无法在模块的类中声明具有公共访问权限的变量 [英] Cannot declare a variable with public access in a class from a module

问题描述

我正在制作一个基于 GUI 的应用程序(表单)，但遇到以下错误.

I am making a GUI based application (forms), and encountered the following error.

首先，我在模块中声明以下内容

Firstly, I am declaring the following stuff in a module

Module test_mod

    Public Structure sub_struct
        Public test_int() As Integer
        Public Sub foo()
            ReDim test_int(3)
        End Sub
    End Structure

    Public Structure main_struct
        Public test_aaa As sub_struct
    End Structure

End Module

当然，我的实际代码比这更长更复杂，但这段代码将是一个完美的例子.

Of course, my real code is longer and more complicated than this, but this piece of code will be a perfect example.

然后我在主类中声明这个test_mod

Then I declare this test_mod in the main class

Public Class Form1
    Public test_this_struct As New test_mod.main_struct
    'do something here
End class

我的目的是让 test_this_struct 可以被其他模块(这里没有显示)访问，这样主类就会简短而整洁.但是，它不断抱怨以下内容:test_this_struct 不能通过类 form1 在项目外暴露类型 test_mod.main_struct.

My intention is making the test_this_struct accessible by other modules (which are not shown here), such that the main class will be short and tidy. However, it keeps complaining the following: test_this_struct cannot expose type test_mod.main_structoutside the project through class form1.

我在这里没有看到任何 Private，我厌倦了删除 new、redim 和struct in struct"，但是他们没有工作.

I do not see any Private here, and I tired to remove the new, redim, and "struct in struct", but they did not work.

我在 MSDN 上找到了一篇文章及其相关内容，但是它并没有真正帮助我.

I found an article and its related content on MSDN, but it did not really help me.

推荐答案

试试这个:

Public Module test_mod
    Public Structure sub_struct
        Public test_int() As Integer

        Public Sub foo()
            ReDim test_int(3)
        End Sub
    End Structure

    Public Structure main_struct
        Public test_aaa As sub_struct
    End Structure
End Module
