获取对申请家长表格的引用 [英] Getting a Reference to Application Parent Form

问题描述

是否有人知道有关如何实现以下目标的任何标准或白皮书:

我有一个项目，该项目具有一个名为myForm的表单和一个名为ClassA的类.在ClassA中，我有一个名为CreateButton的方法，该方法通过代码创建Button类的实例.问题是:由于ClassA没有对myForm的引用，如何将这个Button对象添加到Controls集合中?
我知道我可以将对myForm的引用传递给ClassA的构造函数，但我不希望此类对myForm有所了解.基本上，我不希望该类与表单一起使用.

我知道我可以使用委托来完成此操作，但是如果我的类创建其他类型的控件，则必须为每种类型都有一个委托，这绝对不是一个好的解决方案.

Does any one know of any standards or white papers on how to accomplish the following:

I have a project with a form called myForm, and a single class called ClassA. Within ClassA I have a method called CreateButton, which creates an instance of Button Class via code. The question is: how do I add this Button object to the Controls collection since the ClassA does not have a reference to myForm?

I know that I could pass a reference to myForm to the constructor of ClassA, but I do not want this class to know anything about myForm. Basically I do not want that class to be coupled with the form.

I know I could use a delegate to accomplish this, but if my class creates other types of controls it would have to have a delegate for each type, which is definetly not a good solution.

Does any one knows what is the right way of doing something like this?

推荐答案

0)您可以通过构造函数将对表单的引用传递到ClassA中.

1)您可以设置一个全局静态类，其中包含对表单的(公共)引用，并仅使用ClassA中的引用即可.

0) You could pass a reference to the form into ClassA via the constructor.

1) You could setup a global static class that holds a (public) reference to the form and just use that from ClassA.
