Örnekler

Aşağıdaki kod örneği yönteminin Intersect davranışını gösterir. Bu örnek, sınıfı için UIPermission sağlanan daha büyük bir örneğin parçasıdır.

// Intersect creates and returns a new permission that is the intersection of the
// current permission and the permission specified.
void IntersectDemo()
{
    Console::WriteLine("\n**********************  Intersect() Demo ***********************\n");

    UIPermission ^ uiPerm2 = gcnew UIPermission(UIPermissionWindow::SafeSubWindows,UIPermissionClipboard::NoClipboard);
    UIPermission ^ p3 = (UIPermission^)uiPerm1->Intersect(uiPerm2);

        Console::WriteLine("   The intersection of {0} and \n\t{1} = {2} ", uiPerm1->Window,
                               uiPerm1->Window, (nullptr != p3)?p3->Window.ToString():"null");

Açıklamalar

İki iznin kesişimi, her ikisinin de ortak olarak açıkladıkları işlem kümesini açıklayan bir izindir. Özellikle, geçerli izindeki ve belirtilen izindekilerin UIPermissionWindow ve UIPermissionClipboard değerlerinin en az izin veren değerlerini temsil eder.
