serialization:
1. use attribute
// "[serializable]"
2. formatter
// "binaryformatter binaryformatter = new binaryformatter();"
3.[noserialized]
//example
// if the data can generate based some data, then no need to serialize them.
// overload the onserialization() method to do the caculate work
[serializable]
class products : ideserializationcallback
{
private long statnumber = 1;
private long endnumber;
