OptionalReliableSession 类

  • 参考

定义

命名空间:
System.ServiceModel
程序集:
System.ServiceModel.Primitives.dll
程序集:
System.ServiceModel.dll

当使用预定义的绑定之一（该绑定是可选的）时，提供对是否启用可靠会话的便捷访问。

public ref class OptionalReliableSession : System::ServiceModel::ReliableSession
public class OptionalReliableSession : System.ServiceModel.ReliableSession
type OptionalReliableSession = class
    inherit ReliableSession
Public Class OptionalReliableSession
Inherits ReliableSession
继承
Object
ReliableSession
OptionalReliableSession

示例

下面的代码演示如何创建新的可靠会话，以及访问和更改该会话的默认值。

private void Run()
{
    WSHttpBinding b = new WSHttpBinding();
    b.Name = "HttpOrderedReliableSessionBinding";

    // Get a reference to the OptionalreliableSession object of the
    // binding and set its properties to new values.
    OptionalReliableSession myReliableSession = b.ReliableSession;
    myReliableSession.Enabled = true; // The default is false.
    myReliableSession.Ordered = false; // The default is true.
    myReliableSession.InactivityTimeout =
        new TimeSpan(0, 15, 0); // The default is 10 minutes.
    // Create a URI for the service's base address.
    Uri baseAddress = new Uri("http://localhost:8008/Calculator");

    // Create a service host.
    ServiceHost sh = new ServiceHost(typeof(Calculator), baseAddress);

    // Optional: Print out the binding information.
    PrintBindingInfo(b);
    // Create a URI for an endpoint, then add a service endpoint using the
    // binding with the latered OptionalReliableSession settings.
    sh.AddServiceEndpoint(typeof(ICalculator), b, "ReliableCalculator");
    sh.Open();

    Console.WriteLine("Listening...");
    Console.ReadLine();
    sh.Close();
}

private void PrintBindingInfo(WSHttpBinding b)
{
    Console.WriteLine(b.Name);
    Console.WriteLine("Enabled: {0}", b.ReliableSession.Enabled);
    Console.WriteLine("Ordered: {0}", b.ReliableSession.Ordered);
    Console.WriteLine("Inactivity in Minutes: {0}",
        b.ReliableSession.InactivityTimeout.TotalMinutes);
}

Private Sub Run()
    Dim b As New WSHttpBinding()
    b.Name = "HttpOrderedReliableSessionBinding"

    ' Get a reference to the OptionalreliableSession object of the 
    ' binding and set its properties to new values.
    Dim myReliableSession As OptionalReliableSession = b.ReliableSession
    myReliableSession.Enabled = True ' The default is false.
    myReliableSession.Ordered = False ' The default is true. 
    myReliableSession.InactivityTimeout = New TimeSpan(0, 15, 0)
    ' The default is 10 minutes.
    ' Create a URI for the service's base address.
    Dim baseAddress As New Uri("http://localhost:8008/Calculator")

    ' Create a service host.
    Dim sh As New ServiceHost(GetType(Calculator), baseAddress)

    ' Optional: Print out the binding information. 
    PrintBindingInfo(b)
    ' Create a URI for an endpoint, then add a service endpoint using the
    ' binding with the latered OptionalReliableSession settings.
    sh.AddServiceEndpoint(GetType(ICalculator), b, "ReliableCalculator")
    sh.Open()

    Console.WriteLine("Listening...")
    Console.ReadLine()
    sh.Close()
End Sub

Private Sub PrintBindingInfo(ByVal b As WSHttpBinding)
    Console.WriteLine(b.Name)
    Console.WriteLine("Enabled: {0}", b.ReliableSession.Enabled)
    Console.WriteLine("Ordered: {0}", b.ReliableSession.Ordered)
    Console.WriteLine("Inactivity in Minutes: {0}", b.ReliableSession.InactivityTimeout.TotalMinutes)

End Sub

注解

通过使用三种由系统提供的绑定来实现启用可靠会话。 可靠会话为：

构造函数

OptionalReliableSession()

初始化 OptionalReliableSession 类的新实例。
OptionalReliableSession(ReliableSessionBindingElement)

从可靠会话绑定元素中初始化 OptionalReliableSession 类的新实例。

属性

Enabled

获取或设置一个值，该值指示是否已启用可靠会话。
InactivityTimeout

获取或设置服务在关闭之前保持非活动状态的时间间隔。

(继承自 ReliableSession)
Ordered

获取或设置一个值，该值指示消息传递是否必须保持与消息发送一致的顺序。

(继承自 ReliableSession)

方法

Equals(Object)

确定指定对象是否等于当前对象。

(继承自 Object)
GetHashCode()

作为默认哈希函数。

(继承自 Object)
GetType()

获取当前实例的 Type。

(继承自 Object)
MemberwiseClone()

创建当前 Object 的浅表副本。

(继承自 Object)
ToString()

返回表示当前对象的字符串。

(继承自 Object)
