Determines whether the specified object is an instance of the Type.
[Visual Basic] Overridable Public Function IsInstanceOfType( _ ByVal o As Object _ ) As Boolean [C#] public virtual bool IsInstanceOfType( object o ); [C++] public: virtual bool IsInstanceOfType( Object* o ); [JScript] public function IsInstanceOfType( o : Object ) : Boolean;
true if o is an instance of the Type; otherwise, false.
This method can be overridden by a derived class.
a null reference (in Visual Basic Nothing) is considered an instance of any type, therefore this method will always return true if o is a null reference (Nothing).
