Stack.CopyTo Method

Copies the Stack to an existing one-dimensional Array, starting at the specified array index.

Namespace: System.Collections
Assembly: mscorlib (in mscorlib.dll)

public virtual void CopyTo (
	Array array,
	int index
)
public void CopyTo (
	Array array, 
	int index
)
public function CopyTo (
	array : Array, 
	index : int
)
Not applicable.

Parameters

array

The one-dimensional Array that is the destination of the elements copied from Stack. The Array must have zero-based indexing.

index

The zero-based index in array at which copying begins.

Exception typeCondition

ArgumentNullException

array is a null reference (Nothing in Visual Basic).

ArgumentOutOfRangeException

index is less than zero.

ArgumentException

array is multidimensional.

-or-

index is equal to or greater than the length of array.

-or-

The number of elements in the source Stack is greater than the available space from index to the end of the destination array.

InvalidCastException

The type of the source Stack cannot be cast automatically to the type of the destination 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.

The following example shows how to copy a Stack into a one-dimensional array.

using System;
using System.Collections;
public class SamplesStack  {

   public static void Main()  {

      // Creates and initializes the source Stack.
      Stack mySourceQ = new Stack();
      mySourceQ.Push( "barn" );
      mySourceQ.Push( "the" );
      mySourceQ.Push( "in" );
      mySourceQ.Push( "cats" );
      mySourceQ.Push( "napping" );
      mySourceQ.Push( "three" );

      // Creates and initializes the one-dimensional target Array.
      Array myTargetArray=Array.CreateInstance( typeof(String), 15 );
      myTargetArray.SetValue( "The", 0 );
      myTargetArray.SetValue( "quick", 1 );
      myTargetArray.SetValue( "brown", 2 );
      myTargetArray.SetValue( "fox", 3 );
      myTargetArray.SetValue( "jumped", 4 );
      myTargetArray.SetValue( "over", 5 );
      myTargetArray.SetValue( "the", 6 );
      myTargetArray.SetValue( "lazy", 7 );
      myTargetArray.SetValue( "dog", 8 );

      // Displays the values of the target Array.
      Console.WriteLine( "The target Array contains the following (before and after copying):" );
      PrintValues( myTargetArray, ' ' );

      // Copies the entire source Stack to the target Array, starting at index 6.
      mySourceQ.CopyTo( myTargetArray, 6 );

      // Displays the values of the target Array.
      PrintValues( myTargetArray, ' ' );

      // Copies the entire source Stack to a new standard array.
      Object[] myStandardArray = mySourceQ.ToArray();

      // Displays the values of the new standard array.
      Console.WriteLine( "The new standard array contains the following:" );
      PrintValues( myStandardArray, ' ' );

   }


   public static void PrintValues( Array myArr, char mySeparator )  {
      foreach ( Object myObj in myArr )  {
         Console.Write( "{0}{1}", mySeparator, myObj );
      }
      Console.WriteLine();
   }

}
