// Connect to a queue on the local computer.
MessageQueue^ queue = gcnew MessageQueue(".\\exampleQueue");

// Create a new instance of MessageQueuePermission.
MessageQueuePermission^ permission = gcnew MessageQueuePermission();

// Get an instance of MessageQueuePermissionEntryCollection from the
// permission's PermissionEntries property.
MessageQueuePermissionEntryCollection^ collection =
    permission->PermissionEntries;

// Create a new instance of MessageQueuePermissionEntry.
MessageQueuePermissionEntry^ entry = gcnew MessageQueuePermissionEntry(
    MessageQueuePermissionAccess::Receive, 
    queue->MachineName, 
    queue->Label, 
    queue->Category.ToString());

// Add the entry to the collection.
collection->Add(entry);

// Create an array of type MessageQueuePermissionEntry.
array<MessageQueuePermissionEntry^>^ entries = 
    gcnew array<MessageQueuePermissionEntry^>(1);

// Copy the collection to index 0 of the array.
collection->CopyTo(entries, 0);

// Show that the array now contains the entry.
Console::WriteLine("entries[0].PermissionAccess: {0}",
