WebRequest/WebResponse Memory leak

Question

I have an .Net Framework #4.0 application that makes a large number of web requests using the WebRequest/WebResponse classes , as i see it has memory leak (or maybe i am doing something wrong) I Wrote some small simple application that demonstrates this: ``` class Program { public static void Main(string[] args) { while(true) { var webRequest = (HttpWebRequest)WebRequest.Create("http://www.gooogle.com"); Init(webRequest); using (var webResponse = (HttpWebResponse)webRequest.GetResponse()) { var responseStream = webResponse.GetResponseStream(); responseStream.ReadTimeout = 30; var streamReader = new StreamReader(responseStream, Encoding.UTF8); var page = streamReader.ReadToEnd(); streamReader.Close(); streamReader.Dispose(); responseStream.Close(); responseStream.Dispose(); webResponse.Close(); Console.WriteLine("Done"); //GC.Collect(); } } } private static void Init (HttpWebRequest webRequest) { webRequest.Method = "GET"; webRequest.Host = "www.gooogle.com"; webRequest.UserAgent = "Mo…

Accepted Answer

You're allocating memory in a tight loop. You probably don't have a memory leak, you have a poorly behaved application (in the sense that it's using up lots of system resources for no reason.)

The garbage collector is not going to interrupt your loop in order to compact freed memory unless it has to due to memory pressure. The simple fix would be to introduce a delay between iterations of the loop (could be as simple as Thread.Sleep, though I don't recommend that.)

Once your program is not working so hard to consume all available CPU time it should allow the GC to run more frequently.
