ASP.net中导出Excel的简单方法

      下面介绍一种ASP.net中导出Excel的简单方法

      先上代码:前台代码如下(这是自己项目里面写的一点代码先贴出来吧)

     <div id="export" runat="server" style="width: 700px; margin-left: auto; margin-right: auto;">
        <!--startprint-->
        <table width="100%" border="0" align="center" cellpadding="0" cellspacing="0" style="word-break: break-all;">
            <tr>
                <td align="center" colspan="7" valign="middle" style="font-size: 14px; font-family: 宋体; font-weight: bold;
                    height: 30px">
                    <span id="spanYEAR" runat="server"></span>年<span id="spanMONTH" runat="server"></span>月分公司月度需求生产任务汇总
                </td>
            </tr>   
            <tr>
                <td align="right" valign="middle" colspan="7">
                    <table width="100%">
                        <tr>
                            <td colspan="2" align="left">
                                &nbsp;数量单位:支
                            </td>
                            <%--   <td width="10%" align="center" style="font-weight: bold;">
                                &nbsp;
                            </td>--%>
                            <td width="20%" align="center" style="font-weight: bold;">
                             
                            </td>
                            <td width="25%" colspan="2" align="center">
                             
                            </td>
                            <td width="40%" colspan="2" align="center">
                            
                            </td>
                        </tr>
                    </table>
                </td>
            </tr>      
        </table>
        <table width="100%" border="0" align="center" cellpadding="0" cellspacing="0" style="font-size: 12px;
            font-family: 宋体; word-break: break-all;">
            <tr>
                <td colspan="4" align="left" valign="top">
                    <div id="div" runat="server">
                        <table width="100%" border="1" align="center" cellpadding="0" cellspacing="0" style="font-family: 宋体;
                            word-break: break-all;">
                            <tr>
                                <td width="8%" align="center" style="font-weight: bold; height: 25px">
                                    序号
                                </td>
                                <td width="20%" align="center" style="font-weight: bold;">
                                    硒鼓型号
                                </td>
                                <td width="12%" align="center" style="font-weight: bold;">
                                    硒鼓类别
                                </td>
                                <td width="15%" align="center" style="font-weight: bold;">
                                    第一批次
                                </td>
                                <td width="15%" align="center" style="font-weight: bold;">
                                    第二批次

                                    第四批次
                                </td>
                            </tr>
                            <asp:Repeater ID="rptXQPC" runat="server">
                                <ItemTemplate>
                                    <tr>
                                        <td width="8%" align="center" height="25px">
                                            <%#Eval("ROWID")%>
                                        </td>
                                        <td width="20%" align="center">

                                        </td>
                                    </tr>
                                </ItemTemplate>
                            </asp:Repeater>
                            <tr>
                                <td colspan="3" width="40%" align="right" style="font-weight: bold; height: 25px">
                                    批次合计:
                                </td>
                                <td width="15%" align="center" style="font-weight: bold;">
                                   <div id="divFirst" runat="server"></div>
                                </td>
                                <td width="15%" align="center" style="font-weight: bold;">
                                    <div id="divSecond" runat="server"></div>
                                </td>
                                <td width="15%" align="center" style="font-weight: bold;">
                                    <div id="divThird" runat="server"></div>
                                </td>
                                <td width="15%" align="center" style="font-weight: bold;">
                                    <div id="divFourth" runat="server"></div>
                                </td>
                            </tr>
                        </table>
                    </div>
                </td>
            </tr>
        </table>
        <!--endprint-->
    </div>

后台代码如下 :

    绑定Repeater数据这里接就不多做介绍了(用的Repeater嵌套)

    下面贴出后台导出Excel的方法:

   

 /// <summary>
    /// 将数据导出到excel,与下面的函数同时使用才能正常工作
    /// </summary>
    /// <param name="ctl"></param>
    public void ToExcel(System.Web.UI.Control ctl)
    {
        HttpContext.Current.Response.Clear();

 

        HttpContext.Current.Response.Charset = "";
        string filename = "Report" + System.DateTime.Now.ToString("_yyyyMMddHHmm");
        HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" +

 

        System.Web.HttpUtility.UrlEncode(filename, System.Text.Encoding.UTF8) + ".xls");

 

        HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
        HttpContext.Current.Response.ContentType = "application/ms-excel";//image/JPEG;text/HTML;image/GIF;vnd.ms-excel/msword  
        ctl.Page.EnableViewState = false;
        System.IO.StringWriter tw = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
        ctl.RenderControl(hw);
        HttpContext.Current.Response.Write(tw.ToString());
        HttpContext.Current.Response.End();
    }

 

   后台导出Excel时直接调用为  ToExcel(this.export);  这里的export是加了runat="server"的div名称,

   这句代码的意思是调用ToExcel的方法导出export里面的页面数据(页面上的数据是怎么展示的,导出来以后的Excel数据会以同样的方式展示)

   可以使用这个解决导出乱码问题:HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default//获取当前页面的编码
