XmlArrayAttribute.IsNullable Property
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Gets or sets a value that indicates whether the XmlSerializer must serialize a member as an empty XML element with the xsi:nil attribute set to true.
Assembly: System.Xml (in System.Xml.dll)
Property Value
Type: System.Booleantrue if the XmlSerializer generates the xsi:nil attribute; otherwise, false.
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:nil set to true. For more information, see the World Wide Web Consortium (www.w3.org) specification, XML Schema Part 1: Structures.
If the IsNullable property is set to true, the xsi:nil attribute is generated for class members that have been set to Nothing. For example, if you set a field named MyStringArray to Nothing, the XmlSerializer generates the following XML code.
<MyStringArray xsi:nil = "true" />
If the IsNullable property is false, no XML element is generated.

You cannot apply the IsNullable property to a member typed as a value type because a value type cannot contain Nothing. |
