SendMessageChannelCache 建構函式

public:
 SendMessageChannelCache();

public SendMessageChannelCache();

Public Sub New ()

public:
 SendMessageChannelCache(System::ServiceModel::Activities::ChannelCacheSettings ^ factorySettings, System::ServiceModel::Activities::ChannelCacheSettings ^ channelSettings);

public SendMessageChannelCache(System.ServiceModel.Activities.ChannelCacheSettings factorySettings, System.ServiceModel.Activities.ChannelCacheSettings channelSettings);

new System.ServiceModel.Activities.SendMessageChannelCache : System.ServiceModel.Activities.ChannelCacheSettings * System.ServiceModel.Activities.ChannelCacheSettings -> System.ServiceModel.Activities.SendMessageChannelCache

Public Sub New (factorySettings As ChannelCacheSettings, channelSettings As ChannelCacheSettings)

參數

範例

以下範例展示了如何利用該 SendMessageChannelCache 類別在單一應用程式域中兩個工作流程應用程式間共享通道快取。

//sharing a channel cache between two workflow applications in a single app-domain.
sharedChannelCache = new SendMessageChannelCache(new ChannelCacheSettings { MaxItemsInCache = 5 }, new ChannelCacheSettings { MaxItemsInCache = 5 });

WorkflowApplication workflowApp1 = new WorkflowApplication(workflow);
workflowApp1.Completed = new Action<WorkflowApplicationCompletedEventArgs>(OnCompleted);
workflowApp1.Extensions.Add(sharedChannelCache);

WorkflowApplication workflowApp2 = new WorkflowApplication(workflow);
workflowApp2.Completed = new Action<WorkflowApplicationCompletedEventArgs>(OnCompleted);
workflowApp2.Extensions.Add(sharedChannelCache);

//disabling the channel cache so that channels are closed after being used.
SendMessageChannelCache disabledChannelCache = new SendMessageChannelCache(new ChannelCacheSettings { MaxItemsInCache = 0 }, new ChannelCacheSettings { MaxItemsInCache = 0 });

WorkflowApplication workflowApp3 = new WorkflowApplication(workflow);
workflowApp3.Completed = new Action<WorkflowApplicationCompletedEventArgs>(OnCompleted);
workflowApp3.Extensions.Add(disabledChannelCache);

備註

欲了解更多關於通道工廠的資訊，請參見 ChannelFactory 和 ChannelFactory<TChannel>。

你可以選擇只使用通道工廠快取，並透過將參數傳給 channelSettings 初始化為 ChannelCacheSettings 0 的建 MaxItemsInCache 構子來停用通道快取。 若要完全停用通道工廠快取與通道快取的快取，請將參數傳 factorySettings 入初始化為 ChannelCacheSettings 0 的建 MaxItemsInCache 構子。 請注意，如果頻道出廠快取被停用，你就無法開啟頻道快取。

public:
 SendMessageChannelCache(System::ServiceModel::Activities::ChannelCacheSettings ^ factorySettings, System::ServiceModel::Activities::ChannelCacheSettings ^ channelSettings, bool allowUnsafeCaching);

public SendMessageChannelCache(System.ServiceModel.Activities.ChannelCacheSettings factorySettings, System.ServiceModel.Activities.ChannelCacheSettings channelSettings, bool allowUnsafeCaching);

new System.ServiceModel.Activities.SendMessageChannelCache : System.ServiceModel.Activities.ChannelCacheSettings * System.ServiceModel.Activities.ChannelCacheSettings * bool -> System.ServiceModel.Activities.SendMessageChannelCache

Public Sub New (factorySettings As ChannelCacheSettings, channelSettings As ChannelCacheSettings, allowUnsafeCaching As Boolean)

參數

備註

預設情況下，快取只可用於 Send 未使用設定中定義端點的活動。 不過，如果你想開啟快取，請呼叫這個建構子，並將 allowUnsafeCaching 參數設為 true。 接下來，將這個類別的新實例新增為工作流程服務主機或工作流程實例的延伸模組。
