Returns

IEnumerator

An enumerator that implements IEnumerator.

Implements

GetEnumerator()

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
