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.
