How to set Accept and Accept-Language?

I want to upload a file (RFC 1867) and need to create a request like this:

POST /test-upload.php.xml HTTP/1.1
Host: example.com
User-Agent: Mozilla/5.0 (Windows NT 5.2; WOW64; rv:2.0.1) Gecko/20100101 Firefox/4.0.1
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Keep-Alive: 115
Connection: keep-alive

Take a look at Accept property:

HttpWebRequest myHttpWebRequest=(HttpWebRequest)WebRequest.Create(myUri);
myHttpWebRequest.Accept="image/*";    
HttpWebResponse myHttpWebResponse=
         (HttpWebResponse)myHttpWebRequest.GetResponse();

This MSDN article shows how to add custom headers to your request:

//Get the headers associated with the request.
WebHeaderCollection myWebHeaderCollection = myHttpWebRequest.Headers;    

//Add the Accept-Language header (for Danish) in the request.
myWebHeaderCollection.Add("Accept-Language:da");

//Include English in the Accept-Langauge header. 
myWebHeaderCollection.Add("Accept-Language","en;q=0.8");
