如何在PowerShell中使用DTE？ [英] How to use DTE in PowerShell?

问题描述

我想使用PowerShell来自动创建基于种子的n层解决方案的过程中（想想EDMX文件或的DbContext）配置。我希望能够打开一个骨架的解决方案，得到了积极的实例，并填充项目文件自动生成的code。

I am trying to use PowerShell to automate the process of creating an n-tier solution based on a seed (think EDMX file or DbContext) configuration. I want to be able to open a skeleton solution, get the active instance, and populate project files with auto-generated code.

我想C中的示例中提供跨$ C $这里 PowerShell的，但是，我得到的错误。

I'm trying to transcode the example provided here to powershell, however, I am getting errors.

下面是PowerShell的code我测试：

Here is the PowerShell code I am testing:

首先，我执行一个小功能来引用DTE组件。

First, I execute a little function to reference the DTE assemblies.

$libs = "envdte.dll", "envdte80.dll", "envdte90.dll", "envdte100.dll"
function LoadDTELibs {
    param(
        $path = "\Microsoft Visual Studio 10.0\Common7\IDE\PublicAssemblies"
    )

    Process {
        $libs |
            ForEach {
                $dll = Join-Path "$env:ProgramFiles\$path" $_

                if(-not (Test-Path $dll)) {
                    $dll = Join-Path "${env:ProgramFiles(x86)}\$path" $_
                }

                Add-Type -Path $dll -PassThru | Where {$_.IsPublic -and $_.BaseType} | Sort Name
            }
    }
}


LoadDTELibs

于是，我尝试创建一个对象引用调用的结果 [System.Runtime.InteropServices.Marshal] :: GetActiveObject（VisualStudio.DTE.11.0）

PS> $dte = New-Object -ComObject EnvDTE80.DTE2

New-Object : Retrieving the COM class factory for component with CLSID {00000000-0000-0000-0000-000000000000} failed due to the following error: 80040154 
Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).
At line:1 char:8
+ $dte = New-Object -ComObject EnvDTE80.DTE2
+        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ResourceUnavailable: (:) [New-Object], COMException
    + FullyQualifiedErrorId : NoCOMClassIdentified,Microsoft.PowerShell.Commands.NewObjectCommand

或

PS> $dte = New-Object EnvDTE80.DTE2

New-Object : Constructor not found. Cannot find an appropriate constructor for type EnvDTE80.DTE2.
At line:1 char:8
+ $dte = New-Object EnvDTE80.DTE2
+        ~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (:) [New-Object], PSArgumentException
    + FullyQualifiedErrorId : CannotFindAppropriateCtor,Microsoft.PowerShell.Commands.NewObjectCommand

最后，这也不行：

Finally, this does not work either:

PS> [EnvDTE80.DTE2]$dte = [System.Runtime.InteropServices.Marshal]::GetActiveObject("VisualStudio.DTE.11.0")

Cannot convert the "System.__ComObject" value of type "System.__ComObject#{04a72314-32e9-48e2-9b87-a63603454f3e}" to type "EnvDTE80.DTE2".
At line:1 char:1
+ [EnvDTE80.DTE2]$dte = [System.Runtime.InteropServices.Marshal]::GetActiveObject( ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : MetadataError: (:) [], ArgumentTransformationMetadataException
    + FullyQualifiedErrorId : RuntimeException

所以，我的问题是，你如何使用DTE从PowerShell的？更具体地讲，你怎么投致电GetActiveObject键入EnvDTE.DTE2的结果？

So, my question is, how do you use DTE from PowerShell? More specifically, how do you cast the result of calling GetActiveObject to type EnvDTE.DTE2?

推荐答案

我发现了一个简单的答案用的想法，在ISE玩了一会儿。

I found a simple answer by playing with the idea in ISE for a little while.

基本上，调用GetActiveObject返回一个COM对象，它可以在PowerShell中直接使用。执行LoadDTELibs后，您可以通过调用GetActiveObject得到DTE的一个实例，然后直接引用的结果。

Basically, the call to GetActiveObject returns a COM object, which can be used directly in PowerShell. After executing LoadDTELibs, you can get an instance of DTE by calling GetActiveObject and then refer to the result directly.

所以...

PS> $dte = [System.Runtime.InteropServices.Marshal]::GetActiveObject("VisualStudio.DTE.11.0")

然后：

PS> $dte.solution.Create("D:\Testing", "Acme.sln")
PS> $dte.solution.SaveAs("D:\Testing\Acme.sln")

我不是100％肯定，因为我不知道的PowerShell或COM那么好，但我觉得你真的不担心释放COM实例。

I'm not 100% sure, because I don't know PowerShell or COM all that well, but I think you don't really have to worry about releasing the COM instance.
