intouch代理

Ⅰ 怎麼設置webbrowser設置代理用戶名和密碼

var credentialStringValue = "user:pass";
var credentialByteArray = ASCIIEncoding.ASCII.GetBytes(credentialStringValue);
var credentialBase64String = Convert.ToBase64String(credentialByteArray);

Object nullObject = 0;
Object nullObjectString = "";
Object authObject = string.Format("Proxy-Authorization: Basic {0}{1}", credentialBase64String, Environment.NewLine);

browser.Navigate(args.Url, ref nullObject, ref nullObject, ref nullObjectString, ref authObject);
