Fluent interfaces and inheritance in C#

by

Try to use some Extension methods.

static class FluentManager
{
    public static T WithFirstName<T>(this T person, string firstName) where T : FluentPerson
    {
        person.FirstName = firstName;
        return person;
    }

    public static T WithId<T>(this T customer, long id) where T : FluentCustomer
    {
        customer.ID = id;
        return customer;
    }
}

class FluentPerson
{
    public string FirstName { private get; set; }
    public string LastName { private get; set; }

    public override string ToString()
    {
        return string.Format("First name: {0} last name: {1}", FirstName, LastName);
    }
}

class FluentCustomer : FluentPerson
{
    public long ID { private get; set; }
    public long AccountNumber { private get; set; }

    public override string ToString()
    {
        return base.ToString() + string.Format(" account number: {0} id: {1}", AccountNumber, ID);
    }
}

after you can use like

new FluentCustomer().WithId(22).WithFirstName("dfd").WithId(32);
