向数据库的表中添加数据Ｃ＃

[Wesley]

 private void button_add_Click(object sender, EventArgs e)
        {
            SqlConnection connect = new SqlConnection("server=*****; uid=sa;pwd=******;database=test1");
            connect.Open();

            


            SqlParameter UserName = new SqlParameter("@Name", SqlDbType.Char, 20);
            UserName.Value = this.textBox_name.Text;
            SqlParameter Sex = new SqlParameter("@Sex", SqlDbType.Char, 10);

我怎么样才能把这些数据填到表里呢，不会弄，哪位给点代码
另处，我这个sex是个combobox怎么从里面读出数据并写到数据表里面？
