如何在系统中设计两种类型的账户
我正在尝试为学生和教师创建一个社交网络应用程序。 我目前正在设计用户帐户模块
我想到了这两种方法
方法1
Public class Account
{
public string AccountId{get;set;}
public string AccountName{get;set;}
.
.
.
}
public class Student : Account
{
public Course[] Courses {get; set;}
//other student properties
.
.
.
}
public class Teacher : Account
{
//other teacher properties
}
方法2
Public class Account
{
public string AccountId{get;set;}
public string AccountName{get;set;}
public AccountType AccountType {get;set;} //AccontType is enum having student and teacher
.
.
.
}
public class User
{
public string UserId { get;set;}
public string UserName {get;set;}
public Account Account {get;set;}
}
public class Student : User
{
public Course[] Courses {get; set;}
//other student properties
.
.
.
}
public class Teacher : User
{
//other teacher properties
}
有没有比这些方法更好的方法？
I am trying to create a social networking application for students and teachers.
I am currently designing the user accounts module
I have thought of these two approaches
Approach 1
Public class Account
{
public string AccountId{get;set;}
public string AccountName{get;set;}
.
.
.
}
public class Student : Account
{
public Course[] Courses {get; set;}
//other student properties
.
.
.
}
public class Teacher : Account
{
//other teacher properties
}
Approach 2
Public class Account
{
public string AccountId{get;set;}
public string AccountName{get;set;}
public AccountType AccountType {get;set;} //AccontType is enum having student and teacher
.
.
.
}
public class User
{
public string UserId { get;set;}
public string UserName {get;set;}
public Account Account {get;set;}
}
public class Student : User
{
public Course[] Courses {get; set;}
//other student properties
.
.
.
}
public class Teacher : User
{
//other teacher properties
}
Is there any better approach than these approaches?

我认为方法 2 更加清晰，也是首选。
归根结底是
用户是否拥有帐户或者是用户帐户？对我来说是前者，在这种情况下您应该使用组合而不是继承，就像在方法 2 中所做的那样。Approach 2 is much clearer and preferred in my opinion.
What it comes down to is does a
Userhave an account or is aUseran account? For me its the former and you should use composition instead of inheritance in this case as you do in approach 2.我更喜欢方法 2，因为它更接近现实世界的场景。学生和教师都是用户，他们每个人都拥有一个帐户并设置了所需的属性。
I like approach 2 better because it's more closer to the real world scenario. Students and Teachers are users and each of them have an account with the desired properties set.
