asp.net 如何输出 Word.Document oDoc导出前台word

[efreer4]

我用程序创建好了 Word.Document oDoc 对象，如何，用户点按钮，前台弹出保存对话框？？
而不是保存到服务器上，然后导出

protected void btnDownLoad_Click(object sender, EventArgs e)
{
System.IO.StringWriter SW = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter HTW = new System.Web.UI.HtmlTextWriter(SW);
labRep.RenderControl(HTW);//labReg为一Label标签
Response.Buffer = true;
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = "application/msword";
Response.Charset = "gb2312";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
Response.AddHeader("Content-Disposition", "attachment;filename=任务报告.doc");
Response.Write(SW.ToString());
Response.Flush();
Response.Close();
}
