您应该创建一个单独的静态类来保存您的数据信息，以使其与Form类分开.这样，您创建的任何UI类都将能够获取数据.如果您的数据对象包含在一个表单类中，那么解决方案的设计就很简单.

You should create a separate static class that holds your data information so that it is separate from your Form classes. That way, any UI class you create will be able to get at the data. If your data object is included in one of the form classes, then there is quite simply a problem with the design of the solution.
