IBindingDeliveryCapabilities 介面

定義

命名空間:

System.ServiceModel.Channels

組件:

System.ServiceModel.Primitives.dll

套件:

System.ServiceModel.Primitives v8.1.0

來源:

IBindingDeliveryCapabilities.cs

定義繫結必須實作的介面，以描述及通告用戶端和服務可能需要的功能。

public interface class IBindingDeliveryCapabilities

public interface IBindingDeliveryCapabilities

type IBindingDeliveryCapabilities = interface

Public Interface IBindingDeliveryCapabilities

範例

下列範例會要求 CalculatorService 必須使用 WSHttpBinding，並以排序的方式傳遞訊息。 在預設情況下，可靠的工作階段和佇列傳遞不會搭配這個繫結一起使用，但是可加以啟用。

<!-- Here is the configuration for a CalculatorService using a WSHttpBinding with ordered message delivery required. -->  
<?xml version="1.0" encoding="utf-8" ?>  
<configuration>  
   <system.serviceModel>  
      <services>  
         <service   
             type="Microsoft.ServiceModel.Samples.CalculatorService">  
            <!-- Use base address provided by host and a WSHttpBinding named "Binding1" -->  
            <endpoint address=""  
                      binding="wsHttpBinding"  
                      bindingConfiguration="Binding1"   
                      contract="Microsoft.ServiceModel.Samples.ICalculator" />  
         </service>  
      </services>  

      <bindings>  
         <wsHttpBinding>   
            <binding name="Binding1">           
               <!-- The next element enables a ReliableSession and required ordered delivery-->  
      <reliableSession enabled="true" ordered="true"/>  
      </binding>  
         </wsHttpBinding>  
      </bindings>  

   </system.serviceModel>  
</configuration>  

// The CalculatorService configuration has enabled a reliable session  
// with ordered delivery set to true. This means that the binding  
// requirement for ordered delivery specified by the  
// BindingRequirementsAttribute on the CalculatorService class  
// implemented below will be satisfied by this WSHttpBinding.  

using System;  
using System.ServiceModel;  

[ServiceContract]  
interface ICalculatorService  
{  
  [OperationBehavior()]  
  int Add(int a, int b);    

  [OperationContract]  
  int Subtract(int a, int b);  
}  

[BindingRequirements(  
  QueuedDeliveryRequirements=RequirementsMode.Disallow,  
  RequireOrderedDelivery=true  
)]  
class CalculatorService: ICalculatorService  
{  
  public int Add(int a, int b)  
  {  
    Console.WriteLine("Add called.");  
    return a + b;   
  }  

  public int Subtract(int a, int b)  
  {  
    Console.WriteLine("Subtract called.");  
    return a - b;  
  }  

  public int Multiply(int a, int b)  
  {  
    return a * b;  
  }  
}  

備註

如果用戶端和服務能夠在其合約中保證，它們所需的功能是由繫結所提供，則此繫結就必須實作 IBindingDeliveryCapabilities 介面。

屬性

AssuresOrderedDelivery	取得值，這個值指出繫結是否可以支援保證能夠以訊息傳送的順序來傳遞訊息。
QueuedDelivery	取得值，這個值指出繫結是否可以支援佇列訊息傳遞。
