Asp.net中如何导出Excel文档（Gridview）

Asp.net中如何导出Excel文档（Gridview）2015-04-27主要思路，通过GridView来导出文档。新建一个Aspx页面，页面创建GridView控件，后台绑定好数据源。
然后load中直接打印即可导出

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="性别" /><asp:BoundField DataField="BirthDay" HeaderText="出生日期" /><asp:BoundField DataField="StudentId" HeaderText="身份证号" /><asp:BoundField DataField="JieduId" HeaderText="借读证号" /><asp:BoundField DataField="Familymemberinfo_Name1" HeaderText="第一监护人姓名" /></Columns><HeaderStyle BackColor="Azure" Font-Size="12px" HorizontalAlign="Center" /><RowStyle HorizontalAlign="Center" /><PagerStyle HorizontalAlign="Center" /></asp:GridView>

后台：

/// <summary>/// 定义导出Excel的函数/// </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++）{//这里给指定的列编辑格式，将数字输出为文本，防止数字溢出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>/// 此方法必重写，否则会出错/// </summary>/// <param name="control"></param>public override void VerifyRenderingInServerForm（Control control）{}
