Type.IsMarshalByRefImpl Method
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Implements the IsMarshalByRef property and determines whether the Type is marshaled by reference.
protected:
virtual bool IsMarshalByRefImpl();
protected virtual bool IsMarshalByRefImpl ();
abstract member IsMarshalByRefImpl : unit -> bool
override this.IsMarshalByRefImpl : unit -> bool
Protected Overridable Function IsMarshalByRefImpl () As Boolean
Returns
true
if the Type is marshaled by reference; otherwise, false
.
Examples
The following example determines whether the given type is marshaled by reference and displays the result.
