Is it possible to exclude some members of a type from XmlSerializer serialization?

Question

I have some public members I don't want to be serialized, was wondering if there is an attribute for it?

Answer 1

XmlIgnore will do the trick.

Answer 2

You are looking for XmlIgnore

Answer 3

Use XmlIgnore attribute

Answer 4

Use XmlIgnoreAttribute to do it statically, as others advised you.

You can also do it dynamically. Suppose you have a serializable property Name. Then the following:

[XmlIgnore]
public bool NameSpecified {
    get {
        // your logic here
    }
}

If this special property getter returns true, Name will be included in the output XML document, otherwise, it won't be included. NameSpecified itself is marked with [XmlIgnore] because you obviously don't want to include it.

Answer 5

Following on from Azheglov's comment regarding the "Specified" suffix, the DefaultValue attribute is also considered when serializing, and a value won't be serialized at all if it is the default.
