Asp.net中匯出Excel文檔（Gridview）

主要思路，通過GridView來匯出文檔。 建立一個Aspx頁面，頁面建立GridView控制項，後台綁定好資料來源。
然後load中直接列印即可匯出前台的GridView

<asp:GridView ID="GridView1" BorderColor="Black" runat="server" AutoGenerateColumns="False"            Font-Size="12px" Width="656px" AllowSorting="True" Height="172px">            <Columns>                <asp:BoundField DataField="Name" HeaderText="姓名" />                <asp:BoundField DataField="Sex" HeaderText="性別" />                <asp:BoundField DataField="BirthDay" HeaderText="出生日期" />                <asp:BoundField DataField="StudentId" HeaderText="社會安全號碼" />                <asp:BoundField DataField="JieduId" HeaderText="借讀證號" />                <asp:BoundField DataField="Familymemberinfo_Name1" HeaderText="第一監護人姓名" />            </Columns>            <HeaderStyle BackColor="Azure" Font-Size="12px" HorizontalAlign="Center" />            <RowStyle HorizontalAlign="Center" />            <PagerStyle HorizontalAlign="Center" />        </asp:GridView>

後台：

        /// <summary>        /// 定義匯出Excel的函數        /// </summary>        /// <param name="FileType"></param>        /// <param name="FileName"></param>        private void Export(string FileType, string FileName)        {            for (int i = 0; i < GridView1.Rows.Count; i++)            {                //這裡給指定的列編輯格式，將數字輸出為文本，防止數字溢出                GridView1.Rows[i].Cells[3].Attributes.Add("style", "vnd.ms-excel.numberformat:@");            }            Response.Charset = "GB2312";            //Response.ContentEncoding = System.Text.Encoding.UTF8;            Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");            Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());            Response.ContentType = FileType;            this.EnableViewState = false;            StringWriter tw = new StringWriter();            HtmlTextWriter hw = new HtmlTextWriter(tw);            GridView1.RenderControl(hw);            Response.Write(tw.ToString());            Response.End();        }        /// <summary>        /// 此方法必重寫，否則會出錯        /// </summary>        /// <param name="control"></param>        public override void VerifyRenderingInServerForm(Control control)        {        }
