驗證網站的憑證

Question

我有一個網站：「https://blahblah.com」

爲了驗證它，我這樣做（工作正常）：

NetworkCredential credentials = new NetworkCredential(); 
      credentials.UserName = AppVars.Username; 
      credentials.Password = AppVars.Password; 

      HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
      request.Credentials = credentials; 
      //..... 

但我怎麼如果我想要添加登錄功能，只需驗證用戶名和密碼？

更新的代碼：

private void btnLogIn_Click(object sender, EventArgs e) 
     { 
      Properties.Settings.Default.Username = txtUserName.Text; 
      Properties.Settings.Default.Password = txtPassword.Text; 

      using (PrincipalContext pc = new PrincipalContext(ContextType.Domain, AppVars.ixLibraryConnectionTestURL)) 
      { 
       try 
       { 
        bool isValid = false; 
        isValid = pc.ValidateCredentials(AppVars.Username, AppVars.Password); 
        if (isValid == true) 
        { 
         //just testing 
         MessageBox.Show("is valid"); 
        } 
        else 
        { 
         //just testing 
         MessageBox.Show("is not valid"); 
        } 
       } 
       catch (Exception ex) 
       { 
        MessageBox.Show(ex.Message); 
       } 
      }  
     } 

域名看起來是這樣的：https://xxxxxx-services.zzz999.org/pqg_4/lib/api/sdo/rest/v1

用途：System.DirectoryServices.AccountManagement命名空間

// create a "principal context" - e.g. your domain (could be machine, too) 

using(PrincipalContext pc = new PrincipalContext(ContextType.Domain, "YOURDOMAIN")) 
{  

// validate the credentials  
bool isValid = pc.ValidateCredentials("myuser", "mypassword"); 
}
