excel導入、導出數據

編輯:.NET實例教程

一、數據導出到Excel



 public static void ResponseExcel(Control ControlId, HttpResponse Response, string FileName)
    ...{
        Response.Clear();
        Response.ContentType = "application/vnd.ms-Excel";
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
        Response.AddHeader("Content-Disposition", "inline;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8) + ".xls");
        System.Text.StringBuilder sb = new System.Text.StringBuilder();
        System.IO.StringWriter sw = new System.IO.StringWriter(sb);
        System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(sw);
        sb.Append("<Html><head>");
        sb.Append("<meta http-equiv=Content-Type content=text/Html;charset=UTF-8>");
        sb.Append("</head><body>");
        ControlId.RenderControl(hw);
        sb.Append("</body></Html>");
        Response.Write(sb.ToString());
        Response.End();
    }

數據導入數據庫

 



  public static DataSet ExcelToDataSet(string opnFileName)
        ...{
            string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + opnFileName + ";Extended PropertIEs="Excel 8.0;HDR=YES;IMEX=1"";

            OleDbConnection conn =&nbsp;new OleDbConnection(strConn);
            string strExcel = "";
            OleDbDataAdapter myCommand = null;
            DataSet ds = new DataSet();
            strExcel = "select * from [sheet1$]";
            try
            ...{
                conn.Open();
                myCommand = new OleDbDataAdapter(strExcel, strConn);
                myCommand.Fill(ds, "dtSource");
                return ds;
            }
            catch (Exception ex)
            ...{

                return ds;
            }
            finally
            ...{
                conn.Close();
      conn.Dispose();
            }
        }
