That should work fine unless you have a particular attachment to the List IList property. ---------------------------------------- - Mitch Denny - [EMAIL PROTECTED] - +61 (414) 610-141 - -----Original Message----- From: The DOTNET list will be retired 7/1/02 [mailto:[EMAIL PROTECTED]] On Behalf Of Keith Franklin Sent: Tuesday, 11 June 2002 10:35 To: [EMAIL PROTECTED] Subject: [DOTNET] ISerializable and CollectionBase Hi All, Been exploring a technique that utilizes CollectionBase. Because of a need I need to use manual Serialization and ISerializable rather then simply the Serializable attribute. Now the collection (The internal list) normally serializes no problem with serializable attribute. But with ISerializable I need to use special constructor and the GetObjectData method of ISerializable interface to control the serialization and deserialization process. So I have a constructor like the following one: public AbstractDataBindingCollection(SerializationInfo info, StreamingContext context) { BinaryFormatter listDeSerializer = new BinaryFormatter(); MemoryStream listStream; listStream = (MemoryStream)info.GetValue("list",listStream.GetType()); this.List= (IList)listDeSerializer.Deserialize(listStream); } This does not compile because this.List is not writable it is a read only property. The corresponding GetObjectData compiles: public virtual void GetObjectData(System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context) { BinaryFormatter listSerializer = new BinaryFormatter(); MemoryStream listStream = new MemoryStream(); listSerializer.Serialize(listStream,this.List); info.AddValue("list",listStream); } The alternative that I know of works but I don't like it. The alternative that I have working is to enumerate through the list and add all of the individual items and then in the constructor rebuild the list. Anyone else have a better way of doing this.
