static member Create : string * bool -> System.Messaging.MessageQueue
Public Shared Function Create (path As String, transactional As Boolean) As MessageQueue

参数

path
String

要创建的队列的路径。

transactional
Boolean

如果创建事务性队列,为 true;如果创建非事务性队列,则为 false

返回

若要在应用程序中创建 类的新实例 MessageQueue 并将其绑定到现有队列,请使用 MessageQueue 构造函数。 若要在消息队列中创建新队列,请调用 Create(String)

参数的 path 语法取决于它引用的队列类型,如下表所示。
