範例

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

Dim instanceName As String =  "Tutorial" 
Dim applicationName As String =  "Weather" 
Dim subscriptionClassName As String =  "WeatherCity" 
Dim fieldName As String =  "City" 
Dim ordinal As Integer =  2 
 
' Create the NSInstance object.
Dim testInstance As New NSInstance(instanceName)
 
' Create the NSApplication object.
Dim testApplication As New NSApplication( _
    testInstance, applicationName)
 
' Create the Subscription object.
Dim testSubscription As New Subscription( _
    testApplication, subscriptionClassName)
 
' Use the GetFieldName method to return a field name
Console.WriteLine("Name of field " + ordinal.ToString() + _
    ": " + testSubscription.GetFieldName(ordinal))
 
' Use the GetFieldOrdinal to return a field ordinal
Console.WriteLine("Ordinal for the " + fieldName + _
    " field: " + testSubscription.GetFieldOrdinal(fieldName))

string instanceName = "Tutorial";
string applicationName= "Weather";
string subscriptionClassName= "WeatherCity";
string fieldName = "City";
int ordinal = 2;

// Create the NSInstance object.
NSInstance testInstance = new NSInstance(instanceName);

// Create the NSApplication object.
NSApplication testApplication =
    new NSApplication(testInstance, applicationName);

// Create the Subscription object.
Subscription testSubscription =
    new Subscription(testApplication, subscriptionClassName);

// Use the GetFieldName method to return a field name
Console.WriteLine("Name of field " + ordinal.ToString() + ": " + 
    testSubscription.GetFieldName(ordinal));

// Use the GetFieldOrdinal to return a field ordinal
Console.WriteLine("Ordinal for the " + fieldName + " field: " +
    testSubscription.GetFieldOrdinal(fieldName));
