DeSerialization doesn’t work though i Implement GetObjectData method and Constructor

[punitsinghi]

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 
    {
        static Dictionary<int, string> dict = new Dictionary<int,string>();
        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);
}
}

Try adding an Application.DoEvents() and maybe a Thread.Sleep() after you call the bf.Serialize() call. Or, if it supposts it, a Flush() call.
It is sometimes the case with IO calls and streams, that the function returns before it is actually "done" and you then you immediatly dispose and close of the object, meaning it never gets to finish.

             fileStream = new FileStream("test.binary", FileMode.Open);
        bf = new BinaryFormatter();
            myClass = (MyClass1)bf.Deserialize(fileStream);
 

I realize this is just to test whether or not the save worked but take it out of the save routine. It doesn't really belong there.

If you want to test the saving then call the save routine... let it complete and exit... then call the load routine to check it.
