使用 PowerShell 递归遍历 Visual Studio 解决方案 [英] Recursively traversing a Visual Studio Solution using PowerShell

问题描述

我需要以编程方式从包含近 150 个项目的解决方案中提取信息.虽然解决方案文件不是平面的，所以一些项目被组织到文件夹中，文件夹层次结构可以更深.这适合递归解决方案:我可以编写一个函数，它枚举一个列表，如果元素是一个项目，它会检查它，如果它是一个文件夹，它会进入文件夹并递归调用自身以检查文件夹的内容.要点:

I need to programatically extract information from a solution which contains almost 150 projects in it. The solution file is not flat though, so some of the projects are organized into folders, the folder hierarchy can be more levels deep. This fits a recursive solution: I could write a function, which enumerates a list, and if the element is a project it would examine it, if it is a folder it would go into the folder and recursively call itself to examine the folder's content. The gist of it:

$dte = [System.Runtime.InteropServices.Marshal]::GetActiveObject("visualstudio.dte.11.0")

function traverseproject {
    param([object]$prjnode, [int]$level)
    if ($prjnode.Kind -eq "{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}")
    {
        Write $prjnode.Name
        Write $level
    }
    if ($prjnode.Kind -eq "{66A26720-8FB5-11D2-AA7E-00C04F688DDE}")
    {
        foreach ($prjsubnode in $prjnode)
        {
            traverseproject($prjsubnode, $level + 1)
        }
    }
}

foreach($prjn in $dte.solution.projects)
{
    traverseproject($prjn, 0)
}

问题是递归函数得到的 $prjnode 对象很奇怪.Write $prjnode.Name 不输出任何内容.可能出于同样的原因，我无法遍历文件夹对象的节点.现在在上面的代码中，它是 foreach ($prjsubnode in $prjnode)，它不会默默地做任何事情.我试过 foreach ($prjnode.ProjectItems 中的 $prjsubnode)，它给出了错误.我尝试了任何组合.

The problem is that the $prjnode object what the recursive function gets is weird. Write $prjnode.Name doesn't output anything. Probably for the same reason I cannot iterate through the nodes of the folder object. Right now in the code above it's foreach ($prjsubnode in $prjnode), that just doesn't do anything silently. I tried foreach ($prjsubnode in $prjnode.ProjectItems), that gives error. I tried any kind of combinations.

从错误消息看来 $prjnode 是 DTE ProjectItem link, 8E2F1269-185E-43C7-8899-950AD2769CCF.我可以打印出 Count 属性，它似乎有效，但我在界面上看不到任何可以获取包含元素的属性.所以也许这就是我无法迭代的原因?不可能?我在链接的 MSDN 页面底部看到了 Visual Basic 示例，但我需要一个有效的 PowerShell 解决方案.

From the error messages it seems that the $prjnode is type of a DTE ProjectItem link, 8E2F1269-185E-43C7-8899-950AD2769CCF. I can print out the Count property and it seems valid, but I don't see any property on the interface where I could get a hold of the contained elements. So maybe that's why I cannot iterate through? There's no way? I see the Visual Basic example at the bottom of the MSDN page I linked, but I need a working PowerShell solution.

该函数的第一次调用似乎工作正常，例如它看到了 $prjnode.Kind 属性，但是在第一次递归调用之后，事情就丢失了.

The first call of the function seems to work OK, for example it sees the $prjnode.Kind property, but after the first recursive call things are lost.
