Copies the Stack to a new array.
public:
virtual cli::array <System::Object ^> ^ ToArray();
public virtual object[] ToArray ();
public virtual object?[] ToArray ();
abstract member ToArray : unit -> obj[]
override this.ToArray : unit -> obj[]
Public Overridable Function ToArray () As Object()
A new array containing copies of the elements of the Stack.
The following example shows how to copy a Stack into a one-dimensional array.
using namespace System;
using namespace System::Collections;
void PrintValues( Array^ myArr, char mySeparator );
int main()
{
// Creates and initializes the source Stack.
Stack^ mySourceQ = gcnew 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( String::typeid, 15 );
myTargetArray->SetValue( "The", 0 );
myTargetArray->SetValue( "quick", 1 );
myTargetArray->SetValue( "brown", 2 );
myTargetArray->SetValue( "fox", 3 );
myTargetArray->SetValue( "jumps", 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.
array<Object^>^myStandardArray = mySourceQ->ToArray();
// Displays the values of the new standard array.
Console::WriteLine( "The new standard array contains the following:" );
PrintValues( myStandardArray, ' ' );
}
void PrintValues( Array^ myArr, char mySeparator )
{
IEnumerator^ myEnum = myArr->GetEnumerator();
while ( myEnum->MoveNext() )
{
Object^ myObj = safe_cast<Object^>(myEnum->Current);
Console::Write( "{0}{1}", mySeparator, myObj );
}
Console::WriteLine();
}

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.
