Type.IsMarshalByRefImpl Methode

protected:
 virtual bool IsMarshalByRefImpl();

protected virtual bool IsMarshalByRefImpl ();

abstract member IsMarshalByRefImpl : unit -> bool
override this.IsMarshalByRefImpl : unit -> bool

Protected Overridable Function IsMarshalByRefImpl () As Boolean

Gibt zurück

true, wenn Type als Verweis gemarshallt wird, andernfalls false.
