Examples

The following code example shows the behavior of the Copy method. This example is part of a larger example provided for the UIPermission class.

Note

The code example is intended to show the behavior of the method, not to demonstrate its use. In general, the methods of permission classes are used by the security infrastructure; they are not typically used in applications.

//Copy creates and returns an identical copy of the current permission.
void CopyDemo()
{
    Console::WriteLine("\n*************************  Copy() Demo *************************\n");

    UIPermission ^ uiPerm1 = gcnew UIPermission(UIPermissionWindow::SafeTopLevelWindows);
    UIPermission ^ uiPerm2 = gcnew UIPermission(PermissionState::None);
    uiPerm2 = (UIPermission ^)uiPerm1->Copy();
    if (uiPerm2 != nullptr)
        Console::WriteLine("The copy succeeded:  " + uiPerm2->ToString());
}

//Copy creates and returns an identical copy of the current permission.
private static void CopyDemo()
{

    UIPermission uiPerm1 = new UIPermission(UIPermissionWindow.SafeTopLevelWindows);
    UIPermission uiPerm2 = new UIPermission(PermissionState.None);
    uiPerm2 = (UIPermission)uiPerm1.Copy();
    if (uiPerm2 != null)
    {
        Console.WriteLine("The copy succeeded:  " + uiPerm2.ToString() + " \n");
    }
}

'Copy creates and returns an identical copy of the current permission.
Private Shared Sub CopyDemo()

    Dim uiPerm1 As New UIPermission(UIPermissionWindow.SafeTopLevelWindows)
    Dim uiPerm2 As New UIPermission(PermissionState.None)
    uiPerm2 = CType(uiPerm1.Copy(), UIPermission)
    If Not (uiPerm2 Is Nothing) Then
        Console.WriteLine("The copy succeeded:  " + uiPerm2.ToString() + " " + vbLf)
    End If

End Sub

Remarks

A copy of the permission represents the same access to resources as the original permission.
