The following code example gets and sets the value of a message queue's EnableConnectionCache property.

// Set the MessageQueue.EnableConnectionCache property value.
MessageQueue.EnableConnectionCache = false;

// Display the new value of the MessageQueue.EnableConnectionCache
// property.
Console.WriteLine("MessageQueue.EnableConnectionCache: {0}",
    MessageQueue.EnableConnectionCache);

A connection cache is a list of references to structures that contain read or write handles to queues. When EnableConnectionCache is true, the MessageQueue borrows handles from the cache each time you call Send(Object), Peek, or Receive, rather than open new handles. This can improve performance. Using a connection cache also insulates the MessageQueue from changes in the network topology.

If you create a new connection to a queue when the connection cache is full, the MessageQueue overwrites the least recently accessed structure with the new connection. You can clear the cache entirely by calling ClearConnectionCache, for example, if the format names of the queues you are working with have changed so that the previous read and write handles are no longer valid.
