C# HTTP request/response

Question

Hello everyone,

 

I need to build up using C# HTTP Server (HTTP Listener, which could parse various HTTP fields, like post data and return response) and I also need to get an HTTP client which could package various HTTP fields (like URL, post data, etc.).

 

Are there any sample codes to recommend? I searched MSDN, failed to find any complete client and server samples. I have searched some other samples, which is built on TCP listener, and manually package/unpackage from TCP other than HTTP package level.

 

thanks in advance,
George

 

Answer 1

For client, WebClient should do everything you need. See MSDN:

 

http://msdn2.microsoft.com/en-us/library/system.net.webclient(VS.80).aspx

 

For server, easiest (for simple client/server) would be a "handler" (i.e. an ashx page) in asp.net; alternatively you can use HttpListener to create a basic server that can respond to requests; again see MSDN:

 

http://msdn2.microsoft.com/en-us/library/system.net.httplistener.aspx

Code Snippet

WebRequest request = WebRequest.Create("your url comes here with parameters and stuf like in IE");

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

Stream dataStream = response.GetResponseStream();

StreamReader reader = new StreamReader(dataStream);

string responseFromServer = reader.ReadToEnd();

reader.Close();

dataStream.Close();

response.Close();

Or...

 

Code Snippet

using (WebClient client = new WebClient())

{

    string responseFromServer = client.DownloadString("your url comes here with parameters and stuf like in IE");

}

 

I know which I'll go for... WebClient also offers a range of other methods and overloads for most common cases, such as sending a body, talking to files, etc...
