Hi i am serializing a 'ref struct' object as follows :

private: void Seri( String ^path, Object^ obj )
    {
        FileStream^ fileStrm ;
        try
        {
        //Serialize entire object into Binary stream
            fileStrm = File::Open( path , FileMode::Create );
            BinaryFormatter^ binFormatter = gcnew BinaryFormatter();
            binFormatter->Serialize(fileStrm, obj );
        }
        finally
        {
            if (fileStrm != nullptr )
            {
                fileStrm->Flush();
                fileStrm->Close();
            }
        }
    }

private: Object ^ Desi(String ^path)
    {
        FileStream ^fileStream ;
        Object ^obj ;
        try
        {
            fileStream = File::Open(path ,FileMode::Open );
            BinaryFormatter^ binFormatter = gcnew BinaryFormatter();
            obj = binFormatter->Deserialize(fileStream);
        }
        finally
        {
            if (fileStream != nullptr )
            {
                fileStream->Close();
            }
        }
        return obj;

    }

// now i am serializing it in follwing way...

WayPoint2 ^waypoint1 =  gcnew WayPoint2( gcnew LatLog(41.0,-75.0),
"First","Description", DateTime::Now.AddHours( -10) ,
DateTime::Now.AddHours( -8) ) ;

Seri( "a.waypoint", waypoint1 );

//Serialization works fine.... but following deserialization throws me
exception...

WayPoint2 ^waypoint = ( WayPoint2 ^) this->Desi("a.waypoint") ;

// Exception :
'System.Runtime.Serialization.SerializationException' occurred in
mscorlib.dll
Additional information: Binary stream '169' does not contain a valid
BinaryHeader. Possible causes are invalid stream or object version
change between serialization and deserialization.

// The definition of struct WayPoint2 is as follows
[Serializable]
public ref struct WayPoint2
   {
    public :
        LatLog ^LatLong;
        String ^Name;
        String ^Description;
        DateTime ^Arrival;
        DateTime ^Departure;
        WayPoint2()
        {
            this->LatLong = gcnew LatLog();
            this->Name = String::Empty ;
            this->Description = String::Empty ;
            this->Arrival = DateTime::Now ;
            this->Departure = DateTime::Now ;
        }

        WayPoint2 ( LatLog ^latlog, String ^name, String ^description,
DateTime ^arrival, DateTime ^departure)
        {
            this->LatLong = latlog;
            this->Name = name ;
            this->Description = description ;
            this->Arrival = arrival ;
            this->Departure = departure ;
        }
}

Can any one help me to sesolve this problem? i have taken care of
Flushing, null references; still its not working.
