我尝试在 NuGet 控制台或 Power 控制台中使用 PowerShell 在 Visual Studio 中获取菜单条目。这些 PowerShell 主机在 Visual Studio 的上下文中运行。我到了某个地方，但还不够远...出现菜单条目（右键单击解决方案），但我无法连接事件处理程序...

我的代码：

PM> $sol = $DTE.CommandBars | Where-Object { $_.Name -like 'Solution' }
PM> $menuitem = $sol.Controls.Add([Microsoft.VisualStudio.CommandBars.MsoControlType]::msoControlButton, 1, "", 1, $true)
PM> $menuitem.Caption = "Action From NuGet"
PM> $menuItemHandler = $DTE.Events.CommandBarEvents($menuitem)
PM> $commandBarEvents = Get-Interface $menuItemHandler ([EnvDTE._dispCommandBarControlEvents_Event])
PM> $commandBarEvents.add_Click([EnvDTE._dispCommandBarControlEvents_ClickEventHandler]{Write-Host “Clicked”})
Cannot convert value "Write-Host “Clicked”" to type "EnvDTE._dispCommandBarControlEvents_ClickEventHandler". Error: "The type 'System.Boolean&' may not be used as a type argument."
At line:1 char:84
+ $commandBarEvents.add_Click([EnvDTE._dispCommandBarControlEvents_ClickEventHandler] <<<< {Write-Host “Clicked”})
    + CategoryInfo          : NotSpecified: (:) [], RuntimeException
    + FullyQualifiedErrorId : RuntimeException

PM>

最后一行给了麻烦......

我在 nuget.psm1 中由 nuget 本身执行的代码之后对此进行了模式化：

# Hook up Solution events

$solutionEvents = Get-Interface $dte.Events.SolutionEvents ([EnvDTE._dispSolutionEvents_Event])

$solutionEvents.add_Opened([EnvDTE._dispSolutionEvents_OpenedEventHandler]{
    ExecuteInitScripts
    UpdateWorkingDirectory
})

$solutionEvents.add_AfterClosing([EnvDTE._dispSolutionEvents_AfterClosingEventHandler]{
    UpdateWorkingDirectory
})

关于如何连接事件处理程序的任何想法？
