ServiceHostBase 类

定义

public ref class ServiceHostBase abstract : System::ServiceModel::Channels::CommunicationObject, IDisposable, System::ServiceModel::IExtensibleObject<System::ServiceModel::ServiceHostBase ^>

public abstract class ServiceHostBase : System.ServiceModel.Channels.CommunicationObject, IDisposable, System.ServiceModel.IExtensibleObject<System.ServiceModel.ServiceHostBase>

type ServiceHostBase = class
    inherit CommunicationObject
    interface IExtensibleObject<ServiceHostBase>
    interface IDisposable

Public MustInherit Class ServiceHostBase
Inherits CommunicationObject
Implements IDisposable, IExtensibleObject(Of ServiceHostBase)

继承

Object

CommunicationObject

ServiceHostBase

派生

System.ServiceModel.Activities.WorkflowServiceHost

System.ServiceModel.ServiceHost

实现

IDisposable IExtensibleObject<ServiceHostBase>

示例

此示例使用派生自ServiceHost的ServiceHostBase类。

// Host the service within this EXE console application.
public static void Main()
{
  using (ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService)))
  {
    try
    {
      // Open the ServiceHost to start listening for messages.
      serviceHost.Open();

        // The service can now be accessed.
      Console.WriteLine("The service is ready.");
      Console.WriteLine("Press <ENTER> to terminate service.");
      Console.ReadLine();

      // Close the ServiceHost.
      serviceHost.Close();
    }
    catch (TimeoutException timeProblem)
    {
      Console.WriteLine(timeProblem.Message);
      Console.ReadLine();
    }
    catch (CommunicationException commProblem)
    {
      Console.WriteLine(commProblem.Message);
      Console.ReadLine();
    }
  }
}

' Host the service within this EXE console application.
Public Shared Sub Main()
    ' Create a ServiceHost for the CalculatorService type and use the base address from config.
    Using svcHost As New ServiceHost(GetType(CalculatorService))
        Try
            ' Open the ServiceHost to start listening for messages.
            svcHost.Open()

            ' The service can now be accessed.
            Console.WriteLine("The service is ready.")
            Console.WriteLine("Press <ENTER> to terminate service.")
            Console.WriteLine()
            Console.ReadLine()

            'Close the ServiceHost.
            svcHost.Close()

        Catch timeout As TimeoutException
            Console.WriteLine(timeout.Message)
            Console.ReadLine()
        Catch commException As CommunicationException
            Console.WriteLine(commException.Message)
            Console.ReadLine()
        End Try
    End Using

End Sub

注解

使用该 ServiceHostBase 类创建提供自定义编程模型的主机。 Windows Communication Foundation （WCF） 服务编程模型使用 ServiceHost 类。

对于派生自此类的托管 C++ 用户的特殊说明：

• 将清理代码置于 （On）（Begin）Close（and/或 OnAbort），而不是析构函数中。
• 避免析构函数;它们会导致编译器自动生成 IDisposable。
• 避免非引用成员;它们可能会导致编译器自动生成 IDisposable。
• 避免终结器;但是，如果包含一个，则应禁止生成警告和调用 SuppressFinalize(Object) 以及终结器本身从 （On）（Begin）Close （和/或 OnAbort） 模拟自动生成 IDisposable 的行为。
