通过html给xls赋值，并下载xls文件

一、this.Response.Write(sw.ToString());System.IO.StringWriter sw = new System.IO.StringWriter();

this.Response.Clear();
            string strFileName;
            strFileName = "报表" + ".xls";
            Response.Buffer = true;
            Response.ContentType = "application/x-zip-compressed";
            Response.AddHeader("Accept-Language", "zh-cn");
            Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpContext.Current.Server.UrlEncode(strFileName));

System.IO.StringWriter sw = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(sw);

this.gvMutiQueResult.AllowPaging = false;
            if (Session["QueryResult"] != null)
            {
                this.gvMutiQueResult.DataSource = (DataTable)Session["QueryResult"];
                this.gvMutiQueResult.DataBind();
            }
            else
            {
                BindGV(); 绑定数据
            }

this.gvMutiQueResult.RenderControl(htmlWrite);
            this.Response.Write(sw.ToString());
            this.Response.End();
            Response.Write("<script type='text/javascript'>window.history.back();</script>");

二、Response.Write(html2Excel);string html2Excel

string strHtml; string fileName;

Response.Clear();
            Response.AddHeader("content-disposition", "attachment;filename=\"" + HttpUtility.UrlEncode(fileName) + ".xls\"");
            Response.ContentType = "application/ms-excel";

string html2Excel = "<html xmlns:x=\"urn:schemas-microsoft-com:office:excel\"><head><meta content=\"text/html;charset=UTF-8\" http-epuiv=\"content-type\">"
                +
                 string.Format(@"<!--[if gte mso 9]><xml>
            <x:ExcelWorkbook>
                <x:ExcelWorksheets>
                    <x:ExcelWorksheet>
                        <x:Name>{0}</x:Name>
                        <x:WorksheetOptions>
                            <x:Print>
                                <x:ValidPrinterInfo />
                            </x:Print>
                        </x:WorksheetOptions>
                    </x:ExcelWorksheet>
                </x:ExcelWorksheets>
            </x:ExcelWorkbook>
        </xml>
        <![endif]-->", fileName)
                 + "</head><body>"
                + strHtml +
                "</body></html>";

Response.Write(html2Excel);
            Response.End();

三、

//获取数据
                IDataBase sDB = DBFactory.GetDBInstance();
                DataTable dt = sDB.GetDataTable("select * from 表 where ID='" + ID.ToString() + "'");
                //输出
                if (dt.Rows.Count > 0)
                {

string DocFileName = dt.Rows[0]["DocFileName"].ToString();
                    string DocSize = dt.Rows[0]["DocSize"].ToString();
                    byte[] DocContent = (byte[])dt.Rows[0]["DocContent"];

Response.Clear();
                    Response.ClearHeaders();
                    Response.Buffer = false;
                    //string ContentType = dt.Rows[0]["DocType"].ToString();
                    Response.ContentType = "application/octet-stream";
                    Response.AddHeader("Content-Disposition", "attachment; filename=\"" + HttpUtility.UrlEncode(DocFileName, System.Text.Encoding.UTF8) + "\"");
                    Response.AddHeader("Content-Length", DocSize.ToString());
                    Response.BinaryWrite(DocContent);
                    Response.Flush();
                    Response.End();

}

四、Response.WriteFile(DownloadFile.FullName); System.IO.FileInfo DownloadFile = new System.IO.FileInfo(strFileName);

//下载开机提醒安装程序 rar
        private void DownloadDocument()
        {
            try
            {
                string strFileName = Server.MapPath("../../help/BootAlert.rar");
                System.IO.FileInfo DownloadFile = new System.IO.FileInfo(strFileName);
                Response.Clear();
                Response.ClearHeaders();
                Response.Buffer = false;
                Response.ContentType = "application/ms-excel";
                Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(strFileName, System.Text.Encoding.UTF8));
                Response.AppendHeader("Content-Length", DownloadFile.Length.ToString());
                Response.WriteFile(DownloadFile.FullName);
                Response.Flush();
                Response.End();
            }
            catch (Exception err)
            {
                throw err;
            }
        }

五、 byte[] binaryContent  Response.BinaryWrite(binaryContent);

newFileName = newFileName.Replace("\\\\", "\\").Replace("\\", "/");
                string outputFileName = newFileName.Substring(newFileName.LastIndexOf('/') + 1);
                byte[] binaryContent = System.IO.File.ReadAllBytes(newFileName);
                Response.Clear();
                Response.ClearHeaders();
                Response.Buffer = false;
                Response.ContentType = "application/octet-stream";
                Response.AddHeader("Content-Disposition", "attachment; filename=\"" + HttpUtility.UrlEncode(outputFileName, System.Text.Encoding.UTF8) + "\"");
                Response.AddHeader("Content-Length", binaryContent.Count().ToString());
                Response.BinaryWrite(binaryContent);
                Response.Flush();
                Response.End();

六、Response.TransmitFile(strFilePath, 0, fileSize);long fileSize = info.Length

FileInfo info = new FileInfo(strFilePath);
                    long fileSize = info.Length;
                    Response.Clear();
                    Response.Buffer = true;
                    Response.ContentType = "application/x-zip-compressed";
                    Response.AddHeader("Accept-Language", "zh-cn");
                    Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpContext.Current.Server.UrlEncode(info.Name));
                    //不指明Content-Length用Flush的话不会显示下载进度   
                    Response.AddHeader("Content-Length", fileSize.ToString());
                    Response.TransmitFile(strFilePath, 0, fileSize);
                    Response.Flush();
                    Response.Close();
                    info.Delete();
