Gets or sets a value that indicates whether the XmlSerializer must serialize a member that has the xsi:null attribute set to "1".
public:
property bool IsNullable { bool get(); void set(bool value); };public bool IsNullable { get; set; }member this.IsNullable : bool with get, setPublic Property IsNullable As BooleanProperty Value
true if the XmlSerializer generates the xsi:null attribute; otherwise, false.
Remarks
The XML schema specification for structures allows an XML document to explicitly signal that an element's content is missing. Such an element contains the attribute xsi:null set to "1". For more information, see the World Wide Web Consortium specification named XML Schema Part 1: Structures.
If the IsNullable property is set to true, the xsi:null attribute is generated for class members that have been set to null. For example, if you set a field named MyStringArray to null, the XmlSerializer generates the following XML code.
<MyStringArray xsi:null = "1" />
If the IsNullable property is false, no XML element is generated.
Note
You cannot apply the IsNullable property to a member typed as a value type because a value type cannot contain null.
