopyTo() विधि का उपयोग स्टैक को मौजूदा एक-आयामी सरणी में कॉपी करने के लिए किया जाता है, जो निर्दिष्ट सरणी अनुक्रमणिका से शुरू होता है।
सिंटैक्स
वाक्य रचना इस प्रकार है -
public virtual void CopyTo (Array arr, int index);
ऊपर, पैरामीटर arr एक-आयामी ऐरे है जो स्टैक से कॉपी किए गए तत्वों का गंतव्य है, जबकि इंडेक्स वह इंडेक्स है जिस पर कॉपी शुरू होती है।
उदाहरण
आइए अब एक उदाहरण देखें -
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.WriteLine("Count of elements (updated) = "+stack2.Count);
Console.WriteLine("\nCopying the cloned stack to an integer array...");
int[] intArr = new int[stack2.Count];
stack2.CopyTo(intArr, 0);
foreach(int j in intArr){
Console.WriteLine(j);
}
}
} आउटपुट
यह निम्नलिखित आउटपुट देगा -

using System;
using System.Collections;
