Posting form content with the WebBrowser control

A while ago I was working on one of my many side projects and needed to be able to login to a website using a WebBrowser control. The form used Post rather then Get, so I wasn't able to simply append the appropriate form elements onto the URL.

I did some searching online and ended up with a nice little method to Post form content to a site by sending the correct headers in your Navigate call.

Code:

private void Post(string szUrl, string szPost)
{
    Encoding a = Encoding.UTF8;
    byte[] byte1 = a.GetBytes(szPost);
    webBrowser.Navigate(szUrl, szTarget, byte1,
"Content-Type: application/x-www-form-urlencoded\r\n");
    return;
}
