範例

以下程式碼範例示範如何利用介面 ILogicalThreadAffinative 將 主物件與身份物件 傳送至遠端地點以進行識別。 若要查看範例中使用的 HelloServiceClass 類別程式碼，請參閱該方法的範例 GetData 。 要查看本範例中使用的伺服器類別程式碼，請參閱該 RegisterActivatedServiceType 類別範例。 若要查看範例中使用的客戶端類別程式碼，請參閱該 CallContext 類別的範例。

備註

當遠端方法呼叫到另一個 AppDomain物件時，當前 CallContext 類別會 LogicalCallContext 產生一個，隨呼叫一同傳送到遠端位置。 只有暴露ILogicalThreadAffinative介面且儲存在 的CallContext物件才會被傳播到外部。AppDomain 不支援此介面的物件不會在 LogicalCallContext 有遠端方法呼叫的實例中傳送。
