Newbie Q: Serialization and MeI'm just beginning to learn VB.Net so if this seems dumb, please forgive me. I have 2 objects and I want to make a deep copy of one into the other. I effectively want to clone an object into Me. (I'm also looking to learn about serialisation). Public Class MyClass Public Function Clone(AnObject as MyClass) as Integer 'ideally!!! make deep copy of all members of AnObject into Me If CopyObject(AnObject, Me) = Success then ''' endif end Class .... somewhere else Public Shared Function CopyObject(of T)(Byval Source as T, Byref Target as T) as Integer 'use serialization to make a deep copy but Target is 'Me' End Function I've found several examples of deep copying objects such as Public Function Clone() As MyClass Dim ms As Stream = New MemoryStream() Dim bf As BinaryFormatter = New BinaryFormatter() bf.Serialize(ms, Me) ms.Position = 0 Return CType(bf.Deserialize(ms), MyClass) End Function... but this serializes Me so Me is the Source, but really I want to serialise the Object passed into Me and set all the members of Me through serialization so Me is effectively the Target. Is there a way of doing this generically or is the only way to clone an object into Me on a member-by-member basis. Thanks Simon This is generally accomplished with a "copy constructor" as opposed to
cloning. At the very least, I'd rename the method you are trying to create to "Copy" or "CopyFrom". Why don't you just do a member-by-member assignment in the method (either the copy constructor or the Copy methods), cloning or otherwise manually creating and populating sub objects (since you said you wanted a deep copy)?

lose a bit of control over the process if you want it completely automatic. Probably no big deal though, I guess. Another approach you could try is to place all of you data in a private / inner class and then use your serialization trick on *that* class, an instance of which be obtained via friend / private / or superclass methods. Once you have the clone of the data, just assign it to your own data variable. Note in this sample that the CloneData method is PRIVATE: Public Class MyExampleClass Private m_Data As New MyExampleClassData Public Property Name() As String Get Return m_Data.Name End Get Set(ByVal Value As String) m_Data.Name = Value End Set End Property Public Sub CopyFrom(ByVal mec As MyExampleClass) m_Data = mec.CloneData() End Sub Private Function CloneData() As MyExampleClassData Dim ms As Stream = New MemoryStream Dim bf As BinaryFormatter = New BinaryFormatter bf.Serialize(ms, m_Data) ms.Position = 0 Return CType(bf.Deserialize(ms), MyExampleClassData) End Function <Serializable()> _ Private Class MyExampleClassData Public Name As String End Class End Class Simon Woods wrote: Show quoteHide quote > TDC wrote: > > This is generally accomplished with a "copy constructor" as opposed to > > cloning.
