Examples
The following code example gets an enumerator for the events on button1
. It uses the enumerator to print the names of the events in the collection. It requires that button1
and textBox1
have been instantiated on a form.
private:
void MyEnumerator()
{
// Creates a new collection, and assigns to it the events for button1.
EventDescriptorCollection^ events = TypeDescriptor::GetEvents( button1 );
// Creates an enumerator.
IEnumerator^ ie = events->GetEnumerator();
// Prints the name of each event in the collection.
Object^ myEvent;
while ( ie->MoveNext() == true )
{
myEvent = ie->Current;
textBox1->Text = String::Concat( textBox1->Text, myEvent, "\n" );
}
}
private void MyEnumerator() {
// Creates a new collection, and assigns to it the events for button1.
EventDescriptorCollection events = TypeDescriptor.GetEvents(button1);
// Creates an enumerator.
IEnumerator ie = events.GetEnumerator();
// Prints the name of each event in the collection.
Object myEvent;
while(ie.MoveNext() == true) {
myEvent = ie.Current;
textBox1.Text += myEvent.ToString() + '\n';
}
}
Private Sub MyEnumerator()
' Creates a new collection, and assigns to it the events for button1.
Dim events As EventDescriptorCollection = TypeDescriptor.GetEvents(button1)
' Creates an enumerator.
Dim ie As IEnumerator = events.GetEnumerator()
' Prints the name of each event in the collection.
Dim myEvent As Object
While ie.MoveNext() = True
myEvent = ie.Current
textBox1.Text += myEvent.ToString() & ControlChars.Cr
End While
End Sub
