POHow to work with an object that was instantiated inside another object from a ASP.NET web form
text
Body
copied!<p>This is probably a very simple question but I'm a little confused when it comes to working with an object created from a class that contains a field where the type is another class. The part that confuses me is how to populate the field with data from the web form. </p> <p>For example, if I have a <code>customer</code> class that has a field called <code>contact</code> which is of type <code>Contact</code>, what is the proper way to populate this at the web form level? At present I am doing it as follows and would like to know if this is correct.</p> <p>This is the code from my <code>customer</code> class and <code>contact</code> is another class.</p> <pre><code>public class Customer { private string firstName; private string lastName' private string notes; private Contact contact; public Customer() { this.contact = new Contact(); } public string FirstName { get { return firstName; } set { firstName = value; } } public string LastName { get { return lastName; } set { lastName = value; } } public string Notes { get { return notes; } set { notes = value; } } public Contact Contact { get { return contact; } set { contact = value; } } } </code></pre> <p>Code from my form</p> <pre><code>private Customer customer; public WebFormSample() { customer = new AddressBook.Customer(); } protected void addButton_Click(object sender, EventArgs e) { customer.FirstName = firstName.Text; customer.LastName = lastName.Text; customer.Contact.Phone = phone.Text; customer.Contact.Email = Email.Text; } </code></pre> <p>Is this the way I should be working with the <code>contact</code> object or should I have instantiated a <code>contact</code> object on the web form, populate it and then assign it to contact in the <code>customer</code> object or have I got it completely wrong and this should be done in a completely different way? </p> <p>Hope this makes sense.</p> <p>Thanks </p>
