使用Windows窗体对C#中的本地MS SharePoint 2013网站进行远程/活动/基于声明的身份验证

如何使用Windows窗体对C#中的本地MS SharePoint 2013网站进行远程/活动/基于声明的身份验证？请注意，我是SharePoint 2013应用程序开发人员的新手，因此我将感谢有关如何完成此任务的清晰而简单的步骤。

这是另一次尝试，但没有运气

  private void btnLogin_Click(object sender, EventArgs e)
    {
        try
        {
            string webUrl = textBox1.Text;

            string userName = txtBxUN.Text;
            string password = txtBxPW.Text;
            using (var context = new ClientContext(webUrl))
            {
                var secure = new SecureString();
                foreach (char c in password)
                {
                    secure.AppendChar(c);
                }
                // get error the 'username' argument is invalid when i try to login to on-premises SharePoint 2013 website 
                context.Credentials = new SharePointOnlineCredentials(userName, secure);
                context.Load(context.Web, w => w.Title);
                context.ExecuteQuery();
                MessageBox.Show("Your site title is: " + context.Web.Title);
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }

 var dc = new subsiteDataContext(new Uri("http://.../subsite/_vti_bin/ListData.svc"))
            {
                Credentials = System.Net.CredentialCache.DefaultCredentials
            };
