Question

I can not figure out why I get this error.
As the code is quite a lot and I don’t get what might be wrong I post a link to all the files.
If someone might figure out why I get this error ” ‘Customer’ does not contain a constructor that takes 5 arguments ” … an hour I am stuck on this… this are the files
The error is in page book.aspx

if (Page.IsPostBack) 
{ 
   Customer c1 = new Customer(txtFirstname.Text, txtLastname.Text, txtAddress.Text, txtZip.Text, txtCity.Text); 
   Pet p1 = new Pet(txtSpecies.Text, txtName.Text,c1); 
   service.pets.Add(p1); 
}

Customer->

public Customer(int customerId, string firstname, string lastname, string address, string zipcode, string city, string email, string phone) 
     : base(firstname, lastname) 
{ 
    this.firstname = firstname; 
    this.lastname = lastname; 
} 

Answer 1

Constructor for Customer class is –

public Customer(int customerId, string firstname, string lastname,
                string address, string zipcode, string city, string email,
                string phone)

And from Book.aspx.cs you are creating instance like –

Customer c1 = new Customer(txtFirstname.Text, txtLastname.Text,
            txtAddress.Text, txtZip.Text, txtCity.Text);

Replace it with –

Customer c1 = new Customer(txtFirstname.Text, txtLastname.Text,
            txtAddress.Text, txtZip.Text, txtCity.Text, string.Empty,
              string.Empty, string.Empty);
