Excel导入数据到sqlserver

1、读取excel数据到dataset

public static System.Data.DataSet ExcelSqlConnection(string filepath, string tableName)    {        string strCon = "PRovider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filepath + ";Extended Properties='Excel 8.0;HDR=YES;IMEX=1'";        OleDbConnection ExcelConn = new OleDbConnection(strCon);        try        {            string strCom = string.Format("SELECT * FROM [Sheet1$]");            ExcelConn.Open();            OleDbDataAdapter myCommand = new OleDbDataAdapter(strCom, ExcelConn);            DataSet ds = new DataSet();            myCommand.Fill(ds, "[" + tableName + "$]");            ExcelConn.Close();            return ds;        }        catch        {            ExcelConn.Close();            return null;        }    }

2、将数据写入到数据库

 protected void Button2_Click(object sender, EventArgs e)    {        string filename = FileUpload1.FileName;        string savePath = Server.MapPath(("~/fujian/") + filename);        FileUpload1.SaveAs(savePath);        DataSet ds = ExcelSqlConnection(savePath, filename);        //GridView1.DataSource = ds;        //GridView1.DataBind();        DataRow[] dr = ds.Tables[0].Select();        for (int i = 0; i < dr.Length; i++)        {            SqlConnection myconn = myconnect();            myconn.Open();                        string title = dr[i]["名称"].ToString();            string huanxianweizhi = dr[i]["环线位置"].ToString();            string quyu = dr[i]["区域"].ToString();            string sqlstr1 = "select * from dbo.test where name='" + quyu + "'";    //区域中间表转换            SqlCommand myCmd1 = new SqlCommand(sqlstr1, myconn);            SqlDataAdapter mydata = new SqlDataAdapter(myCmd1);            DataSet my = new DataSet();            mydata.Fill(my);            GridView1.DataSource = my;            GridView1.DataBind();            string quyu1 = my.Tables[0].Rows[0][0].ToString(); ;            //SqlDataAdapter adapt = new SqlDataAdapter(sqlstr1, myconn);            DataSet ds1 = new DataSet();            string zuoluo = dr[i]["座落"].ToString();            string yongtu = dr[i]["用途"].ToString();            string chengjiaotaoshu = dr[i]["成交套数"].ToString();            string jianzhumianji = dr[i]["建筑面积"].ToString();            string chengjiaozongjia = dr[i]["成交总价"].ToString();            string dangrijunjia = dr[i]["当日均价"].ToString();            string chengjiaoriqi = dr[i]["成交日期"].ToString();            string qitashuoming = dr[i]["其他说明"].ToString();            string bankuai = dr[i]["板块"].ToString();            //SqlConnection myconn = myconnect();            //myconn.Open();            string sqlstr = "insert into dbo.youweishuju(名称,环线位置,区域,座落,用途,成交套数,建筑面积,成交总价,当日均价,成交日期,其他说明,板块)values('" + title + "','" + huanxianweizhi + "','" + quyu1 + "','" + zuoluo + "','" + yongtu + "','" + chengjiaotaoshu + "','"+ jianzhumianji +"','"+ chengjiaozongjia +"','"+ dangrijunjia +"','"+ chengjiaoriqi +"','"+ qitashuoming +"','"+ bankuai +"')";            //string sqlstr = "insert into dbo.youweishuju(名称)values('" + title + "')";            SqlCommand myCmd = new SqlCommand(sqlstr, myconn);            myCmd.ExecuteNonQuery();            myconn.Close();        }    }
