En ny matris som innehåller kopior av elementen i Stack.
Exempel
I följande exempel visas hur du kopierar en Stack till en endimensionell matris.
using System;
using System.Collections;

public static void Main() {
// Creates and initializes the source Stack.
Stack mySourceQ = new Stack();
mySourceQ.Push( "barn" );

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( "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, ' ' );

Kommentarer
Elementen kopieras till matrisen i LIFO-ordning (last-in-first-out), ungefär som ordningen på de element som returneras av en följd av anrop till Pop.
Den här metoden är en O(n) åtgärd, där n är Count.
