示例

下面的代码示例删除消息队列队列(如果存在)。

#using <system.dll>
#using <system.messaging.dll>

using namespace System;
using namespace System::Messaging;
int main()
{
   
   // Determine whether the queue exists.
   if ( MessageQueue::Exists( ".\\myQueue" ) )
   {
      try
      {
         
         // Delete the queue.
         MessageQueue::Delete( ".\\myQueue" );
      }
      catch ( MessageQueueException^ e ) 
      {
         if ( e->MessageQueueErrorCode == MessageQueueErrorCode::AccessDenied )
         {
            Console::WriteLine( "Access is denied. Queue might be a system queue." );
         }
         
         // Handle other sources of MessageQueueException.
      }

   }

   return 0;

注解

参数的 path 语法取决于队列的类型。

队列类型 语法
公共队列 MachineName\QueueName
专用队列 MachineName\Private$\QueueName

有关更多语法,请参阅 Path 属性。

或者,可以使用 FormatNameLabel 来描述队列路径。

参考 语法
格式名 FormatName:[ format name ]
