Példák

Az alábbi példakód egy enumerátort kér le a következő button1attribútumokhoz: . Az enumerátor használatával nyomtatja ki a gyűjtemény attribútumainak nevét. Ezt feltételezi, button1 és textBox1 egy űrlapon lett létrehozva.

private:
   void MyEnumerator()
   {
      // Creates a new collection and assigns it the attributes for button1.
      AttributeCollection^ attributes;
      attributes = TypeDescriptor::GetAttributes( button1 );
      
      // Creates an enumerator for the collection.
      System::Collections::IEnumerator^ ie = attributes->GetEnumerator();
      
      // Prints the type of each attribute in the collection.
      Object^ myAttribute;
      System::Text::StringBuilder^ text = gcnew System::Text::StringBuilder;
      while ( ie->MoveNext() )
      {
         myAttribute = ie->Current;
         text->Append( myAttribute );
         text->Append( '\n' );
      }
      textBox1->Text = text->ToString();
   }

void MyEnumerator()
{
    // Creates a new collection and assigns it the attributes for button1.
    AttributeCollection attributes;
    attributes = TypeDescriptor.GetAttributes(button1);

    // Creates an enumerator for the collection.
    System.Collections.IEnumerator ie = attributes.GetEnumerator();

    // Prints the type of each attribute in the collection.
    object myAttribute;
    while (ie.MoveNext())
    {
        myAttribute = ie.Current;
        textBox1.Text += myAttribute.ToString();
        textBox1.Text += '\n';
    }
}

Private Sub MyEnumerator
    ' Creates a new collection and assigns it the attributes for button1.
    Dim attributes As AttributeCollection
    attributes = TypeDescriptor.GetAttributes(button1)

    ' Creates an enumerator for the collection.
    Dim ie As System.Collections.IEnumerator = attributes.GetEnumerator

    ' Prints the type of each attribute in the collection.
    Dim myAttribute As Object
    Do While ie.MoveNext
        myAttribute = ie.Current
        textBox1.Text = textBox1.Text & myAttribute.toString & ControlChars.crlf
    Loop
End Sub
