Parent Elements

Element	Description
UnderlyingType	Represents the underlying integral type of a proxy enumeration for a COM or managed enumeration.

Example

The following example demonstrates an ExternalTypeReference element that describes the underlying integral type of a proxy enumeration named ShapeType. The underlying type is Int32.

<Enum originalFullyQualifiedName="ShapeApp.Proxy.ShapeType" 
    isExcluded="false"
    newNamespace="ShapeApp.Proxy">
  <UnderlyingType>
    <ExternalTypeReference isInterface="false" type="System.Int32" />
  </UnderlyingType>
  <EnumerationValue originalName="Circle" value="0" />
  <EnumerationValue originalName="Square" value="1" />
  <EnumerationValue originalName="Triangle" value="2" />
  <EnumerationValue originalName="Octagon" value="3" />
  <EnumerationValue originalName="Star" value="4" />
</Enum>
