Using XmlSerializer to create an element with attributes and a value but no sub-element

Question

I find the answer here: Xmlserializer - Control Element-Attribute Pairing (revised).

Here is how to do it: mark the value property with the [XmlText] attribute.

public class Quantity {
  // your attributes
  [XmlAttribute]
  public string foo;

  [XmlAttribute]
  public string bar;

  // and the element value (without a child element)
  [XmlText]
  public int qty;

}
