public class RegistrationInformation
{
public RegistrationInformation()
{
//
//TODO: 在此处添加构造函数逻辑
//
}
    public struct RegistrationInformation
    {
        private string firstname;
        public string Firstname
        {
            get { return firstname; }
            set { firstname = value; }
        }
        private string lastname;
        public string Lastname
        {
            get { return lastname; }
            set { lastname = value; }
        }
        private string email;
        public string Email
        {
            get { return email; }
            set { email = value; }
        }
        private string selectedevent;
        public string SelectedEvent
        {
            get { return selectedevent; }
            set { selectedevent = value; }
        }
    }
}
以上是创建的类，
以下我在default_aspx类添加公共属性RegistrationInformation
public RegistrationInformation RegistrationInformation
    {
        get
        {
            RegistrationInformation ri = new RegistrationInformation();
            ri.-----
        }
    }
我发现照书上说ri应该有firstname和lastname等属性，但实际上没有，不知道我的代码错在那里
这一节是在入门经典3的500页，高人们帮忙看一下吧，不懂的地方可以看一下附件

那个不是结构呀,是类,结构在类里面,我觉得入门经典的代码有问题.

我怎么看到结构都写在类里面呢
