Currently im studying the C# with ASP.NET MVC 4 with Code First Approach. Im Visual Basic Developer, and Now i want to Start C#. And, now i came accross the situation where i've to manage Multiple Inheritance. But, it is not possible with Class i thought. So, how should i manage these classes i have :
//I have the Following Person Class which Hold Common Properties
//and a Type of Person e.g : Student, Faculty, Administrative
public class Person
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Type { get; set; }
}
//This is my Student Class, which is Derived from Person
public class Student : Person
{
public DateTime DateOfBirth { get; set; }
public DateTime EnrollmentDate { get; set; }
public string Remarks { get; set; }
public bool Approved { get; set; }
public DateTime ApprovedDate { get; set; }
public int ApprovedUserId { get; set; }
}
//This is my Faculty Class, which is also Derived from Person
public class Faculty : Person
{
public DateTime HiredDate { get; set; }
public bool Approved { get; set; }
public DateTime ApprovedDate { get; set; }
public int ApprovedUserId { get; set; }
}
What I want to Make is Approved, ApprovedDate, and ApprovedUserId also common. I want to Specify those Properties like :
public class Approve {
public bool Approved { get; set; }
public DateTime ApprovedDate { get; set; }
public int ApprovedUserId { get; set; }
}
And, want to use like :
public class Student : Person, Approve
{
public DateTime DateOfBirth { get; set; }
public DateTime EnrollmentDate { get; set; }
public string Remarks { get; set; }
}
And, i cannot put those things inside PERSON. Because, i've to use this to another classes to, but those are not Person.
Then, how do i achieve this...
Please give me an Example for the Above Situation.
Please Help. And, Thank You so much in Advance.
One possible solution would be to modify your hierarchy:
public class PersonWithApprove : Person { // TODO: replace with non disgusting name
public bool Approved { get; set; }
// etc...
}
public class Student : PersonWithApprove {
}
public class Faculty : PersonWithApprove {
}
Or you could create an interface:
public interface IApprove {
bool Approved { get; set; }
// etc
}
public class Student : Person, IApprove {
}
You might also leave the class Approve as such, and have classes with a property of that type:
public class Student : Person {
Approve _approve = new Approve();
public Approve Approve {
get { return _approve; }
}
}
