那位大神可以帮忙啊？很急的。我想把作家那张表里的作家姓名添加到combobox中，调试的时候我把combobox控件点开里面是空的，我应该怎么写代码？越详细越好。 谢谢！

           

谢谢！还有一个问题。怎么能将数据库里的数据在gridview中显示，我们调试的时候没有错，可是显示不出结果，gridview里是空的，连表格都不出，下面是我们的代码。
using System;
using System.Collections.Generic;
using
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;

namespace all
{
    public partial class shop : Form
    {
        public shop()
        {
            InitializeComponent();
            this.IsMdiContainer = true;
        }
        SqlDataAdapter sqlDataAdapter;
        DataSet abc;

        private void shop_Load(object sender, EventArgs e)
        {
            SqlConnection myConnection = new SqlConnection();
            myConnection.ConnectionString = "server=PC-20111126CNWU;uid=sa;pwd=123;database=store";
            SqlCommand sqlCommand = new SqlCommand();
            sqlCommand.Connection = myConnection;
             = CommandType.Text;
             = "SELECT sno as 编号,name as 店名,time as 经营时间,star as 星级指数 from shop1";
            

            sqlDataAdapter = new SqlDataAdapter();
            sqlDataAdapter.SelectCommand = sqlCommand;
            SqlCommandBuilder builder = new SqlCommandBuilder(sqlDataAdapter);

            abc = new DataSet();
            sqlDataAdapter.Fill(abc, "shop1");



            dataGridView1.DataSource = abc;
            dataGridView1.DataMember = "shop1";
            
        }

            }
}

能不能帮我看一下下面的代码什么意思？我看不懂
DataRow myDR = abc.Tables["writer"].NewRow();
   if (dataGridView1.RowCount > 1)
       myDR[0] = int.Parse(abc.Tables["writer"].Rows[(dataGridView1.RowCount - 2)][0].ToString()) + 1;
    else
        myDR[0] = 1;
        myDR[1] = textBox1.Text.Trim();
