You can use ExecuteNonQuery like cmd.ExecuteNonQuery(); It returns int value. Use it like this;

int i = cmd.ExecuteNonQuery();

And also ExecuteReader() works like this;

SqlDataReader reader = command.ExecuteReader();
        while (reader.Read())
        {
            Console.WriteLine(String.Format("{0}", reader[0]));
        }

You can read returning data's column. Like first column reader[0], second column reader[1] etc.

But before all this information, if you are new to programming, you can find a lot of book proposal and useful informations on Stackoverflow. Check these articles;
