1. Submit binary Stream data (in JSON format):

          varDIC =Newsorteddictionary<string,string>            {                {"name","Test"},                {"Pass","123"},            }; //Serialization Parameters            varJsonparam =Jsonconvert.serializeobject (DIC); //Send Request            varRequest =(HttpWebRequest) webrequest.create (URL); Request. Method="POST"; Request. ContentType="Application/json;charset=utf-8"; varBytedata =Encoding.UTF8.GetBytes (Jsonparam); varLength =bytedata.length; Request. ContentLength=length; varwriter =request.            GetRequestStream (); Writer. Write (Bytedata,0, length); Writer.            Close (); //Receive Data            varResponse =(HttpWebResponse) request.            GetResponse (); varResponsestring =NewStreamReader (response. GetResponseStream (), Encoding.GetEncoding ("Utf-8")). ReadToEnd ();

2. Submit Form Method One:

            varURL ="xxxxxxxxxxxxxxxxxxxxxx"; varWebclientobj =NewWebClient (); varPostvars =NewNameValueCollection {{"name","Test"},                {"Pass","123"}            }; byte[] byremoteinfo = webclientobj.uploadvalues (URL,"POST", Postvars); stringJSON = Encoding.UTF8.GetString (byremoteinfo);

3, submit the form method two:

varURL ="xxxxxxxxxxxxxxxxxxxxxxx"; //by grasping the package tool, you can see that this is the format            varPostData ="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 ();
