If you use the default constructor, you must immediately set the Name property and then set the Parent property. You can then set other properties.

重要提示：
The default constructor does not set default property values. If you do not set values for required properties, Notification Services will throw an exception when you create or update the application. For a list of required properties and their default values, see the examples below or the Microsoft.SqlServer.Management.Nmo.Application constructor.

示例

The following examples show how to use the default constructor for the Application class. Because the default constructor does not set property defaults, you must provide values for the properties shown in these examples. The values shown below are primarily the same as the defaults set by the other constructor; the primary difference is that the Log* properties are set to false.

// Create application and set required properties.
Application myApplication = new Application();
myApplication.Name = applicationName;
myApplication.Parent = myInstance;
myApplication.SchemaName = "dbo";
myApplication.ChronicleQuantumLimit = 1440;
myApplication.SubscriptionQuantumLimit = 30;
myApplication.QuantumDuration = new TimeSpan(0, 1, 0);
myApplication.VacuumRetentionAge = new TimeSpan(7, 0, 0, 0);
myApplication.PerformanceQueryInterval = new TimeSpan(0, 1, 0);
myApplication.ProcessEventsInOrder = false;
myApplication.EventThrottle = 1000;
myApplication.SubscriptionThrottle = 1000;
myApplication.NotificationThrottle = 1000;
myApplication.LogBeforeDeliveryAttempts = false;
myApplication.LogStatusInfo = false;
myApplication.LogNotificationText = false;
myApplication.BaseDirectoryPath = @"C:\NS\Default";
myApplication.ApplicationDefinitionFilePath = @"C:\NS";

' Create application and set required properties.
Dim myApplication As Application = New Application()
myApplication.Name = applicationName
myApplication.Parent = myInstance
myApplication.SchemaName = "dbo"
myApplication.ChronicleQuantumLimit = 1440
myApplication.SubscriptionQuantumLimit = 30
myApplication.QuantumDuration = New TimeSpan(0, 1, 0)
myApplication.VacuumRetentionAge = New TimeSpan(7, 0, 0, 0)
myApplication.PerformanceQueryInterval = New TimeSpan(0, 1, 0)
myApplication.ProcessEventsInOrder = False
myApplication.EventThrottle = 1000
myApplication.SubscriptionThrottle = 1000
myApplication.NotificationThrottle = 1000
myApplication.LogBeforeDeliveryAttempts = False
myApplication.LogStatusInfo = False
myApplication.LogNotificationText = False
myApplication.BaseDirectoryPath = "C:\NS\Default"
myApplication.ApplicationDefinitionFilePath = "C:\NS"
