More about this : Getting the identity of the most recently added record

The Jet 4.0 provider supports @@Identity

string query = "Insert Into Categories (CategoryName) Values (?)";
string query2 = "Select @@Identity";
int ID;
string connect = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|Northwind.mdb";
using (OleDbConnection conn = new OleDbConnection(connect))
{
  using (OleDbCommand cmd = new OleDbCommand(query, conn))

  {
    cmd.Parameters.AddWithValue("", Category.Text);
    conn.Open();
    cmd.ExecuteNonQuery();
    cmd.CommandText = query2;
    ID = (int)cmd.ExecuteScalar();
  }
}
