ServiceHostFactory 类

定义

命名空间:

System.ServiceModel.Activation

程序集:

System.ServiceModel.dll

程序集:

System.ServiceModel.Activation.dll

在托管宿主环境中提供 ServiceHost 的实例的工厂，在此环境中为响应传入消息而动态创建宿主实例。

public ref class ServiceHostFactory : System::ServiceModel::Activation::ServiceHostFactoryBase

public class ServiceHostFactory : System.ServiceModel.Activation.ServiceHostFactoryBase

type ServiceHostFactory = class
    inherit ServiceHostFactoryBase

Public Class ServiceHostFactory
Inherits ServiceHostFactoryBase

继承

Object

ServiceHostFactoryBase

ServiceHostFactory

派生

System.Data.Services.DataServiceHostFactory

System.ServiceModel.Activation.WebScriptServiceHostFactory

System.ServiceModel.Activation.WebServiceHostFactory

System.Web.ApplicationServices.ApplicationServicesHostFactory

示例

下面的示例演示如何使用 ServiceHostFactory 类：

public class DerivedFactory : ServiceHostFactory
{

    protected override ServiceHost CreateServiceHost( Type t, Uri[] baseAddresses )
    {
        return new DerivedHost( t, baseAddresses );
    }

    //Then in the CreateServiceHost method, we can do all of the
    //things that we can do in a self-hosted case:
    public override ServiceHostBase CreateServiceHost
            (string service, Uri[] baseAddresses)

    {

        // The service parameter is ignored here because we know our service.
        ServiceHost serviceHost = new ServiceHost(typeof(HelloService),
            baseAddresses);
        return serviceHost;
    }
}

Public Class DerivedFactory
    Inherits ServiceHostFactory

    Protected Overrides Overloads Function CreateServiceHost(ByVal t As Type, ByVal baseAddresses() As Uri) As ServiceHost
        Return New DerivedHost(t, baseAddresses)
    End Function

    'Then in the CreateServiceHost method, we can do all of the
    'things that we can do in a self-hosted case:
    Public Overrides Overloads Function CreateServiceHost(ByVal service As String, ByVal baseAddresses() As Uri) As ServiceHostBase


        ' The service parameter is ignored here because we know our service.
        Dim serviceHost As New ServiceHost(GetType(HelloService), baseAddresses)
        Return serviceHost

    End Function

End Class

注解

支持动态激活的托管宿主环境包括 Internet 信息服务 (IIS) 和 Windows 进程激活服务 (WAS)。

如果已实现 ServiceHost 的自定义派生，还应考虑实现派生自 ServiceHostFactory 类的工厂。

如果已实现 ServiceHostBase 的自定义派生，还应考虑实现可直接从 ServiceHostFactoryBase 派生工厂的工厂。

构造函数

ServiceHostFactory()

初始化 ServiceHostFactory 类的新实例。

方法

CreateServiceHost(String, Uri[])	创建具有特定基址的 ServiceHost，并使用指定数据对其进行初始化。
CreateServiceHost(Type, Uri[])	为具有特定基址的指定类型的服务创建 ServiceHost。
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)
