XML serialize multiple classes

Question

So I've got a bit of a problem I'm made a class that i have to use 7 times (one for each day of the week) I have the serialize set this way

 FileStream stream = new FileStream("C:\\employee.xml", FileMode.OpenOrCreate);
            XmlSerializer serializer = new XmlSerializer(typeof(Day));
            serializer.Serialize(stream, monday);
            serializer.Serialize(stream, tuesday);
            serializer.Serialize(stream, wednesday);
            serializer.Serialize(stream, thursday);
            serializer.Serialize(stream, friday);
            serializer.Serialize(stream, saturday);
            serializer.Serialize(stream, sunday);

problem is when I unserialize it only works if i only save the class once, is there anything that has to be done differently for more then 1 instance of the same class?

 FileStream stream = new FileStream("C:\\employee.xml", FileMode.Open);
            XmlSerializer serializer = new XmlSerializer(typeof(Day));
            monday = (Day)serializer.Deserialize(stream);

Thanks :)

Just as Adam proposed why don't you create a serializable class called WeekInfo or DaysofWeek where you have 7 class variables that store Day information. Then serialize/unserialize the WeekInfo or DaysofWeek class instead of your Day class.

Adam · Answer

Ok then create a class called something like DaysOfWeek and implement 7 public properties of type 'Day' and do your seriaization on the DaysOfWeek instance.

It's not overwriting but it's putting the same class over and over on the file with different values so the deserializer can only read the first one but even at that it gives an error because it finds more then one.

Marco Off the top of my head I would say that you are overwriting the data in your stream each time you call Serialize() in your code sample. Based on your code you will end up with sunday only serialized and written to the file. Adam
