C# SSL Basic Access Authentication

Question

I want to request reports from a third party and they require "Basic Access Authentication" via POST:

Your client application must use Basic Access Authentication 
to send the user name and password.

Can someone point me in the right direction or recommend a tutorial on how to do this with C#?

Edit: I did see this post but there are two answers and I'm not sure if thats what I need to do or which one is the preferred method.

Answer 1

Assuming you use a WebRequest, you attach a CredentialCache to your request:

        NetworkCredential nc = new NetworkCredential("user", "password");
        CredentialCache cc = new CredentialCache();
        cc.Add("www.site.com", 443, "Basic", nc);


        WebRequest request = WebRequest.Create("https://www.site.com");
        request.Credentials = cc;
        request.PreAuthenticate = true;
        request.Method = "POST";

        // fill in other request properties here, like content

        WebResponse respose = request.GetResponse();
