ChannelDispatcher.ReceiveSynchronously 属性

定义

命名空间:

System.ServiceModel.Dispatcher

程序集:

System.ServiceModel.dll

获取或设置一个值，该值指定调度程序是否使用同步调用从通道读取消息。

public:
 property bool ReceiveSynchronously { bool get(); void set(bool value); };

public bool ReceiveSynchronously { get; set; }

member this.ReceiveSynchronously : bool with get, set

Public Property ReceiveSynchronously As Boolean

属性值

Boolean

如果调度程序使用同步方法从通道读取消息，则为 true，否则为 false。 默认值为 false。

例外

InvalidOperationException

通信对象处于 Opening 或 Opened 状态。

ObjectDisposedException

通信对象处于 Closing 或 Closed 状态。

CommunicationObjectFaultedException

通信对象处于 Faulted 状态。

示例

Uri baseAddress = new Uri("http://localhost:8001/Simple");
ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService), baseAddress);

serviceHost.AddServiceEndpoint(
    typeof(ICalculator),
    new WSHttpBinding(),
    "CalculatorServiceObject");

serviceHost.Open();

IChannelListener icl = serviceHost.ChannelDispatchers[0].Listener;
ChannelDispatcher dispatcher = new ChannelDispatcher(icl);
bool receiveSynchronously = dispatcher.ReceiveSynchronously;

Dim baseAddress As New Uri("http://localhost:8001/Simple")
Dim serviceHost As New ServiceHost(GetType(CalculatorService), baseAddress)

serviceHost.AddServiceEndpoint(GetType(ICalculator), New WSHttpBinding(), "CalculatorServiceObject")

serviceHost.Open()

Dim icl As IChannelListener = serviceHost.ChannelDispatchers(0).Listener
Dim dispatcher As New ChannelDispatcher(icl)
Dim receiveSynchronously As Boolean = dispatcher.ReceiveSynchronously

注解

如果绑定实现 IBindingRuntimePreferences，则 Windows Communication Foundation (WCF) 将 属性的值 ReceiveSynchronously 分配给此属性。 因此，如果此值为 true，则重写 false 的 ReceiveSynchronously 默认值。

只有当 ChannelDispatcher 的实例处于 Created 状态时才可以设置此属性，因为该状态是唯一一个可变且不被释放的状态。
