VB.NET中模块和表单之间的数据交换 [英] Data exchange between module and form in VB.NET

问题描述

我写了一些代码来读取fileconfig的内容。

它位于一个表单中。

我想，一旦数据被提取，插入它们form1中的列表框



这是代码



我尝试过的方法：

I wrote some code to read the contents of the fileconfig.
This resides in a form.
I would like, once the data is extracted, insert them in a listbox in the form1

this is the code

What I have tried:

Module ModuloConfig

    Sub MainConfig()
        ReadAllSettings() ' legge tutto il contenuto dell' app setting
     end sub  

    Sub ReadAllSettings() ' legge tutto l' appsetting
        Try
            Dim appSettings = ConfigurationManager.AppSettings

            If appSettings.Count = 0 Then
                Console.WriteLine("AppSettings is empty.") ' è vuoto
            Else
                For Each key As String In appSettings.AllKeys 'legge tutte le key
                    Console.WriteLine("Key: {0} Value: {1}", key, appSettings(key))

                Next
            End If
        Catch e As ConfigurationErrorsException
            Console.WriteLine("Error reading app settings")
        End Try
    End Sub
End Module

推荐答案

请按照： ListBox.ObjectCollection.Add（Object）方法（System.Windows.Forms）| Microsoft Docs [ ^ ]

我的问题不是创建一个列表框，而是将表单中的数据传输到表单中的列表框。也许通过函数调用



i想要传输这个：

my problem is not to create a list box but to transfer the data I got in the form to the listbox that is in the form. Maybe through a function call

i want to trasfert this:

key, appSettings(key)
