Hinweise

CodePropertySetValueReferenceExpression stellt das Wertargument eines Methodenaufrufs für ein Eigenschaftenset in einer Methodendeklaration eines Eigenschaftensets dar.

Eine Methode für Eigenschaftensets weist i. d. R. der Eigenschaft einen Wert zu oder verwendet diesen zugewiesenen Wert. Innerhalb der Methode für Eigenschaftensets wird dieser Wert durch eine implizite Variable dargestellt, die in CodeDOM durch eine CodePropertySetValueReferenceExpression dargestellt wird.

Beispiel

In diesem Beispiel wird veranschaulicht, wie mit einer CodePropertySetValueReferenceExpression das Wertargument dargestellt wird, das an einen Anweisungsblock für Eigenschaftensetwerte übergeben wird.

' Declares a type.
Dim type1 As New CodeTypeDeclaration("Type1")
