Type.IsMarshalByRefImpl Method

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

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
Protected Overridable Function IsMarshalByRefImpl As Boolean

Return Value

Type: System.Boolean
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.

Imports System
Imports System.Reflection
Imports Microsoft.VisualBasic

Public Class MyTypeDelegatorClass
    Inherits TypeDelegator
    Public myElementType As String = Nothing 
    Private myType As Type = Nothing 
    Public Sub New(ByVal myType As Type)
        Me.myType = myType
    End Sub 'New 

    ' Override IsMarshalByRefImpl. 
    Protected Overrides Function IsMarshalByRefImpl() As Boolean 
        ' Determine whether the type is marshalled by reference. 
        If myType.IsMarshalByRef Then
            myElementType = " marshalled by reference" 
            Return True
