HTML页面的导出，包括Excel和Word导出

//导出到Excel --- 全部导出，可以设置一些隐藏进行导出
protected void btnExport_Click(object sender, EventArgs e)
{
div_table.InnerHtml = hfdHtml.Value;//将页面内容重新放回去，因为后台按钮会冲掉已经生成的页面
btnExport.Visible = false;//导出按钮设置为不可见
string strFileName = DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls";
System.Web.HttpContext.Current.Response.Clear();
System.Web.HttpContext.Current.Response.ClearHeaders();
System.Web.HttpContext.Current.Response.Buffer = false;
System.Web.HttpContext.Current.Response.ContentType = "application/octet-stream";
System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + strFileName);
}
//导出word操作，本实例可以导出html样式

protected void btnExport_Click(object sender, EventArgs e)
{
divAdd.Visible = false;//需要隐藏的div
string strFileName = DateTime.Now.ToString("yyyyMMddHHmmss") + ".doc";
Response.Buffer = true;
System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + strFileName);
Response.ContentType = "application/ms-word";
HttpContext.Current.Response.Charset = "UTF-8";
this.EnableViewState = false;//初始化HtmlWriter
System.IO.StringWriter writer = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWriter = new System.Web.UI.HtmlTextWriter(writer);
this.RenderControl(htmlWriter);//输出
HttpContext.Current.Response.Write(writer.ToString());
HttpContext.Current.Response.End();
}

另外在前台要加上 ValidateRequest="false" EnableEventValidation="false"

注意：在导出时，出现图片不能显示，记得要改为绝对路径
