Represents an Automation event.
Assembly: System.Windows (in System.Windows.dll)
The AutomationEvent type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | AddEventHandler | Attaches the specified delegate to the Automation event. |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | RemoveEventHandler | Detaches the specified delegate from the Automation event. |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The following code example demonstrates how to handle Automation events.
private void SearchEmail() { UpdateStatusMessage("Searching Inbox for 'WindowsPhone'..."); // The following code demonstrates three ways to handle Automation // events. The first two ways use the AutomationEvent class. // The last two ways require the use of a delegate with // an API signature that matches the Automation event. AutomationEvent searchEvent = AutomationFactory .GetEvent(outlook, "AdvancedSearchComplete"); // The first way: searchEvent.EventRaised += (sender, e) => { SearchComplete(e.Arguments[0]); }; // The second way: // searchEvent.AddEventHandler( // new AdvancedSearchCompleteDelegate(SearchComplete)); // The third way: // outlook.AdvancedSearchComplete += // new AdvancedSearchCompleteDelegate(SearchComplete); // Begin the search. outlook.AdvancedSearch("Inbox", "urn:schemas:mailheader:subject ci_phrasematch 'WindowsPhone'", true, "SubjectSearch"); } // Required only with the second two ways of handling Automation events. private delegate void AdvancedSearchCompleteDelegate(dynamic search); // To use custom delegates for events with optional parameters, you // must specify default values in the delegate signature as shown here: // private delegate void MyEventHandlerDelegate(int i, float f=77); private void SearchComplete(dynamic search) { List<String> searchResults = new List<String>(); foreach (dynamic result in search.Results) { searchResults.Add(result.Subject); } SetResultsList(searchResults); }
