C＃-Webclient發布數據

Question

我試圖在此處復制網站帖子： https : //www.usbank.com/cgi_w/cfm/personal/products_and_services/reoPropertiesReq.cfm

我只想發布任何狀態以查看結果，因為它們最終將以電子郵件形式發送。 這是我的發布方法，可以在其他網站上登錄等，所以我知道它可以工作

public HtmlDocument POST(string url, string postData)
    {//string myParameters = "param1=value1&param2=value2&param3=value3";

        HtmlDocument hdoc = new HtmlDocument();
        wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
        using (wc)
        {
            hdoc.LoadHtml(wc.UploadString(url, postData));
        }

        return hdoc;
    }

我像這樣使用它：

HtmlDocument mainDoc = POST("https://www.usbank.com/cgi_w/cfm/personal/products_and_services/reoPropertiesReq.cfm",
            "selState=4&StateNM=Arizona");

但這似乎不正確。 誰能分析這個網站並確定它是我的代碼還是丟失的數據？

我前一段時間已經為我編寫了此功能，希望對您有所幫助

    private void POST(string url, string data)
    {
        HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(new Uri(url));
        req.Method = "POST";
        req.Headers.Add(HttpRequestHeader.AcceptLanguage, "de-DE,de;q=0.8,en-US;q=0.7,en;q=0.3");

        req.Timeout = req.ReadWriteTimeout = 15000;

        ASCIIEncoding encoding = new ASCIIEncoding();
        byte[] dataBytes = encoding.GetBytes(data);
        req.ContentLength = dataBytes.Length;
        Stream stream = req.GetRequestStream();
        stream.Write(dataBytes, 0, dataBytes.Length);
        stream.Close();

        req.GetResponse();
    }
