ignoreCase
Boolean

true if you want to ignore the case of the event; otherwise, false.

Returns

EventDescriptor

The EventDescriptor with the specified name, or null if the event does not exist.

Examples

The following code example finds a specific EventDescriptor. It prints the type of component for this EventDescriptor in a text box. It requires that button1 and textBox1 have been instantiated on a form.

private:
   void FindEvent()
   {
      // Creates a new collection and assigns it the events for button1.
      EventDescriptorCollection^ events = TypeDescriptor::GetEvents( button1 );
      
      // Sets an EventDescriptor to the specific event.
      EventDescriptor^ myEvent = events->Find( "Resize", false );
      
      // Prints the event name and event description.
      textBox1->Text = String::Concat( myEvent->Name, ": ", myEvent->Description );
   }

private void FindEvent() {
    // Creates a new collection and assigns it the events for button1.
    EventDescriptorCollection events = TypeDescriptor.GetEvents(button1);
 
    // Sets an EventDescriptor to the specific event.
    EventDescriptor myEvent = events.Find("Resize", false);
 
    // Prints the event name and event description.
    textBox1.Text = myEvent.Name + ": " + myEvent.Description;
 }

Private Sub FindEvent()
    ' Creates a new collection and assigns it the events for button1.
    Dim events As EventDescriptorCollection = TypeDescriptor.GetEvents(button1)
    
    ' Sets an EventDescriptor to the specific event.
    Dim myEvent As EventDescriptor = events.Find("Resize", False)
    
    ' Prints the event name and event description.
    textBox1.Text = myEvent.Name & ": " & myEvent.Description
End Sub
