Is a binary-serialized DataSet versioning tolerant?

1st I serialize a DataSet (contains 14 DataTables) into file, with
BinaryFormatter.
2nd I change some columns in a DataTable.
3rd When I now Deserialize the DataSet from bin file got I problems ??

Thanks in advance

Yu will get the same dataset that when you serialized it the first
time.

Just to add, you will get the same result using any other
serialization method.

Remember, you will get a NEW instance of a Dataset (which contains all
the dattables) . It has no knowledge that the "original" instance
changed.

Thanks for the answer!

I have done the following:
....
BinaryFormatter f = new BinaryFormatter();

using ( FileStream fs = new FileStream( @"MyFile.bin", FileMode.Open ) )
{
dsDes = (DataSet1)f.Deserialize( fs );
}

The cast (DataSet1) works although I have deleted a column in a DataTable
in the DataSet1 before I called the Deserialize() function.
