A HostedEventProviderCollection object.
Notas
Hosted event providers are event collection components that are hosted by the Notification Services engine and submit events to the application. An application can have zero or more hosted event providers. An application can also use non-hosted event providers.
Use the methods of the HostedEventProviderCollection class to add or remove HostedEventProvider objects.
Ejemplo
The following examples show how to define a hosted event provider and add it to an application using this HostedEventProviders property:
// Define a hosted event provider
HostedEventProvider flightEventProvider =
new HostedEventProvider(myApplication, "FlightEP");
flightEventProvider.ClassName = "FileSystemWatcherProvider";
flightEventProvider.SystemName = notificationServicesHost;
// Define event provider arguments
HostedEventProviderArgument fileArg_Directory =
new HostedEventProviderArgument(
flightEventProvider, "WatchDirectory");
fileArg_Directory.Value = sampleDirectory + @"\Events";
flightEventProvider.HostedEventProviderArguments.Add(
fileArg_Directory);
HostedEventProviderArgument fileArg_Schema =
new HostedEventProviderArgument(
flightEventProvider, "SchemaFile");
fileArg_Schema.Value = sampleDirectory +
@"\AppDefinition\EventsSchema.xsd";
flightEventProvider.HostedEventProviderArguments.Add(
fileArg_Schema);
HostedEventProviderArgument fileArg_EventClass =
new HostedEventProviderArgument(flightEventProvider,
"EventClassName");
fileArg_EventClass.Value = "FlightEvents";
flightEventProvider.HostedEventProviderArguments.Add(
fileArg_EventClass);
myApplication.HostedEventProviders.Add(flightEventProvider);
' Define a hosted event provider
Dim flightEventProvider As HostedEventProvider = _
New HostedEventProvider(myApplication, "FlightEP")
flightEventProvider.ClassName = "FileSystemWatcherProvider"
flightEventProvider.SystemName = notificationServicesHost
' Define event provider arguments
Dim fileArg_Directory As HostedEventProviderArgument = _
New HostedEventProviderArgument(flightEventProvider, _
"WatchDirectory")
fileArg_Directory.Value = sampleDirectory + "\Events"
flightEventProvider.HostedEventProviderArguments.Add( _
fileArg_Directory)
Dim fileArg_Schema As HostedEventProviderArgument = _
New HostedEventProviderArgument(flightEventProvider, _
"SchemaFile")
fileArg_Schema.Value = sampleDirectory + _
"\AppDefinition\EventsSchema.xsd"
flightEventProvider.HostedEventProviderArguments.Add( _
fileArg_Schema)
Dim fileArg_EventClass As HostedEventProviderArgument = _
New HostedEventProviderArgument(flightEventProvider, _
"EventClassName")
fileArg_EventClass.Value = "FlightEvents"
flightEventProvider.HostedEventProviderArguments.Add( _
fileArg_EventClass)
myApplication.HostedEventProviders.Add(flightEventProvider)
