範例

下列程式代碼範例示範如何使用 IpcChannel 來設定遠端伺服器及其用戶端。 此範例包含三個部分：

  • 伺服器

  • 用戶端

  • 伺服器和用戶端所使用的遠端物件。

下列程式代碼範例顯示伺服器。

備註

重要

使用不信任的資料呼叫此類別的方法，會造成安全性上的風險。 呼叫此類別的方法時，請一律使用信任的資料。 如需詳細資訊，請參閱 驗證所有輸入。

the.NET Framework 遠端基礎結構用來傳輸遠端呼叫的通道。 當用戶端呼叫遠端物件時，呼叫會串行化為用戶端通道所傳送並由伺服器通道接收的訊息。 收到訊息之後，就會還原串行化和處理訊息。 任何傳回的值會由伺服器通道傳輸，並由用戶端通道接收。

類別IpcChannel是結合 類別和 IpcServerChannel 類別功能的IpcClientChannel便利類別。

警告

在 自變數中將 exclusiveAddressUse 屬性設定為 false 時，可以針對相同的命名管道註冊數IpcServerChannel個properties物件。 在這種情況下，要求可以移至任何已註冊的通道。 只有在也使用 ALC 時，才會將此設定視為安全。

建構函式

IpcChannel()

初始化 IpcChannel 類別的新執行個體，只啟動用戶端通道，不啟動伺服器通道。
IpcChannel(IDictionary, IClientChannelSinkProvider, IServerChannelSinkProvider)

IpcChannel(IDictionary, IClientChannelSinkProvider, IServerChannelSinkProvider, CommonSecurityDescriptor)

IpcChannel(String)
