This program shows how to pass an array of managed objects and how to return an array of managed objects.

Example 1:

using namespace System;

public ref class CSquare
{
private:
    double sd;

public:
    CSquare() : sd(0.00) {}
    CSquare(double side) : sd(side) { }
    ~CSquare() { }

    property double Side
    {
	double get() { return sd; }
	void set(double s)
	{
	    if( s <= 0 )
		sd = 0.00;
	    else
		sd = s;
	}
    }

    property double Perimeter { double get() { return sd * 4; } }
    property double Area { double get() { return sd * sd; } }
};

array<CSquare ^> ^ CreateSquares()
{
    array<CSquare ^> ^ sqrs = gcnew array<CSquare ^>(5);

    sqrs[0] = gcnew CSquare;
    sqrs[0]->Side = 5.62;
    sqrs[1] = gcnew CSquare;
    sqrs[1]->Side = 770.448;
    sqrs[2] = gcnew CSquare;
    sqrs[2]->Side = 2442.08;
    sqrs[3] = gcnew CSquare;
    sqrs[3]->Side = 82.304;
    sqrs[4] = gcnew CSquare;
    sqrs[4]->Side = 640.1115;

    return sqrs;
}

void DisplaySquares(array<CSquare ^> ^ squares)
{
    Console::WriteLine(L"Squares Characteristics");
    Console::WriteLine(L"Square 1");
    Console::WriteLine(L"Side:      {0}", squares[0]->Side);
    Console::WriteLine(L"Perimeter: {0}", squares[0]->Perimeter);
    Console::WriteLine(L"Area:      {0}\n", squares[0]->Area);

    Console::WriteLine(L"Square 2");
    Console::WriteLine(L"Side:      {0}", squares[1]->Side);
    Console::WriteLine(L"Perimeter: {0}", squares[1]->Perimeter);
    Console::WriteLine(L"Area:      {0}\n", squares[1]->Area);

    Console::WriteLine(L"Side:      {0}", squares[3]->Side);
    Console::WriteLine(L"Perimeter: {0}", squares[3]->Perimeter);
    Console::WriteLine(L"Area:      {0}\n", squares[3]->Area);

    Console::WriteLine(L"Square 5");
    Console::WriteLine(L"Side:      {0}", squares[4]->Side);
    Console::WriteLine(L"Perimeter: {0}", squares[4]->Perimeter);
    Console::WriteLine(L"Area:      {0}\n", squares[4]->Area);
}

int main()
{
    array<CSquare ^> ^ squares = CreateSquares();
    DisplaySquares(squares);

    Console::WriteLine();
    return 0;
}
