Question

I am using serialization to write with Append some contacts with their name and phone to a file, I am writing each contact alone by append it to the file.

I want to read these contacts from the file and put them in a ListView.

Stream stream = File.Open("Contacts.dat", FileMode.Open);
BinaryFormatter BFormatter = new BinaryFormatter();
Contacts contact = (Contacts)BFormatter.Deserialize(stream);
listView1.Items.Add(new ListViewItem(new string[] { "", contact.name, contact.phone }));

After I am doing the above code I get only one contact and if I deserialize the stream again i get the next contact

Contacts contact2 = (Contacts)BFormatter.Deserialize(stream);
listView1.Items.Add(new ListViewItem(new string[] { "", contact2.name, contact2.phone}));

How can I read all the contacts?
or how can I know that the stream is end?

You can check the stream Position property against stream Length property, assuming your are refering to file stream
