C # a new class with a single property: get from the database or encapsulate in a new one?

Question

I tried to describe :) This is more a programming style problem than a coding problem itself.

Suppose we have:

AND:

public class MyDict {
     public Dictionary<int,string> dict;
     // do custom-serialization of "dict"
     public void SaveToFile(...);
     // customized deserialization of "dict"
     public void LoadFromFile(...);
} 

AT:

public class MyDict : Dictionary<int,string>
{

}

Which option would be better in terms of programming style? class B: must be / serialized outside.

The main problem is this: is it better to create a new class (which will have only one property - for example, select A :) or create a new derived class, for example opt B :? I do not want any other data processing than adding / removing and de-serializing for a stream.

Thanks in advance!
