c# - 带有子类参数的函数

Question

所以我得到了一个 Person 类，它包含年龄、性别、姓名(和一个主键 ID)。然后我得到了 2 个 person 子类:

Teacher(Class(French, math, english etc etc), Sick(boolean))

student(Class(French, math, english etc etc), Sick(boolean)) 
//so these 2 got the same 5 fields.

现在我想制作一种可以创建所有 2 个方法的方法。 (在实践中还有更多，但对于这个问题，我将只使用这两个)

这就是我的想法:

public Person CreateNewPerson (int age, boolean sex, string name, int class, boolean sick, HELP HERE plz OFTYPE<TEACHER OR STUDENT>)
{
    var Person1 = new Person { Age = age, Sex = sex, ....... };
    // but now to return it as the correct type I got no clue what todo
    return (OFTYPE)Person1; // ofc this doesn t work but I hope you understand the problem here
}

希望有人能在这里帮助我，因为 atm 我正在为我得到的每个子类制作一个单独的 CreateNewTeacher、CreateNewStudent 等等。(我喜欢其中 5 个 ^^)

提前致谢!

PS:它们稍后保存在不同的表中，我不希望它们都在同一个类中，因为我知道我可以去添加一个 bool 值 person: IsPersonChild 然后 true 或flase but na h

Answer 1

建议的类(class)设置:

public class Person
{
    public string Name { get; set; }
}

public class Teacher : Person
{
}

public class Student : Person
{
}

public static class PersonFactory
{
    public static T MakePerson<T>(string name) where T: Person, new()
    {
        T person = new T {Name = name};
        return person;
    }
}

用法:

Teacher teacher = PersonFactory.MakePerson<Teacher>("Mrs. Smith");

Student student = PersonFactory.MakePerson<Student>("Johnny");
