BindingElement.CanBuildChannelListener<TChannel>(BindingContext) 方法

定义

命名空间:

System.ServiceModel.Channels

程序集:

System.ServiceModel.dll

返回一个值，该值指示绑定元素是否可以为特定类型的通道生成侦听器。

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

类型参数

TChannel

侦听器接受的通道类型。

参数

context

BindingContext

为绑定元素提供上下文的 BindingContext。

返回

Boolean

如果绑定元素可以生成类型为 true 的 IChannelListener<TChannel>，则为 IChannel；否则为 false。

例外

ArgumentNullException

context 为 null。

示例

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);

注解

如果要在生成侦听器之前检查是否可以为提供的 TChannel 生成 context 类型通道的通道侦听器，请使用此方法。 或者，通过调用 BuildChannelListener 来生成通道侦听器，并捕捉无法生成时所产生的异常。
