Der NET Framework-Typ der datengebundenen Eigenschaft.

Beispiel

Im folgenden Codebeispiel werden die drei Variablen dataBindingOutput1, dataBindingOutput2 und dataBindingOutput3 definiert, die auf die verschiedenen Eigenschaften eines DataBinding-Objekts mit dem Namen myDataBinding2 zugreifen. Der PropertyType-Eigenschaftenwert wird zu dataBindingOutput2 zugewiesen und mit der Zeichenfolge "The property type is " verkettet, und der Wert wird in eine Datei geschrieben.
