How to serialize multiple objects of different types?

Question

I'm trying to serialize an array of objects and a string. This is the serialization code:

FileStream s;
s = new FileStream(savefile.FileName, FileMode.Create, FileAccess.Write);
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(s, ch.chaps);
bf.Serialize(s, txtPassword.Text);
s.Close();

This is the deserialization code:

FileStream s;
s = new FileStream(openfile.FileName, FileMode.Open, FileAccess.Read);
BinaryFormatter bf = new BinaryFormatter();
string password = (string)bf.Deserialize(s);
ch.chaps = (Chapter[])bf.Deserialize(s);
s.Close();
int i;

if (password == txtPassword.Text)
{
    for (i = 0; i <= 1000; i++)
    {
        try
        {
            combChapSelect.Items.Add(ch.chaps[i].chapName);         
        }
        catch
        {
             i = 1000;
        }
    }
}

This is the code and visual studio says there are no errors but the openfiledialog doesn't close when I select a file and nothing happens. Have I done something wrong or is there another way to serialize different object types?

Is Chapter implementing ISerializable? You say you are trying to "serialize" but in your code you call "deserialize". So are you trying to serialize or deserialize? — Fabien Warniez

You're doing this backwards. You have to deserialize in the same order that you serialize.

In your serialization, its chaps-then-password. In your deserialization, its password-then-chaps.

Thank you! That worked. I didn't know that the order mattered.
