Hi I want to post data using System.Net.Webrequest in the form of Querystring Is it Possible ? If yes then can anybody give me the code for that

推荐答案

的代码当然可以.从客户端的角度来看，没有查询字符串之类的东西.这只是URL的一部分. 这项工作看起来很有趣，可以很好地处理查询参数: WebRequest参数实用工具 [ ^ ].

Of course it is possible. From the client stand point, there is no such thing as query string; this is just part of the URL. This work looks like an interesting supplement to handle query arguments nicely: WebRequest Parameter Utility[^].

在这里，我们去.. Here we go.. using System.Net; using System.IO; public string Post(string url, string data) { string vystup = null; try { //Our postvars byte[] buffer = System.Text.Encoding.ASCII.GetBytes(data); //Initialisation, we use localhost, change if appliable HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create(url); //Our method is post, otherwise the buffer (postvars) would be useless WebReq.Method = "POST"; //We use form contentType, for the postvars. WebReq.ContentType = "application/x-www-form-urlencoded"; //The length of the buffer (postvars) is used as contentlength. WebReq.ContentLength = buffer.Length; //We open a stream for writing the postvars Stream PostData = WebReq.GetRequestStream(); //Now we write, and afterwards, we close. Closing is always important! PostData.Write(buffer, 0, buffer.Length); PostData.Close(); //Get the response handle, we have no true response yet! HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse(); //Now, we read the response (the string), and output it. Stream Answer = WebResp.GetResponseStream(); StreamReader _Answer = new StreamReader(Answer); vystup = _Answer.ReadToEnd(); //Congratulations, you just requested your first POST page, you //can now start logging into most login forms, with your application //Or other examples. } catch (Exception ex) { } return vystup.Trim() + "\n"; } Post("www.xyz","postvar=1&postvar=2")
