问题 I build this method (c#) in order to receive the HTTP response status code from an URL. whene I run this method ones it's works fine, but when I run it in a loop, the third time its stuck. any clue?? public static string isAlive(string url) { Console.WriteLine("start: Is Alive Test"); WebRequest request = WebRequest.Create(url); try { HttpWebResponse response = (HttpWebResponse)request.GetResponse(); return Convert.ToString((int)response.StatusCode); } catch(WebException ex) { HttpWebResponse

问题 I tried to search previous discussion about this issue but I didn't find one, maybe it's because I didn't use right keywords. I am writing a small program which posts data to a webpage and gets the response. The site I'm posting data to does not provide an API. After some Googling I came up to the use of HttpWebRequest and HttpWebResponse. The code looks like this: HttpWebRequest httpRequest = (HttpWebRequest)WebRequest.Create("https://www.site.com/index.aspx"); CookieContainer cookie = new

问题 What's the optimal buffer size to use with a stream from HttpWebResponse.GetResponseStream()? Online examples vary from 256b to as much as 5Kb. What gives? I guess buffer sizes might be situational. If so what are the situations to use what type of buffer size? Thanks. 回答1: Really, it doesn't matter very much. Sure, if you use really small buffers, you may have to make a few extra calls down through the layers to get the bytes (though the stream is likely doing at least some buffering -- I

问题 I have a few HttpWebRequests and HttpWebResponses chained together, also using CookieContainer. The code simulates a user going through three different 'I agree' pages which set the cookie info, logging in with username and password on a fourth, and doing a POST (search) on the fifth returning the response as a string. Is there a way I can maintain the HttpWebRequest object as 'logged in' to avoid going through those steps each time any user performs a search? Can I set it up as static, and

问题 How to use HttpWebRequest and HttpWebResponse to create a webservice and how will the request and responses will be send across the wire? 回答1: this is the syntax for using HttpWebRequest and HttpWebResponse WebRequest _request; string text; string url = "UrlToGet"; _request = (HttpWebRequest)WebRequest.Create(url); using (WebResponse response = _request.GetResponse()) { using (StreamReader reader =new StreamReader(response.GetResponseStream())) { text = reader.ReadToEnd(); } } 回答2:
