多的网络服务，从而多单

Question

好大家好

我有一个项目，倍数Web服务，所以我创造了性能的各种单例类的想法。现在我想创建一个单独的类，并且有我的web服务

例如

public static WebServiceMaster 
{ 
    internal ServiceX WebX; 
    internal ServiceY WebY; 
    ...... 
    public static WEbServiceMaster GetInstance() 
    ..... 
} 

什么想想的实例？ 是那么糟糕？

好了，终于做到这一点。我知道这是不完美的

Public NotInheritable Class ServiceProxySingleton 

Private _services As IDictionary(Of ProxyServicesEnum, IServiceDispatcher) = New Dictionary(Of ProxyServicesEnum, IServiceDispatcher) 
Private _dbRepository As IDACommon 

Private Sub New() 
    _dbRepository = New DACommon() 
    LoadServices() 
End Sub 

Private Sub LoadServices() 
    _services.Add(ProxyServicesEnum.eActivity, New ActivityServiceImp(_dbRepository)) 
    _services.Add(ProxyServicesEnum.eAvailability, New AvailabilityServiceImp(_dbRepository)) 
    _services.Add(ProxyServicesEnum.eBrochure, New BrochureServiceImp(_dbRepository)) 
    _services.Add(ProxyServicesEnum.eInformation, New InformationServiceImp(_dbRepository)) 
    _services.Add(ProxyServicesEnum.eMeetingRoom, New MeetingRoomServiceImp(_dbRepository)) 
    _services.Add(ProxyServicesEnum.eMembership, New MembershipServiceImp(_dbRepository)) 
    _services.Add(ProxyServicesEnum.eName, New NameServiceImp(_dbRepository)) 
    _services.Add(ProxyServicesEnum.eReservation, New ReservationServiceImp(_dbRepository)) 
    _services.Add(ProxyServicesEnum.eResvAdvanced, New ResvAdvancedServiceImp(_dbRepository)) 
    _services.Add(ProxyServicesEnum.eSecurity, New SecurityServiceImp(_dbRepository)) 
    _services.Add(ProxyServicesEnum.eStayHistory, New StayHistoryServiceImp(_dbRepository)) 
    _services.Add(ProxyServicesEnum.ePostXml, New PostXmlServiceImp(_dbRepository, ConfigurationServiceSingleton.GetInstance.GetPostXmlConfig)) 
    _services.Add(ProxyServicesEnum.eOxiHttp, New OxiServiceImp(_dbRepository)) 
End Sub 

Public ReadOnly Property Service(ByVal serviceEnum As ProxyServicesEnum) As Object 
    Get 
    If _services.ContainsKey(serviceEnum) Then 
     Return _services.Item(serviceEnum) 
    End If 
    Return Nothing 
    End Get 
End Property 

Public ReadOnly Property GetMeta(ByVal serviceEnum As ProxyServicesEnum) As IDictionary(Of String, MethodIdentityAttribute) 
    Get 
    If _services.ContainsKey(serviceEnum) Then 
     Return _services.Item(serviceEnum).MetaInfo 
    End If 
    Return Nothing 
    End Get 
End Property 

Public Shared Function GetInstance() As ServiceProxySingleton 
    Return NestedPrWireService._instance 
End Function 

Class NestedPrWireService 
    Friend Shared ReadOnly _instance As ServiceProxySingleton = New ServiceProxySingleton() 
    Shared Sub New() 
    End Sub 
End Class 

End Class 

意见和批评，欢迎

很好的方法是使用依赖注入。例如Unity。
