주의
The Script component developer makes variables available to the Script component for read-only access by listing them in the ReadOnlyVariables field in the Script Transformation Component Editor.
The Script component developer does not use the ScriptComponent class directly, but indirectly, by coding the methods and properties of the ScriptMain class, which inherits from ScriptComponent through the UserComponent class.
The developer does not have to use the ReadOnlyVariables property, because the ScriptMain class provides the Variables property for convenient access to both read-only and read/write variables through a single property. The Variables property is a property of the autogenerated UserComponent base class, not of the ScriptComponent class.
예
The following code sample demonstrates how the Script component developer might use the ReadOnlyVariables and ReadWriteVariables properties.
Dim localInteger As Integer
Dim localString As String
If Me.ReadOnlyVariables.Contains("MyIntegerVariable") Then
localInteger = CType(Me.ReadOnlyVariables("MyIntegerVariable").Value, Integer)
End If
If Me.ReadWriteVariables.Contains("MyStringVariable") Then
Me.ReadWriteVariables("MyStringVariable").Value = localString
End If
