Syntaxe

Visual Basic (Déclaration)
Public Sub AppendSwitch ( _
    switchName As String _
)
Visual Basic (Utilisation)
Dim instance As CommandLineBuilder
Dim switchName As String

instance.AppendSwitch(switchName)
C#
public void AppendSwitch(
    string switchName
)
VisualC++
public:
void AppendSwitch(
    String^ switchName
)
J#
public void AppendSwitch(
    String switchName
)
JScript
public function AppendSwitch(
    switchName : String
)

Paramètres

switchName
