private:
   void FindProperty()
   {
      // Creates a new collection and assign it the properties for button1.
      PropertyDescriptorCollection^ properties = TypeDescriptor::GetProperties( button1 );
      
      // Sets a PropertyDescriptor to the specific property.
      PropertyDescriptor^ myProperty = properties->Find( "Opacity", false );
      
      // Prints the property and the property description.
      textBox1->Text = myProperty->DisplayName + "\n" + myProperty->Description;
   }

private void FindProperty() {
   // Creates a new collection and assign it the properties for button1.
   PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(button1);

   // Sets a PropertyDescriptor to the specific property.
   PropertyDescriptor myProperty = properties.Find("Opacity", false);

   // Prints the property and the property description.
   textBox1.Text = myProperty.DisplayName + '\n' + myProperty.Description;
}

Private Sub FindProperty()
    ' Creates a new collection and assign it the properties for button1.
    Dim properties As PropertyDescriptorCollection = _
       TypeDescriptor.GetProperties(button1)
       
    ' Sets a PropertyDescriptor to the specific property.
    Dim myProperty As PropertyDescriptor = properties.Find("Opacity", False)
       
    ' Prints the property and the property description.
    textBox1.Text = myProperty.DisplayName & _
       Microsoft.VisualBasic.ControlChars.Cr & myProperty.Description
End Sub
