C# 用于向网站提交和保存数据的HttpRequest Post方法

我正在尝试登录一个用户名密码必需的网站，并用httprequest-post方法向该网站提交一些数据。你可以认为这个网站就像一个需要先登录的博客网站。我想做的是先登录这个网站，然后进入发布部分，在这个网站的文本框中写一些东西，然后点击提交按钮发布我写的东西

到目前为止，我可以使用http get方法登录此网站，并从该get方法响应中获取所需的viewstate、eventValidation值和Cookie，并使用我的用户名和密码在我的post方法的postData中使用它们，然后我可以登录。然后我也可以使用cookies进入发布部分，我也可以从前面的get方法获得cookies。但当我尝试在本节中编写一些内容并单击发布（我使用telerik fiddler跟踪网站流量）时，我的post方法似乎需要两个值：“RadStyleSheetManager1_TSSM”和“RadScriptManananer_TSM”。以下是从telerik fiddler获取的post数据：

正如您所看到的，post数据太长，但我认为失败的原因是我无法捕获“RadStyleSheetManager1_TSSM”和“RadScriptManananer_TSM”值。使用post方法提交某些数据需要两个值，还是我做错了其他事情

下面是我的主代码和主代码中使用的http post方法。谢谢你的帮助

注：我是这个网站的新手，所以如果我不能充分告知我的问题，请警告我。我真的很想实现这个职位的事情

POST方法

       public static string Post(string url, string referer, string postData, CookieContainer cookies, string contentType, string accept)
    {
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
        req.Method = "POST";
        req.CookieContainer = cookies;
        req.Referer = referer;
        req.UserAgent = "";
        req.ContentType = contentType;
        req.Accept = accept;
        req.ContentLength = postData.Length;

        Stream postStream = req.GetRequestStream();
        byte[] postBytes = Encoding.ASCII.GetBytes(postData);
        postStream.Write(postBytes, 0, postBytes.Length);
        postStream.Dispose();

        HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
        cookies.Add(resp.Cookies);
        StreamReader reader = new StreamReader(resp.GetResponseStream());
        string src = reader.ReadToEnd();
        reader.Dispose();          

        return (src);

这是网站发布部分的源代码。如您所见，“RadStyleSheetManager1_TSSM”和“RadScriptManananer_TSM”的值为空，因此我无法捕捉它

可能是错误的MIME类型导致了故障：

“application/x-www-form-urlencoded”

看起来有多余的空格。使其成为

“application/x-www-form-urlencoded”

注意，类已经过时，请改用。噢，非常感谢，我没有看到多余的空格。您为我节省了很多时间。可能是错误的MIME类型导致了故障：
