示例

The following examples show how to define a hosted event provider:

// 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)
