示例

The following examples show how to use the Update method to modify subscription information:

' Create the NSInstance object.
Dim testInstance As New NSInstance("Tutorial")
 
' Create the NSApplication object.
Dim testApplication As _
    New NSApplication(testInstance, "Weather")
 
' Create the Subscription object.
Dim testSubscription As _
    New Subscription(testApplication, "WeatherCity")
 
 
'Create a SubscriptionEnumeration object.
' that contains all of the subscriber's subscriptions
' in a specific subscription class
Dim testSubscriptionEnumeration As _
    New SubscriptionEnumeration(testApplication, "WeatherCity", "TestUser1")
 
'Iterate through the subscriptions, finding the subscription
' to match. In a user interface, you would probably list the 
' subscriptions in a list box and then let the user
' alter the data for the selected subscription
Dim subscription As Subscription
For Each subscription In testSubscriptionEnumeration
    Dim city As String =  subscription.GetFieldValue("City").ToString() 
    Console.WriteLine(city)
    Console.WriteLine("Subscription ID: {0}", subscription.SubscriptionId)
    If city.Equals("Shoreline") Then
         testSubscription.SubscriptionId = subscription.SubscriptionId
    End If
Next
 
' Set all of the subscription data fields 
testSubscription("DeviceName") = "Work e-mail"
testSubscription("SubscriberLocale") = "en-US"
testSubscription("City") = "Edmonds"
 
testSubscription.Update()

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

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

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


//Create a SubscriptionEnumeration object.
// that contains all of the subscriber's subscriptions
// in a specific subscription class
SubscriptionEnumeration testSubscriptionEnumeration = 
    new SubscriptionEnumeration(testApplication, 
        "WeatherCity", "TestUser1");

//Iterate through the subscriptions, finding the subscription
// to match. In a user interface, you would probably list the 
// subscriptions in a list box and then let the user
// alter the data for the selected subscription
foreach (Subscription subscription in testSubscriptionEnumeration)
{
    String city = subscription.GetFieldValue("City").ToString();
    Console.WriteLine(city);
    Console.WriteLine("Subscription ID: {0}", subscription.SubscriptionId);
        if (city.Equals("Shoreline"))
            testSubscription.SubscriptionId = subscription.SubscriptionId;
}

// Set all of the subscription data fields 
testSubscription["DeviceName"] = "Work e-mail";
testSubscription["SubscriberLocale"] = "en-US";
testSubscription["City"] = "Edmonds";

testSubscription.Update();
