下面的代码示例扩展 CreateParams 派生类的属性 Button 。 属性 CreateParams.Style 已更改，这会导致按钮显示 Icon 而不是 Image显示 。 此示例要求你有一个从类继承的 Button 类。

virtual System::Windows::Forms::CreateParams^ get() override
{
   
   // Extend the CreateParams property of the Button class.
   System::Windows::Forms::CreateParams^ cp = __super::CreateParams;

   // Update the button Style.
   cp->Style |= 0x00000040; // BS_ICON value
   return cp;
}

protected override CreateParams CreateParams
{
    get
    {
        // Extend the CreateParams property of the Button class.
        CreateParams cp = base.CreateParams;
        // Update the button Style.
        cp.Style |= 0x00000040; // BS_ICON value

        return cp;
    }
}
