向高手请教一个关于导出到Word的问题
我用下面这种方式将页面导出到Word时背景图片导不出来是怎么回事？ 
string fileName = string.Empty;
  if (string.IsNullOrEmpty(fileName))
  {
  fileName = "著作工作量分配单";
  }
  System.IO.StringWriter sw = new System.IO.StringWriter();
  HtmlTextWriter htw = new HtmlTextWriter(sw);
  this.Page.Form.RenderControl(htw);
  string pageHtml = sw.ToString();
  int startIndex = pageHtml.IndexOf("<div id=\"Print\"");
  int endIndex = pageHtml.LastIndexOf("</div>");
  int lenth = endIndex - startIndex;
  pageHtml = pageHtml.Substring(startIndex, lenth);
  pageHtml = pageHtml.Remove(pageHtml.LastIndexOf("<div>"));
  HttpContext context = HttpContext.Current;
  context.Response.AppendHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8) + ".doc");
  context.Response.ContentType = "application/ms-word";
  context.Response.ContentEncoding = System.Text.Encoding.UTF8;
  context.Response.Charset = "UTF8";
  context.Response.Write(pageHtml);
  context.Response.End();
