Question

我正在尝试将DTO对象映射到CSLA.NET（请参阅：http://www.lhotka.net/cslanet/）对象。为了这个问题，我使用了Lhotka为他的框架提供的示例应用程序。下面是我正在使用的类的示例（为了清楚起见，我删除了大多数属性和方法）：

 <Serializable()> _
    Public Class Project
        Inherits BusinessBase(Of Project)


        Private mId As Guid = Guid.NewGuid
        Private mName As String = ""

        Private mResources As ProjectResources = _
          ProjectResources.NewProjectResources()

        <System.ComponentModel.DataObjectField(True, True)> _
        Public ReadOnly Property Id() As Guid
            <System.Runtime.CompilerServices.MethodImpl(Runtime.CompilerServices.MethodImplOptions.NoInlining)> _
            Get
                'CanReadProperty(True)
                Return mId
            End Get
        End Property


        Public Property Name() As String
            <System.Runtime.CompilerServices.MethodImpl(Runtime.CompilerServices.MethodImplOptions.NoInlining)> _
            Get
                'CanReadProperty(True)
                Return mName
            End Get
            <System.Runtime.CompilerServices.MethodImpl(Runtime.CompilerServices.MethodImplOptions.NoInlining)> _
            Set(ByVal Value As String)
                'CanWriteProperty(True)
                If Value Is Nothing Then Value = ""
                If mName <> Value Then
                    mName = Value
                    PropertyHasChanged()
                End If
            End Set
        End Property



        Public ReadOnly Property Resources() As ProjectResources
            Get
                Return mResources
            End Get
        End Property


    End Class




    Public Class ProjectDTO


        Private _id As Guid
        Public Property Id() As Guid
            Get
                Return _id
            End Get
            Set(ByVal value As Guid)
                _id = value
            End Set
        End Property



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


        Private _resources As New List(Of ProjectResourceDTO)()
        Public Property MyResources() As List(Of ProjectResourceDTO)
            Get
                Return _resources
            End Get
            Set(ByVal value As List(Of ProjectResourceDTO))
                _resources = value
            End Set
        End Property

    End Class


Mapper.CreateMap(Of ProjectDTO, Project)().ConstructUsing(Function(src As ProjectDTO) Project.NewProject())
Mapper.CreateMap(Of ProjectResourceDTO, ProjectResource)()
Mapper.CreateMap(Of ResourceDTO, Resource)()

我遇到的问题与Resources readonly属性的映射有关，该属性是继承自BusinessListBase的集合。向此集合添加项目的唯一方法是执行方法Assign（resourceId）。

是否有人知道如何将DTO对象映射回CSLA对象。即我该如何配置映射器？请注意，在这种特殊情况下，使用资源成员的解析器没有帮助。

谢谢！

Answer 1

Automapper不会在这里帮助你，因为它只能调用公共API。

使用常规CSLA.NET编码从DTO构建您的ProjectResources列表。根据CSLA惯例，在加载每个ProjectResource时，您应该调用LoadProperty<T>(IPropertyInfo pi, T value)来填充每个属性。

使用Automapper映射到CSLA对象
