How can I get XmlSerializer to encode bools as yes/no?

Question

I\'m sending xml to another program, which expects boolean flags as \"yes\" or \"no\", rather than \"true\" or \"false\".

I have a class defined like:

Very simple. Use a surrogate property. Apply XmlIgnore on the actual property. The surrogate is a string, and must use the XmlElement attribute that takes a element-name override. Specify the name of the actual property in the override. The surrogate property serializes differently based on the value of the actual property. You must also provide a setter for the Surrogate, and the setter should set the actual property appropriately, for whatever value it serialized. In other words it needs to go both ways.

Snip:

    public class SomeType 
    {

        [XmlElement]
        public int IntValue;

        [XmlIgnore]
        public bool Value;

        [XmlElement("Value")]
        public string Value_Surrogate {
            get { return (Value)? "Yes, definitely!":"Absolutely NOT!"; }
            set { Value= (value=="Yes, definitely!"); }
        }

    }
