什么是"适当的"方法来检索到功能区对象的引用？

问题描述：

对于VSTO工作簿的项目，有没有从ThisWorkbook类检索到功能区对象的引用的最佳做法？

For a VSTO workbook project, is there a best practice for retrieving a reference to the Ribbon object from the ThisWorkbook class?

下面是我在做什么：在我区类，我创建了一个名为 InvalidateControl（字符串控件ID）的公共方法。我需要根据当某个工作簿级事件触发调用该方法从ThisWorkbook类。但我可以看到的唯一途径获得到色带对象的引用是做到这一点...

Here's what I'm doing: In my Ribbon class, I created a public method called InvalidateControl(string controlID). I need to call that method from the ThisWorkbook class based on when a certain workbook level event fires. But the only way I can see to "get" a reference to that Ribbon object is to do this...

    // This is all in the ThisWorkbook class
    Ribbon ribbon;
    protected override IRibbonExtensibility CreateRibbonExtensibilityObject()
    {
        this.ribbon = new Ribbon();
        return this.ribbon;
    }

...这似乎有点臭。我的意思是，我必须重写 CreateRibbonExtensibilityObject（）不分;所有我做的超越所保持的本地引用色带，所以我可以调用的方法反对。但它并不适合我。是否有其他更好的方式来获得ThisWorkbook类中的参考？或者，这是很可以接受的？

...which seems a little smelly. I mean, I have to override CreateRibbonExtensibilityObject() regardless; all I'm doing beyond that is maintaining a local reference to the ribbon so I can call methods against it. But it doesn't feel right. Is there another, better way to get that reference in the ThisWorkbook class? Or is this pretty acceptable?

谢谢！

一个多简单的方法是什么地方创建一个全局静态变量（如的ThisWorkbook）

A much simpler way is to create a global static variable somewhere (e.g. in ThisWorkbook).

public static Ribbon ribbonref;

然后在功能区类的代码，在初始化事件的事件处理程序（我觉得方法被称为 Ribbon1_StartUp（），但我不知道），设置变量：

Then in the code of the Ribbon class, in the event handler for the initialization event (I think the method is called Ribbon1_StartUp() but I'm not sure), set the variable:

private void Ribbon1_StartUp(object sender, EventArg e)
{
    ThisWorkbook.ribbonref = this;
}

（从内存中这么写可能不完全正确）

(written from memory so may not be exactly right)

然后，您可以使用 ribbonref 来访问您的丝带实例。

You can then use ribbonref to access your ribbon instance.
