在安装vb.net期间添加连接字符串 [英] adding connection string during installation of vb.net

问题描述

这是我最后一个问题的后续跟进：在安装vb.net项目期间添加连接字符串

这是我到目前为止的代码，但配置in the line：

Dim config As Configuration = ConfigurationManager.OpenExeConfiguration（exePath）

我不能运行程序，因为它。我将C＃代码转换为那个，出现蓝线。我想在这里做的是获取一个字符串，我可以使用的连接字符串将由app.config使用。

导入系统。 ComponentModel

导入System.Configuration.Install

公共类InstallerClass

  Public Sub New（）
 MyBase.New（）
 
 
 InitializeComponent（）
 $ b b End Sub 
 
 
< RunInstaller（True）> _

继承安装程序

 Dim targetDirectory As String = Context.Parameters（targetdir ）
 
 Dim param1 As String = Context.Parameters（Param1）
 
 Dim param2 As String = Context.Parameters（Param2）
 
 Dim param3 As String = Context.Parameters（Param3）
 
 
 Dim exePath As String = String.Format（{0} MyWindowsFormsApplication.exe，targetDirectory）
 
 Dim config As Configuration = ConfigurationManager.OpenExeConfiguration（exePath）
 
 config.AppSettings.Settings（Param1）。Value = param1 
 
 config.AppSettings。设置（Param2）。Value = param2 
 
 config.AppSettings.Settings（Param3）。Value = param3 
 
 config.Save（）

解决方案

是我注意到的一些事情从你发布的代码：

• ConfigurationManager 来自 System.Configuration 命名空间， 配置 类，但您似乎没有 Imports System.Configuration （只有 Imports System.Configuration.Install ）...我会尝试添加一个 //msdn.microsoft.com/en-us/library/vstudio/wkze6zky%28v=vs.100%29.aspxrel =nofollow>参考到 System.Configuration 在安装程序项目中的程序集？ （对不起，我不记得它是否与这个程序集引用默认添加）




this is a follow up for my last question which is on: adding connection string during installation of vb.net project

this is the code that I have so far but the "Configuration" in the line:

Dim config As Configuration = ConfigurationManager.OpenExeConfiguration(exePath)

has a blue line and I can't run the program because of it. I converted the C# code to that one and the blue line appears. what I'm trying to do here is to get the a string that I can use for the connection string which will be used by the app.config.

Imports System.ComponentModel

Imports System.Configuration.Install

Public Class InstallerClass

Public Sub New()
    MyBase.New()


    InitializeComponent()

End Sub


<RunInstaller(True)> _
Partial Public Class MyInstaller
    Inherits Installer


    Partial Public Class MyInstaller
        Inherits Installer


        Public Overrides Sub Install(ByVal stateSaver As System.Collections.IDictionary)


            MyBase.Install(stateSaver)

            Dim targetDirectory As String = Context.Parameters("targetdir")

            Dim param1 As String = Context.Parameters("Param1")

            Dim param2 As String = Context.Parameters("Param2")

            Dim param3 As String = Context.Parameters("Param3")


            Dim exePath As String = String.Format("{0}MyWindowsFormsApplication.exe", targetDirectory)

            Dim config As Configuration = ConfigurationManager.OpenExeConfiguration(exePath)

            config.AppSettings.Settings("Param1").Value = param1

            config.AppSettings.Settings("Param2").Value = param2

            config.AppSettings.Settings("Param3").Value = param3

            config.Save()

        End Sub

    End Class




End Class

End Class

解决方案

I don't know if this is it but some things I have noticed from the code you have posted:

• ConfigurationManager comes from the System.Configuration namespace, as does the Configuration class but you don't seem to have Imports System.Configuration in your code (only Imports System.Configuration.Install)...I would try adding a Imports System.Configuration statement if you don't have this already

• Have you added a reference to the System.Configuration assembly in your installer project? (Sorry, I don't remember if it comes with this assembly reference added by default)
