OneWayBindingElement.CanBuildChannelListener<TChannel>(BindingContext) 方法
定义
获取一个值,该值指示是否可以生成指定类型的通道侦听器。Gets a value that indicates whether a channel listener of the specified type can be built.
public:
generic <typename TChannel>
where TChannel : class, System::ServiceModel::Channels::IChannel override bool CanBuildChannelListener(System::ServiceModel::Channels::BindingContext ^ context);
public override bool CanBuildChannelListener<TChannel> (System.ServiceModel.Channels.BindingContext context) where TChannel : class, System.ServiceModel.Channels.IChannel;
override this.CanBuildChannelListener : System.ServiceModel.Channels.BindingContext -> bool (requires 'Channel : null and 'Channel :> System.ServiceModel.Channels.IChannel)
Public Overrides Function CanBuildChannelListener(Of TChannel As {Class, IChannel}) (context As BindingContext) As Boolean
类型参数
- TChannel
要生成的通道侦听器的类型。The type of channel listener to build.
参数
- context
- BindingContext
为绑定元素提供上下文的 BindingContext。The BindingContext that provides context for the binding element.
返回
如果可以生成指定类型的通道侦听器,则为 true;否则为 false。true if a channel listener of the specified type can be built; otherwise, false. 默认为 false。The default is false.
例外
context 为 null。context is null.
注解
在尝试创建通道侦听器之前应调用此方法。You should call this method before trying to create a channel listener.
true 是 TChannel,并且绑定堆栈中当前绑定的下一个绑定是 IInputChannel 或 IDuplexSessionChannel 时,此方法将返回 IReplyChannel。This method returns true when TChannel is an IInputChannel, and the binding below the present one in the binding stack is an IDuplexSessionChannel or IReplyChannel.
