c# - POST to my localhost on port 5587 -

i want able write code interacts app running on computer listening on port 5587.

static void main(string[] args) {     httppost("http://localhost:5587", "/send/?username=testingname&password=testingpw"); }  public static string httppost(string uri, string parameters) {     system.net.webrequest req = system.net.webrequest.create(uri);     req.proxy = webrequest.defaultwebproxy;     //add these, we're doing post     req.contenttype = "application/x-www-form-urlencoded";     req.method = "post";     //we need count how many bytes we're sending. params should name=value&     byte[] bytes = system.text.encoding.ascii.getbytes(parameters);     req.contentlength = bytes.length;     system.io.stream os = req.getrequeststream();     os.write(bytes, 0, bytes.length); //push out there     os.close();     system.net.webresponse resp = req.getresponse();     if (resp == null) return null;     system.io.streamreader sr = new system.io.streamreader(resp.getresponsestream());     resp.close();      return sr.readtoend().trim(); } 

when read specs on app, says:

1) post request should be:

http://host:port/send/? username=user& password=pw& to=destination& bcc=bccdestination& subject=messagesubject

2) , post data should be:

message=messagebody

3) also, post request returns uuid of message in queue. uuid used later checking status of messages in queue.

how might change code pull off 3 things there need including getting response id can save later?

---

edit:

there screen shot of output need looks versus output putting out.

the query string parameters should part of uri string, , message needs set in request body

call this

string uuid = httppost("http://localhost:5587/send/?username=user&password=pw&to=destination&bcc=bccdestination&subject=messagesubject", "message=hi there"); console.writeline(uuid); console.readline(); 

change last 2 lines of httppost method to

string uuid = sr.readtoend().trim(); resp.close();  return uuid; 

of course need change parameters values valid
