我正在尝试在 PowerShell ISE 中使用 .NET 4.0 程序集，并尝试更改通过以下方式使用的配置文件：
[System.AppDomain]::CurrentDomain.SetData("APP_CONFIG_FILE", $PathToConfig);
[Configuration.ConfigurationManager]::ConnectionStrings.Count 总是返回“1”，
而“[Configuration.ConfigurationManager]::ConnectionStrings[0].Name”总是返回“LocalSqlServer”，并且那个 ConnectionString 名称不在我的“.config”中文件。
请注意，从 PowerShell 命令提示符执行 PowerShell 脚本会按预期运行。只是当我从 PowerShell ISE 中执行它时，它没有按预期工作。
It's because the path to app.config for PowerShell ISE has already been loaded and cached so changing the app.config path afterwards won't make a difference: stackoverflow.com/q/6150644/222748
Here is an example script that will clear the cached path so it will work under PowerShell ISE:
[System.AppDomain]::CurrentDomain.SetData("APP_CONFIG_FILE", $PathToConfig)
Add-Type -AssemblyName System.Configuration
[Configuration.ConfigurationManager].GetField("s_initState", "NonPublic, Static").SetValue($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, $null)
[Configuration.ConfigurationManager]::ConnectionStrings[0].Name
起飞[0]对我有用。
([Configuration.ConfigurationManager].Assembly.GetTypes() | where {$_.FullName -eq "System.Configuration.ClientConfigPaths"}).GetField("s_current", "NonPublic, Static").SetValue($null, $null)
