将app.config加载到AppDomain中 [英] Loading app.config into the AppDomain

问题描述

我无法将App.Config文件加载到App Domain中.

I can't get the App.Config file to load into the App Domain.

我正在使用

[System.AppDomain]::CurrentDomain.SetData("APP_CONFIG_FILE", $config_path)

来自使用App.config的Powershell调用.NET程序集

，但仍未加载App.Config文件.

from Powershell Calling .NET Assembly that uses App.config but the App.Config file is still not loaded.

我还尝试按照.

这是我的测试脚本:

$configFile = "{ActualPhysicalPath}\App.Config"
gc $configFile

Add-Type -AssemblyName System.Configuration
[Configuration.ConfigurationManager].GetField("s_initState", "NonPublic, Static").SetValue($null, 0)
[Configuration.ConfigurationManager].GetField("s_configSystem", "NonPublic, Static").SetValue($null, $null)
([Configuration.ConfigurationManager].Assembly.GetTypes() | where {$_.FullName -eq "System.Configuration.ClientConfigPaths"})[0].GetField("s_current", "NonPublic, Static").SetValue($null, $null)

[Configuration.ConfigurationManager]::ConnectionStrings[0].Name
[System.AppDomain]::CurrentDomain.SetData("APP_CONFIG_FILE", $null)
[Configuration.ConfigurationManager]::ConnectionStrings[0].Name
[System.AppDomain]::CurrentDomain.SetData("APP_CONFIG_FILE", $configFile)
[Configuration.ConfigurationManager]::ConnectionStrings[0].Name

我总是将连接字符串存储在machine.config中，而不是存储在App.config中.

I'm always getting the connection strings stored in machine.config, rather than those in the App.config.

如何将特定的App.Config文件加载到应用程序域中?

How can I get my specific App.Config file loaded in the app domain?

推荐答案

尝试将 SetData 语句移到 GetField 语句之前.

Try moving your SetData statement before the GetField statement.

在Windows 10上使用PowerShell 5.0，

With PowerShell 5.0 on Windows 10, the guidance provided by the link you reference seems to work: I'm able to retrieve both AppSettings and ConnectionStrings.

Add-Type -AssemblyName System.Configuration

# Set this to the full path of your App.config
$configPath = "C:\Full\Path\To\App.config"

[System.AppDomain]::CurrentDomain.SetData("APP_CONFIG_FILE", $configPath)
[Configuration.ConfigurationManager].GetField("s_initState", "NonPublic, Static").SetValue($null, 0)
[Configuration.ConfigurationManager].GetField("s_configSystem", "NonPublic, Static").SetValue($null, $null)
([Configuration.ConfigurationManager].Assembly.GetTypes() | where {$_.FullName -eq "System.Configuration.ClientConfigPaths"})[0].GetField("s_current", "NonPublic, Static").SetValue($null, $null)

[System.Configuration.ConfigurationManager]::AppSettings
[System.Configuration.ConfigurationManager]::ConnectionStrings
