示例

以下代码示例演示了 Item[] 的用法。

// 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);

// Display the entry's properties, using the collection's Item
// accessor.
Console::WriteLine("collection[0].PermissionAccess: {0}",
    collection[0]->PermissionAccess);
Console::WriteLine("collection[0].MachineName: {0}",
    collection[0]->MachineName);
Console::WriteLine("collection[0].Label: {0}", collection[0]->Label);
Console::WriteLine("collection[0].Category: {0}",
    collection[0]->Category);

queue->Close();

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

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

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

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

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

// Display the entry's properties, using the collection's Item
// accessor.
Console.WriteLine("collection[0].PermissionAccess: {0}",
    collection[0].PermissionAccess);
Console.WriteLine("collection[0].MachineName: {0}",
    collection[0].MachineName);
Console.WriteLine("collection[0].Label: {0}", collection[0].Label);
Console.WriteLine("collection[0].Category: {0}",
    collection[0].Category.ToString());
