Is there a popular C # library for working with HTTP? For example, simplification of work with httpwebrequest, etc.

For example, downloading an HTTP file with some parameters requires a lot of lines and knowledge of the format of the contents of the Http protocol, etc. WebClient itself does not.

So, being new, is there a well-known library that C # developers use here?

thanks

- : application/x-www-form-urlencoded multipart/form-data.

WebClient -. /x -www-form-urlencoded , , NameValueCollection. multipart/form-data, AFAIK, ( , ).

/-WWW--urlencoded

NameValueCollection formData = new NameValueCollection();
formData["q"] = "c# webclient post urlencoded";
formData["btnG"] = "Google Search";
formData["hl"] = "en";

WebClient myWebClient = new WebClient();
myWebClient.UploadValues(uriString, formData);

WebClient.UploadValues ​​ HTTP "POST", Content-Type - "application/x-www-form-urlencoded", URL- formData uriString.

Chilkat.HttpRequest req = new Chilkat.HttpRequest();
Chilkat.Http http = new Chilkat.Http();

bool success;

//  Any string unlocks the component for the 1st 30-days.
success = http.UnlockComponent("Anything for 30-day trial");
if (success != true) {

//  Build an HTTP POST Request:

req.AddParam("arg1","This is the value for arg1.");
req.AddParam("arg2","This is the value for arg2.");
req.AddParam("arg3","This is the value for arg3.");

//  Send the HTTP POST and get the response.  Note: This is a blocking call.
//  The method does not return until the full HTTP response is received.
