一页只能有一个服务器端 Form 标记,不是一般问题!

[葫芦的世界]

我现在能够确认我的ASPX页面中只包含有一个:<Form runat="server">
可是运行出现以下错误:
System.Web.HttpException: 一页只能有一个服务器端 Form 标记
CS代码:
Response.Clear();
Response.Buffer= true;
Response.Charset="gb2312";
Response.AppendHeader("Content-Disposition","attachment;filename=FileFlow.xls");
Response.ContentEncoding=System.Text.Encoding.GetEncoding("gb2312");
Response.ContentType = "application/ms-excel";
this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
oStringWriter.WriteLine("联系人姓名,手机号码);
SqlDataReader dr = DBHelper.ExecuteReader(sql);
while (dr.Read())
{
oStringWriter.WriteLine(dr["zhName"].ToString() + "," + dr["mobile"].ToString()
}
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

//就是下面这一行,只要在这里设置断点(Response.End()),页面上就可以弹出保存窗口,也就是说不会出错错误.

this.RenderControl(oHtmlTextWriter);

//在这里设置断点(Response.End()),就会出现
//System.Web.HttpException: 一页只能有一个服务器端 Form 标记 错误

Response.Write(oStringWriter.ToString());
Response.End();

以下代码成功.谢谢楼上的各位!
HttpResponse resp;
resp = Page.Response;
resp.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
resp.AppendHeader("Content-Disposition", "attachment;filename=filename.xls");
Response.ContentType = "application/text/csv";

System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
oStringWriter.WriteLine("联系人姓名,手机号码,电子邮件,公司,职位");
resp.Write(oStringWriter);
resp.End();
