LiFeDataSource.RelativePath
LiFeDataSource.RelativePath property
Ruft den relativen Pfad der externen Datei in der LiFE-Datenquelle der PSD-LnkE-Ressource ab oder legt ihn fest.
public string RelativePath { get; set; }
Eigentumswert
Der relative Dateipfad.
Ausnahmen
| Ausnahme | Bedingung |
|---|---|
| PsdImageException | Sie können nicht auf die RelativePath-Eigenschaft zugreifen, sie ist nur für die LIFE-Datenquelle verfügbar |
