I have a problem in a same namespace:





public partial class frmForm1 : Form  // Form1
        {
     public class Account
            {
                public string Username;
                public string Password;
                public string RePassword;
                public string Name;
                public string bd;
                public string dt;
                public string dc;

            }

            public class ListAcc
            {
                public static int count = 0;
                private static List<Account> UserList;
                public static List<Account> Data()
                {
                    return UserList;
                }
            }
    }


 public partial class frmForm2 : Form  // Form2
    {

        private void button2_Click(object sender, EventArgs e)
        {
            ListAcc A;   // error
            string n = A<Account>[0].Usename; // error
            // What should i do?
        }
    }
