基於Asp.net下Excel批量導入SQLserver數據庫

關鍵代碼

protected void Button1_Click(object sender, EventArgs e)

下載Excel樣例

//c#標准下載文件代碼
protected void LinkButton1_Click(object sender, EventArgs e)
    {
        string _filepath = "~/upfiles/樣本.xls";
        string _filename = "樣本.xls";
        if (System.IO.File.Exists(MapPath(_filepath)))
        {
            Response.Clear();
            Response.Buffer = true;

            Response.AddHeader("Content-Disposition", "attachment;filename=" + _filename);
            Response.ContentType = "application/unknow";
            Response.TransmitFile(_filepath);
            Response.End();

        }
    }
