我想将gridview导出到powerpoint。我有以下代码。但我有以下问题：
当我将它用于 ms office 2010.it 时出现错误：
Powerpoint 无法读取 c:\users\filename.ppt。无法打开演示文稿。您的防病毒程序可能会阻止您打开演示文稿。要解决此问题，请确保您的防病毒程序是最新的并且工作正常。如果问题仍然存在并且演示文稿来自您信任的人，请关闭您的防病毒程序，然后再次尝试打开演示文稿。如果这样做，请确保在打开演示文稿后再次打开防病毒程序。
当我将它用于 ms office 2007 时，它打开但没有 gridview
代码：
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=FileName.ppt");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Charset = "";
// this.Response.ContentType = "application/vnd.openxmlformats- officedocument.presentationml.presentation";
this.Response.ContentType = "application/vnd.ms-powerpoint.presentation.macroEnabled.12";
this.Response.ContentType = "application/vnd.ms-powerpoint";
//Response.ContentType = "application/vnd.ppt";
GridView2.AllowPaging = false;
GridView2.DataBind();
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
GridView2.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
Response.Flush();
