Belangrijk

Bepaalde informatie heeft betrekking op een voorlopige productversie die aanzienlijk kan worden gewijzigd voordat deze wordt uitgebracht. Microsoft biedt geen enkele expliciete of impliciete garanties met betrekking tot de informatie die hier wordt verstrekt.

Hiermee wordt een waarde opgehaald die aangeeft of het retourtype voor de methode die wordt vertegenwoordigd door het exemplaar van LogicalMethodInfo is void.

public:
 property bool IsVoid { bool get(); };

public bool IsVoid { get; }

member this.IsVoid : bool

Public ReadOnly Property IsVoid As Boolean

Waarde van eigenschap

Boolean

true als het retourtype ongeldig is; anders, false.
