This API supports the product infrastructure and is not intended to be used directly from your code.

Gets a value that indicates whether the accompanying field in the .NET Framework type has a value specified.

Namespace:   System.Xml.Serialization
Assembly:  System.Xml (in System.Xml.dll)

public bool CheckSpecified { get; }

Property Value

Type: System.Boolean

true, if the accompanying field has a value specified; otherwise, false.

In the XML Schema, an element declared with a minOccurs="0" attribute value indicates that the element is optional. An attribute can be declared with a use="optional" attribute. The .NET Framework, using the XML Schema Definition Tool (Xsd.exe), maps either of these constructs to a public field or property that is accompanied by a public field of type bool whose name is the first field's name with "Specified" appended. The CheckSpecified property checks whether such a bool field exists.
