What is the best way to create a clone of a DTO? There is not an ICloneable interface or a BinaryFormatter class in Silverlight. Is reflection the only way?
答
这是我们提供的用于克隆的代码.这适用于Silverlight 2& 3.
Here is the code we came up with for cloning. This works in Silverlight 2 & 3.
Public Shared Function Clone(Of T)(ByVal source As T) As T
Dim serializer As New DataContractSerializer(GetType(T))
Using ms As New MemoryStream
serializer.WriteObject(ms, source)
ms.Seek(0, SeekOrigin.Begin)
Return DirectCast(serializer.ReadObject(ms), T)
End Using
End Function
