webclient - 使用 WebClient 时尝试了太多自动重定向错误消息

Question

这是我写的代码。

        NameValueCollection values = new NameValueCollection();
        values.Add("ctl00$ContentPlaceHolder1$ctrl9$txtDate1", "01.01.2012");
        values.Add("ctl00$ContentPlaceHolder1$ctrl9$txtDate2", "26.11.2012");
        values.Add("ctl00$ContentPlaceHolder1$ctrl9$cmbSymbol", "DHP");

        using (WebClient client = new WebClient())
        {
            client.Headers.Add("ContentType","application/x-www-form-urlencoded");
            client.Headers.Add("Cookie","ASP.NET_SessionId");
            client.Headers.Add("userAgent","Opera/9.80 (Windows NT 5.1) Presto/2.12.388 Version/12.16");
            client.Headers.Add("Host","www.mse.mk");
            client.Headers.Add("Accept","text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/webp, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1");
            client.Headers.Add("KeepAlive","true");
            byte[] result = client.UploadValues("Some Url", "POST", values);
        }

但是当我运行这段代码时，我得到了异常“尝试了太多自动重定向”。所以我的问题是错误在哪里以及如何解决它。

谢谢
