How to simulate browser HTTP POST request and capture result in C#
You could take a look at the WebClient class. It allows you to post data to an arbitrary url:
using (var client = new WebClient())
{
var dataToPost = Encoding.Default.GetBytes("param1=value1¶m2=value2");
var result = client.UploadData("http://example.com", "POST", dataToPost);
// do something with the result
}
Will generate the following request:
POST / HTTP/1.1
Host: example.com
Content-Length: 27
Expect: 100-continue
Connection: Keep-Alive
param1=value1¶m2=value2
