I need to add a custom property to the Rectangle class. I tried to subclass the Rectangle class but it didn't work. Is there a way to do that. Thanks

推荐答案

你不能从 System.Drawing.Rectangle 继承，因为它不是一个类，它是一个 struct代码>.您可以做的是创建自己的类(或 struct)来包装 Rectangle，例如:

You can't inherit from System.Drawing.Rectangle, because it's not a class, it's a struct. What you can do is to create your own class (or struct) that wraps Rectangle, something like:

class MyRectangle
{
    public Rectangle ActualRectangle { get; set; }
    public SomeType AdditionalProperty { get; set; }
}

或者您可以隐藏 Rectangle 并提供与调用它们的 Rectangle 的方法和属性相同的方法和属性.

Or you could hide the Rectangle and provide methods and properties that mirror those of Rectangle that call them.
