示例

The following examples show how to use the FieldTypeMods method to get the field modifiers of a subscription field by providing the field ordinal:

Dim instanceName As String = "MyInstanceName"
Dim applicationName As String = "MyApplicationName"
Dim subscriptionClassName As String = "MySubscriptionClassName"
Dim fieldOrdinal As Integer = 0

'Create an NSInstance object.
Dim myInstance As New NSInstance(instanceName)

'Create an NSApplication object.
Dim myApplication As New NSApplication(myInstance, applicationName)

'Create a SubscriptionClassEnumeration object.
Dim mySubscriptionClassEnumeration As _
    New SubscriptionClassEnumeration(myApplication)

'Use the SubscriptionClassEnumeration.Item 
'to return a SubscriptionClass object.
Dim mySubscriptionClass As SubscriptionClass = _
    mySubscriptionClassEnumeration(subscriptionClassName)

'Use the FieldTypeMods method to get a field's modifiers.
Dim fieldTypeMods As String = _
    mySubscriptionClass.FieldTypeMods(fieldOrdinal)

string instanceName = "MyInstanceName";
string applicationName = "MyApplicationName";
string subscriptionClassName = "MySubscriptionClassName";
int fieldOrdinal = 0;

//Create an NSInstance object.
NSInstance myInstance = new NSInstance(instanceName);

//Create an NSApplication object.
NSApplication myApplication = 
    new NSApplication(myInstance, applicationName);

//Create a SubscriptionClassEnumeration object.
SubscriptionClassEnumeration mySubscriptionClassEnumeration = 
    new SubscriptionClassEnumeration(myApplication);

//Use the SubscriptionClassEnumeration.Item 
//to return a SubscriptionClass object.
SubscriptionClass mySubscriptionClass = 
    mySubscriptionClassEnumeration[subscriptionClassName];

//Use the FieldTypeMods method to get a field's modifiers.
string fieldTypeMods  = 
    mySubscriptionClass.FieldTypeMods(fieldOrdinal);
