在 Visual Studio 2017 DTE 中无法从 Powershell 控制台访问 FileCodeModel
Can't access FileCodeModel from Powershell console in Visual Studio 2017 DTE
我正在尝试使用集成的 Powershell 控制台和 VS 自动化模型 (DTE) 在 VisualStudio 2017 中自动化一些与代码相关的例程。当我在 Solution/Project/File 级别工作时,一切正常,例如
PS> $dte.ActiveDocument.ProjectItem
IsDirty : False
FileCount : 1
Name : FeaturesComposition.cs
Collection : System.__ComObject
Properties : System.__ComObject
DTE : System.__ComObject
Kind : {6BB5F8EE-4483-11D3-8BCF-00C04F8EC28C}
ProjectItems : System.__ComObject
Object : System.__ComObject
ExtenderNames : {}
ExtenderCATID : {610D4615-D0D5-11D2-8599-006097C68E81}
Saved : True
ConfigurationManager :
FileCodeModel : System.__ComObject
Document : System.__ComObject
SubProject :
ContainingProject : System.__ComObject
但是当我来到某个特定文件的代码模型时,没有任何东西可以使用:
PS> $dte.ActiveDocument.ProjectItem.FileCodeModel | Format-List -Property *
System.__ComObject
PS> $dte.ActiveDocument.ProjectItem.FileCodeModel | gm
PS>
是否可以访问此类子模型?有什么简单的方法可以将 EnvDTE.DTE 接口分派到现有的 $dte 实例吗?我尝试了下面的一些想法,但没有成功。
Add-Type -Path "$env:VSAPPIDDIR\PublicAssemblies\envdte.dll"

试试这个:
$fileCodeModel = Get-Interface $dte.ActiveDocument.ProjectItem.FileCodeModel ([ENVDTE80.FileCodeModel2])
