예

The following example shows how to set the value of an event data field using the name of the field:

string instanceName = "Tutorial";
string applicationName = "Weather";
string eventClassName = "WeatherEvents";
string eventProviderName = "WeatherSPs";

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

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

// Create an EventCollector object.
EventCollector testEventCollector =
    new EventCollector(testApplication, eventProviderName);

// Create and define an Event object.
Event evt = new Event(testApplication, eventClassName);
evt["City"] = "Seattle";
evt["Date"] = DateTime.Now;
evt["Low"] = 40;
evt["High"] = 50;
evt["Forecast"] = "Cloudy";

// Write the event to the event collector's batch
testEventCollector.Write(evt);

// Commit the event batch to the application database.
testEventCollector.Commit();
