Type.IsMarshalByRefImpl Method

Implements the IsMarshalByRef property and determines whether the Type is marshaled by reference.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

'Declaration
Protected Overridable Function IsMarshalByRefImpl As Boolean
'Usage
Dim returnValue As Boolean

returnValue = Me.IsMarshalByRefImpl
protected boolean IsMarshalByRefImpl ()
protected function IsMarshalByRefImpl () : boolean

Return Value

true if the Type is marshaled by reference; otherwise, false.

This method can be overridden by a derived class.

The following example determines whether the given type is marshaled by reference and displays the result.
