注解
使用此重载创建非事务性消息队列队列。
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。
队列类型 | 语法 |
---|---|
公共队列 | MachineName \QueueName |
专用队列 | MachineName \Private$ \QueueName |

注解
可以使用此重载在消息队列中创建事务队列。 可以通过将 参数设置为 transactional
false
或调用 的另一个重载 Create(String)来创建非事务性队列。
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)。
