<em>asp.net</em>导出数据生成真正的<em>excel</em&

能否把抄问题描述详细点，什么样的html标准文件？
将整个html全部输出execl可以用将页面zhidaoresponse属性更改为application/vnd.ms-excel后直接输出，如果是控件则利用控件的RenderControl方法填充StringWriter 然后输出

我一般都是用gridview导出数据，你看看代码吧 对你有没有帮助， ----------------------按钮事件-------------------protected void Button2_Click(object sender, EventArgs e)
{
Export("application/ms-excel", "sssss.xls");
} private void Export(string FileType, string FileName)
{
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF7;
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);
// turn off paging
GridView1.AllowPaging = false;
this.GridView1.DataBind(); GridView1.RenderControl(hw);
Response.Write(tw.ToString());
Response.End(); // turn the paging on again
GridView1.AllowPaging = true;
this.GridView1.DataBind(); } 下面这句636f70797a64334不加的话回出错误 public override void VerifyRenderingInServerForm(Control control)
{ }页面：EnableEventValidation = "false"
绑定数据后

System.Web.HttpContext.Current.Response.Clear();
System.Web.HttpContext.Current.Response.Charset = "GB2312";
// System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
// 添加头信息，为"文件下载/另存为e79fa5e98193e4b893e5b19e339"对话框指定默认文件名
System.Web.HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=myU.xls");
// 添加头信息，指定文件大小，让浏览器能够显示下载进度
// System.Web.HttpContext.Current.Response.AddHeader("Content-Length",sb.ToString());

// 指定返回的是一个不能被客户端读取的流，必须被下载
System.Web.HttpContext.Current.Response.ContentType = "application/ms-excel";

// 把文件流发送到客户端
System.Web.HttpContext.Current.Response.Write(sb.ToString());
// 停止页面的执行

System.Web.HttpContext.Current.Response.End();

StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
HtmlTextWriter htw = new HtmlTextWriter(sw);
Page page = new Page();
HtmlForm form = new HtmlForm();
GridView1.EnableViewState = false;
page.EnableEventValidation = false;
page.DesignerInitialize();
page.Controls.Add(form);
form.Controls.Add(GridView1);
page.RenderControl(htw);
Response.Clear();
Response.Buffer = true;
Response.ContentType = "application nd.ms-excel";
string name = "Keyword_Report-" + System.DateTime.Now.ToShortDateString();
Response.AddHeader("Content-Disposition", "attachment;filename=" + name + ".xls");
Response.Charset = "gb2312";
Response.ContentEncoding = Encoding.UTF8;
Response.Write(sb.ToString());
Response.End();
