我需要C# 导出到word文档的代码，最好不用怎么修改就能用

System.IO.StringWriter SW = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter HTW=new System.Web.UI.HtmlTextWriter(SW);
Page.RenderControl(HTW);
//Page为要导出的对象,当前是Page,如果是DataGrid,DataList等都可以
Response.Buffer=true;
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = "Response.ContentType";
//Response.ContentType是输出流的 HTTP MIME 类型
//Response.ContentType --- word文件
//application/vnd.ms-excel --- excel文件
//...
Response.Charset="utf-8";
Response.ContentEncoding=System.Text.Encoding.GetEncoding("utf-8");
Response.AddHeader("Content-Disposition", "attachment;filename=XXX.doc");
//attachment --- 作为附件下载
//inline --- 在线打开
//filename如过是中文,则可以用HttpUtility.UrlEncode(fileName,System.Text.Encoding.UTF8)
//进行进行编码,以解决文件名乱码的问题
Response.Write(SW.ToString());
Response.Flush();
Response.Close();
