excel导入数据到sqlserver

一，ADO.net的方式

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();}}

　　二，linq的方式

1、读取excel数据并且验证

 protected void UpLoad(){this.GvReport.DataSource = null;this.GvReport.DataBind();var fileName = string.Empty;try{if (this.FileUpload1.PostedFile != null && !string.IsNullOrEmpty(this.FileUpload1.PostedFile.FileName)){if

= Path.GetTempFileName();this.FileUpload1.PostedFile.SaveAs(fileName);connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;" + "Data Source=" + fileName + ";" + "Extended properties='Excel 12.0;HDR=yes;IMEX=1'";var sql = "Select * from [Sheet1$]";var dataAdapter = new OleDbDataAdapter(sql, connectionString);var ds = new DataSet();dataAdapter.Fill(ds, "ExcelInfo");var dataTable =
