c# Fields to include in parameterized constructor, of a class that has derived from another class that has derived from abstract class

I have a class Accommodation as follows: 

class Accommodation {
    int accommodationNo
    String address1
    String address2
    String postcode
    double valuation
    double rent
    int noRentPaymentsPerYe
}

Class Housing extends Accommodation:

class Housing : Accomodation {
    String type
    int noBedrooms
    int noCarParkingSites
}

And class Flat extends Housing:

class Flat : Housing {
    double maintenanceCharge
}

When creating a constructor with parameters of Flat class, do I include every field up to Accommodation? An example of a constructor with parameters of class Flat would be highly appreciated.

Yes, you have to include every field, and pass that down the chain of constructors (this is an abbreviation of the fields since only a couple per class is needed to demonstrate - you would need to add your additional fields):

public abstract class Accommodation {
    private int accommodationNo;
    private String address1;
    protected Accomodation(int acomNo, string addr1) {
        this.accomodationNo = acomNo;
        this.address1 = addr1;
    }
}
public class Housing {
    private String type;
    private int noBedrooms;
    public Housing(int acomNo, string addr1, string typ, int noBeds) 
            : base(acomNo, addr1) {
        this.type = typ;
        this.noBedrooms = noBeds;
    }
}
public class Flat {
    double maintenanceCharge;
    public Flat(int acomNo, string addr1, string typ, int noBeds, double maintCharge) 
            : base(acomNo, addr1, typ, noBeds) {
        this.maintenanceCharge = maintCharge;
    }
}
