WCF - 我可以使用现有类型通过我的 WCF 服务传递吗

Question

我有一个服务。我有一个现有的业务对象类。我想知道的是如何从业务对象程序集中通过 WCF 传递类，而无需在附加或标记时在 WCF 站点中创建新类？

这是一个现有的 UDT： 命名空间示例： Application.BusinessObjects.Appointments

Public Structure AppointmentResource
    Private _id As String
    Private _type As ResourceTypeOption
    Private _name As String

    Property id() As String
        Get
            Return _id
        End Get
        Set(ByVal value As String)
            _id = value
        End Set
    End Property

    Property type() As ResourceTypeOption
        Get
            Return CType(_type, Int32)
        End Get
        Set(ByVal value As ResourceTypeOption)
            _type = value
        End Set
    End Property

    Property Name() As String
        Get
            Return _name
        End Get
        Set(ByVal value As String)
            _name = value
        End Set
    End Property

    Public Sub New(ByVal id As String, ByVal type As ResourceTypeOption, ByVal name As String)
        _id = id
        _type = type
        _name = name
    End Sub
End Structure

这是我使用数据协定属性创建的同一命名空间： 命名空间示例： Application.Service.Appointments

<DataContract()> _
    Public Structure AppointmentResource
        Private _id As String
        Private _type As ResourceTypeOption
        Private _name As String

        <DataMember()> _
        Property id() As String
            Get
                Return _id
            End Get
            Set(ByVal value As String)
                _id = value
            End Set
        End Property

        <DataMember()> _
        Property type() As ResourceTypeOption
            Get
                Return CType(_type, Int32)
            End Get
            Set(ByVal value As ResourceTypeOption)
                _type = value
            End Set
        End Property

        <DataMember()> _
        Property Name() As String
            Get
                Return _name
            End Get
            Set(ByVal value As String)
                _name = value
            End Set
        End Property

        Public Sub New(ByVal id As String, ByVal type As ResourceTypeOption, ByVal name As String)
            _id = id
            _type = type
            _name = name
        End Sub
    End Structure

有一种简单的方法可以在客户端和服务之间共享类型，只需在添加服务引用之前向客户端添加对共享类型程序集的引用即可。

您可以在那里找到详细的场景和示例项目：

ResourceTypeOption 似乎也是一个自定义类，因此您可以将其定义为其自己的类中的协定的一部分。客户必须了解这一点，因此需要自己的合同。客户端已经知道如何处理字符串等 CLR 类型。任何其他自定义类型也必须在合同中定义。
