Как отобразить в форме свойства подключения к БД?

private void Form1_Load(object sender, EventArgs e)
        {
            SqlConnectionStringBuilder conbuilder = new SqlConnectionStringBuilder();
            MessageBox.Show(conbuilder.AttachDBFilename);
        }

private void Form1_Load(object sender, EventArgs e)
        {
            SqlConnectionStringBuilder conbuilder = new SqlConnectionStringBuilder();
            MessageBox.Show(conbuilder.ConnectionString);
        }

private void Form1_Load(object sender, EventArgs e)
        {
            SqlConnectionStringBuilder conbuilder = new SqlConnectionStringBuilder("тут строка подключения");
            MessageBox.Show(conbuilder.AttachDBFilename);
        }

private void Form1_Load(object sender, EventArgs e)
        {
            SqlConnectionStringBuilder conbuilder = new SqlConnectionStringBuilder(@"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=C:\Users\Tim\source\repos\EmployeesList\EmployeesList\Database.mdf;Integrated Security=True");
            MessageBox.Show(conbuilder.AttachDBFilename);
        }
