Public ReadOnly Property CheckSpecified As Boolean
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.
