名稱	Description
ICommunicationObject.BeginOpen(AsyncCallback, Object)	開始異步操作以開啟通訊物件。
ICommunicationObject.BeginOpen(TimeSpan, AsyncCallback, Object)	開始異步操作，以在指定的時間間隔內開啟通訊物件。

ICommunicationObject.BeginOpen(AsyncCallback, Object)

開始異步操作以開啟通訊物件。

 virtual IAsyncResult ^ System.ServiceModel.ICommunicationObject.BeginOpen(AsyncCallback ^ callback, System::Object ^ state) = System::ServiceModel::ICommunicationObject::BeginOpen;

IAsyncResult ICommunicationObject.BeginOpen(AsyncCallback callback, object state);

abstract member System.ServiceModel.ICommunicationObject.BeginOpen : AsyncCallback * obj -> IAsyncResult
override this.System.ServiceModel.ICommunicationObject.BeginOpen : AsyncCallback * obj -> IAsyncResult

Function BeginOpen (callback As AsyncCallback, state As Object) As IAsyncResult Implements ICommunicationObject.BeginOpen

參數

callback

AsyncCallback

AsyncCallback接收非同步開啟操作完成通知的代理。

state

Object

由應用程式指定的物件，包含與非同步開啟操作相關的狀態資訊。

傳回

IAsyncResult

那 IAsyncResult 個指的是非同步開啟操作。

實作

BeginOpen(AsyncCallback, Object)

ICommunicationObject.BeginOpen(TimeSpan, AsyncCallback, Object)

開始異步操作，以在指定的時間間隔內開啟通訊物件。

 virtual IAsyncResult ^ System.ServiceModel.ICommunicationObject.BeginOpen(TimeSpan timeout, AsyncCallback ^ callback, System::Object ^ state) = System::ServiceModel::ICommunicationObject::BeginOpen;

IAsyncResult ICommunicationObject.BeginOpen(TimeSpan timeout, AsyncCallback callback, object state);

abstract member System.ServiceModel.ICommunicationObject.BeginOpen : TimeSpan * AsyncCallback * obj -> IAsyncResult
override this.System.ServiceModel.ICommunicationObject.BeginOpen : TimeSpan * AsyncCallback * obj -> IAsyncResult

Function BeginOpen (timeout As TimeSpan, callback As AsyncCallback, state As Object) As IAsyncResult Implements ICommunicationObject.BeginOpen

參數

timeout

TimeSpan

那 TimeSpan 是指定傳送操作完成多久才會逾時。

callback

AsyncCallback

AsyncCallback接收非同步開啟操作完成通知的代理。

state

Object

由應用程式指定的物件，包含與非同步開啟操作相關的狀態資訊。

傳回

IAsyncResult

那 IAsyncResult 個指的是非同步開啟操作。

實作

BeginOpen(TimeSpan, AsyncCallback, Object)
