回傳一個值，表示綁定元件是否能為特定通道建立監聽器。
public:
generic <typename TChannel>
where TChannel : class, System::ServiceModel::Channels::IChannel virtual bool CanBuildChannelListener(System::ServiceModel::Channels::BindingContext ^ context);public virtual bool CanBuildChannelListener<TChannel>(System.ServiceModel.Channels.BindingContext context) where TChannel : class, System.ServiceModel.Channels.IChannel;abstract member CanBuildChannelListener : System.ServiceModel.Channels.BindingContext -> bool (requires 'Channel : null and 'Channel :> System.ServiceModel.Channels.IChannel)
override this.CanBuildChannelListener : System.ServiceModel.Channels.BindingContext -> bool (requires 'Channel : null and 'Channel :> System.ServiceModel.Channels.IChannel)Public Overridable Function CanBuildChannelListener(Of TChannel As {Class, IChannel}) (context As BindingContext) As Boolean類型參數
- TChannel
聽眾接受的頻道類型。
參數
- context
- BindingContext
BindingContext那就為綁定元素提供了背景。
傳回
true若 型IChannelListener<TChannel>IChannel態可由綁定元素構成;否則， false。
例外狀況
context 是 null。
範例
CustomBinding binding = new CustomBinding();
HttpTransportBindingElement element = new HttpTransportBindingElement();
BindingParameterCollection parameters = new BindingParameterCollection();
Uri baseAddress = new Uri("http://localhost:8000/ChannelApp");
String relAddress = "http://localhost:8000/ChannelApp/service";
BindingContext context = new BindingContext(binding, parameters, baseAddress, relAddress, ListenUriMode.Explicit);
bool bFlag = element.CanBuildChannelListener<IReplyChannel>(context);
備註
如果你想先確認能為某類型的 TChannel 頻道建立 context 頻道監聽器，再嘗試建立監聽器，請使用此方法。 或者，透過呼叫 BuildChannelListener 來建立通道監聽器，若無法建立例外，則捕捉該異常。
