1、提交二進位流資料（json格式）：

          var dic = new SortedDictionary<string, string>            {                {"name", "test"},                {"pass", "123"},            };                        //序列化參數            var jsonParam = JsonConvert.SerializeObject(dic);            //發送請求            var request = (HttpWebRequest)WebRequest.Create(Url);            request.Method = "POST";            request.ContentType = "application/json;charset=UTF-8";            var byteData = Encoding.UTF8.GetBytes(jsonParam);            var length = byteData.Length;            request.ContentLength = length;            var writer = request.GetRequestStream();            writer.Write(byteData, 0, length);            writer.Close();            //接收資料            var response = (HttpWebResponse)request.GetResponse();            var responseString = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8")).ReadToEnd();

 

2、提交表單方法一：

            var url = "xxxxxxxxxxxxxxxxxxxxxx";            var webClientObj = new WebClient();            var postVars = new NameValueCollection {                {"name", "test"},                {"pass", "123"}            };            byte[] byRemoteInfo = webClientObj.UploadValues(url, "POST", postVars);            string json = Encoding.UTF8.GetString(byRemoteInfo);

3、提交表單方法二：

var url = "xxxxxxxxxxxxxxxxxxxxxxx";            //通過抓包工具，可以看到是這個格式            var postData = "username=test&password=123";            HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);            req.Method = "POST";            req.Timeout = 30000;            req.AllowAutoRedirect = false;            req.ContentType = "application/x-www-form-urlencoded";            req.KeepAlive = true;            byte[] postBytes = Encoding.UTF8.GetBytes(postData);            req.ContentLength = postBytes.Length;            Stream postDataStream = req.GetRequestStream();            postDataStream.Write(postBytes, 0, postBytes.Length);            postDataStream.Close();            HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
