Serialize class to XML?

Question

I have the follow class and the list that holds it:

public class Transport
{
    public string TransportType { get; set; }
    public string Mode { get; set;         


        

Answer 1

You need a stream and a XmlSerializer object, here's an example:

FileStream fs = new FileStream(@"C:\MyPath", FileMode.OpenOrCreate);

xmlSerializer = new XmlSerializer(typeof(MyClass));

xmlSerializer.Serialize(fs, myClassInstance);

fs.Flush();
fs.Close();
fs.Dispose();

Don't forget to handle errors your own way. And I'm also assuming you want to serialize all your class' properties.

Answer 2

If both of your classes were tagged with the [Serializable] attribute, then saving things to a file should be as simple as:

var serializer = new XmlSerializer(typeof(Transport));

using(var writer = new StreamWriter("C:\\Path\\To\\File.xml"))
{
    serializer.Serialize(writer, instance);
}

Update

Sorry, didn't realize you were asking about how to customize the output. That is what the [XmlAttribute] and [XmlElement] attributes are for:

public class Transport
{
    // Store TransportType as an attrribute called Type in the XML
    [XmlAttribute("Type")]
    public string TransportType { get; set; }

    // Rest of Implementation
}
