Question

this can probably be done with a foreach loop. However.. while / for should also work. If I have a class MyClass, and writes 100 objects of MyClass. How can I stop at end of file when i Deserialize? Thanks in Advance

FileStream inStr = new FileStream(@"file.dat", FileMode.Open);
BinaryFormatter bf = new BinaryFormatter();

MyClass myclass = new MyClass();

while (???) // What to put here? EOF / End of stream check
{
myclass = (MyClass)bf.Deserialize(inStr);
//...
}

If you want to save and load a list of your MyClass why not save a List object.

Save

List<MyClass> list = new List<MyClass>();
// add to your list
FileStream stream = new FileStream(@"file.dat", FileMode.Create);
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, list);
stream.Close();

Load

FileStream inStr = new FileStream(@"file.dat", FileMode.Open);
BinaryFormatter bf = new BinaryFormatter();
List<MyClass> list = bf.Deserialize(inStr) as List<MyClass>;
