Hi,

I have a static generic dictionary in a class. As static memeber cannot serialized so i have implented ISerializable interface and method GetObjectData to serialize. I have a constructor which will also accept SerializationInfo and StreamingContext to deserliaze the dictionay. Now when i try to serialize and deserialize , it always return 1(thoug i added 2 entries). please find the pseduo code-

[Serializable]
public class MyClass : ISerializable
{
  internal  static Dictionary<long, string> dict = new Dictionary<long,string>();

  public void GetObjectData(SerializationInfo info, StreamingContext context)
  {
   info.AddValue("static.dic", MyClass1.dict, typeof(Dictionary<long, string>));
  }

  public MyClass(SerializationInfo info, StreamingContext context)
  {
    MyClass.dict= (Dictionary<long, string>)info.GetValue("static.dic", 
       typeof(Dictionary<long, string>));

  }
  public void Add()
  {
    dict.Add(21, "11");
  }

  public MyClass()
  {
    dict.Add(21, "11");
  }
}


  public class MyClass 
  {       
        MyClass myClass = new MyClass();

        public static void Main()
        {
           myClass.Add();

           FileStream fileStream = new FileStream("test.binary", FileMode.Create);

           IFormatter  bf = new BinaryFormatter();

           bf.Serialize(fileStream, myClass);

            fileStream.Dispose();

            fileStream.Close();

            fileStream = new FileStream("test.binary", FileMode.Open);

            bf = new BinaryFormatter();

            myClass = (MyClass1)bf.Deserialize(fileStream);
     }
}
