本文深入探讨了在网页开发中利用StringBuilder, StringWriter, HtmlTextWriter和Page类进行高效渲染的方法，包括事件验证的禁用、初始化设计者代码以及将页面内容导出为Excel文件的过程。
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;
// Deshabilitar la validación de eventos, sólo asp.net 2
page.EnableEventValidation = false;
// Realiza las inicializaciones de la instancia de la clase Page que requieran los diseñadores RAD.
page.DesignerInitialize();
page.Controls.Add(form);
form.Controls.Add(GridView1);
page.RenderControl(htw);
Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "attachment;filename=data.xls");
Response.Charset = "UTF-8";
Response.ContentEncoding = Encoding.Default;
Response.Write(sb.ToString());
Response.End();
StringWriter sw = new StringWriter(sb);HtmlTextWriter htw = new HtmlTextWriter(sw);Page page = new Page();HtmlForm form = new HtmlForm();GridView1.EnableViewState = false;// Deshabilitar la validación de eventos, sólo asp.net 2page.EnableEventValidation = false;
