将html导出为word，只需要将header修改一下就可以了，代码如下：
Response.AppendHeader("Content-Disposition","attachment;filename=result.doc");
Response.ContentType = "application/ms-word";
Response.Charset = "UTF-8";
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.Write("<html xmlns:v=\"urn:schemas-microsoft-com:vml\" xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:w=\"urn:schemas-microsoft-com:office:word\" xmlns:m=\"http://schemas.microsoft.com/office/2004/12/omml\" xmlns=\"http://www.w3.org/TR/REC-html40\">");
Response.Write("<p>网页内容</p>");
Response.Write("</html>");
Response.End();
注：不加上黄色标注的部分，office打开后会出现html源代码。
