    <p>I have a main class called <code>theGarage</code>, which contains instances of our customer, supplier, and jobs classes.</p> <p>I want to save the program data to an XML file, I have used the code below (just a snippet, I have matching code for the other classes). I am wondering if there is an easier way for me to do this, like write the whole theGarage class to an XML file and read it in without having to write all this code like I have below. </p> <pre><code> public void saveToFile() { using (XmlWriter writer = XmlWriter.Create("theGarage.xml")) { writer.WriteStartDocument(); /// writer.WriteStartElement("theGarage"); writer.WriteStartElement("Customers"); foreach (Customer Customer in Program.theGarage.Customers) { writer.WriteStartElement("Customer"); writer.WriteElementString("FirstName", Customer.FirstName); writer.WriteElementString("LastName", Customer.LastName); writer.WriteElementString("Address1", Customer.Address1); writer.WriteElementString("Address2", Customer.Address2); writer.WriteElementString("Town", Customer.Town); writer.WriteElementString("County", Customer.County); writer.WriteElementString("PostCode", Customer.Postcode); writer.WriteElementString("TelephoneHome", Customer.TelephoneHome); writer.WriteElementString("TelephoneMob", Customer.TelephoneMob); //begin vehicle list writer.WriteStartElement("Vehicles"); foreach (Vehicle Vehicle in Customer.Cars) { writer.WriteStartElement("Vehicle"); writer.WriteElementString("Make", Vehicle.Make); writer.WriteElementString("Model", Vehicle.Model); writer.WriteElementString("Colour", Vehicle.Colour); writer.WriteElementString("EngineSize", Vehicle.EngineSize); writer.WriteElementString("Registration", Vehicle.Registration); writer.WriteElementString("Year", Vehicle.YearOfFirstReg); writer.WriteEndElement(); } writer.WriteEndElement(); writer.WriteEndElement(); } } } </code></pre>

    1. COwhat kind of application are you writing? Are you just trying to save a session across uses for a single-user, GUI application? Otherwise (if you're doing something that could be used by multiple concurrent users, for instance) you may want to consider not storing the info in files. Even in the single user scenario, there may be better alternatives (like SQLite) to store your data

    3. COwell, there are various "lighter" options depending on your scenario. If you can expand some more on what kind of application you're writing people here will be able to suggest something suitable.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
