Stack.ToArray() Method in C# (original) (raw)

Last Updated : 04 Feb, 2019

This method(comes under System.Collections namespace) is used to copy a Stack to a new array. The elements are copied onto the array in last-in-first-out (LIFO) order, similar to the order of the elements returned by a succession of calls to Pop. This method is an O(n) operation, where n is Count.Syntax:

public virtual object[] ToArray ();

Return Type: This method returns a new array of type System.Object containing copies of the elements of the Stack. Below given are some examples to understand the implementation in a better way:Example 1:

CSHARP `

// C# code to illustrate the // Stack.ToArray() Method using System; using System.Collections;

class GFG {

// Driver code
public static void Main()
{

    // Creating a Stack
    Stack myStack = new Stack();

    // Inserting the elements into the Stack
    myStack.Push("Geeks");
    myStack.Push("Geeks Classes");
    myStack.Push("Noida");
    myStack.Push("Data Structures");
    myStack.Push("GeeksforGeeks");

    // Converting the Stack into array
    Object[] arr = myStack.ToArray();

    // Displaying the elements in array
    foreach(Object str in arr)
    {
        Console.WriteLine(str);
    }
}

}

`

Output:

GeeksforGeeks Data Structures Noida Geeks Classes Geeks

Example 2:

CSHARP `

// C# code to illustrate the // Stack.ToArray() Method using System; using System.Collections;

class GFG {

// Driver code
public static void Main()
{

    // Creating a Stack
    Stack myStack = new Stack();

    // Inserting the elements into the Stack
    myStack.Push(2);
    myStack.Push(3);
    myStack.Push(4);
    myStack.Push(5);
    myStack.Push(6);

    // Converting the Stack into array
    Object[] arr = myStack.ToArray();

    // Displaying the elements in array
    foreach(Object i in arr)
    {
        Console.WriteLine(i);
    }
}

}
