36.6.5Получение индекса элемента
Метод Contains() используется для проверки того, содержится ли заданный элемент в коллекции. Если известно, что элемент в коллекции есть, метод IndexOf интерфейса IList позволяет получить его индекс:
int IndexOf(Object^ value);
Если элемент со значением value найден в коллекции, метод возвращает его индекс, а в противном случае он возвращает -1. Пример реализации этого метода:
using namespace System;
using namespace System::Collections;
public ref class CObjects : public IList
{
private:
Int items;
array<Object ^> ^ objects;
public:
. . . No Change
virtual int IndexOf(Object ^);
};
. . . No Change
int CObjects::IndexOf(Object ^ value)
{
for(int i = 0; i < Count; i++
if( objects[i] == value ) return i;
return -1;
}
Метод IndexOf() вызывает метод Equals() класса объектов, которые составляют коллекцию. Если имеющаяся реализация метода Equals() не подходит для объектов коллекции, вы должны сделать свою реализацию этого метода.
36.6.6Упражнение: получение индекса элемента
Open the Properties.cpp source file. In the Functions combo box, select IndexOf and implement the method as follows:
// This method is used to check whether the item passed as
// argument exists in the collection. If so, it returns its index
int CProperties::IndexOf(Object ^ value)
{
int custIndex = -1;
for(int i = 0; i < Count; i++)
{
if( dynamic_cast<CRentalProperty ^>
(this[i])->Equals(dynamic_cast<CRentalProperty ^>(value)) )
{
custIndex = i;
break;
}
}
return custIndex;
}
Open the Exercise.cpp source file and make the following changes:
#include "RentalProperty.h"
#include "Properties.h"
using namespace System;
Int main()
{
. . . No Change
Console::WriteLine(L"8--8--8--8--8--8--8--8--8--8--8--8--8--8--8");
CRentalProperty ^ item3 = gcnew CRentalProperty;
item3->PropertyCode = 224006;
item3->PropertyType = PropertyTypes::Apartment;
item3->PropertyCondition = PropertyConditions::Excellent;
item3->Bedrooms = 2;
item3->Bathrooms = 1;
item3->MonthlyRent = 1250.55;
Console::WriteLine(L"-=- Sample Property -=-");
Console::WriteLine(L"Property #: {0}", item3->PropertyCode);
Console::WriteLine(L"Property Type: {0}",item3->PropertyType);
Console::WriteLine(L"Condition: {0}", item3->PropertyCondition);
Console::WriteLine(L"Bedrooms: {0}", item3->Bedrooms);
Console::WriteLine(L"Bathrooms: {0}", item3->Bathrooms);
Console::WriteLine(L"Monthly Rent: {0}",item3->MonthlyRent);
Console::WriteLine(L"The index of this property is: {0}",
properties->IndexOf(item3));
Console::WriteLine(L"8--8--8--8--8--8--8--8--8--8--8--8--8--8");
return 0;
}
