nothing in your class that requires custom serialization. All you have
to
do is add the Serializable attribute, and your serialization should work
fine. ISerializable only needs to be implemented when there are other
things (besides the fields in your class) that you want to serialize, or
they require certain logic to be executed.
Hope this helps.

While executing BinaryFormatter.Deserialize() I get:
System.InvalidCastException: Specified cast is not valid.
I implemented ISerializable interface. What may be a problem?
Could you post a short but complete program which demonstrates the
problem?
See
http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.
