Multiple HTTP request in C#

Question

I need to send about 200 HTTP requests in parallel to different servers and get response. I use HttpWebRequest class in C#. But I don\'t see good time enhancement when requests

Answer 1

This is the code of android application of sending the request. How can we use the upper code like:

params.add(new BasicNameValuePair("key", "value");
HttpPost request = new HttpPost();
List params = new ArrayList();
params.add(new BasicNameValuePair("key", "value");// How can we give the value in this format format
post.setEntity(new UrlEncodedFormEntity(params));

httpClient.execute(request);
