我在做这个（我认为会是）一个小而简单的任务时正在学习powershell。我真的不知道我哪里出错了，所以希望有人能指出我正确的方向。我只是想将一些项目添加到一个名为“All.sln”的解决方案中。我有以下代码：

[string]$slnName = "All"
[string]$baseDir = "SOMEDIR_OF_PROJECTS"
[string]$slnPath = (Join-Path $baseDir 'All.sln')

$dteObj = New-Object -ComObject "VisualStudio.DTE.10.0"
$solution = $dteObj.Solution
$solution.Create($baseDir, $slnName)
Write-Output "Solution Path: " $slnPath    

(ls $baseDir -Recurse *.vbproj) | % { 

     Write-Output $_.FullName
     $solution = $dteObj.Solution
     $solution.AddFromFile($_.FullName, $false) 
     $solution.SaveAs( $slnPath ) 
 }

Write-Output ( $slnPath )
$dteObj.Solution.SaveAs( $slnPath ) 
$dteObj.Quit()

我不断收到各种不同的错误，所以我的想法是我肯定在这里做错了什么，但对我来说我做错了什么并不明显。

我有时会收到此错误（通常在我尝​​试添加的第一个项目文件中）：

或者有时我得到（空？？）：

或者有时我得到（MethodNotFound??）：

在不了解有关 VisualStudio 及其“解决方案”的更多信息的情况下，我将给您一些通用的 PowerShell 建议：

  1. 永远不要假设你已经成功地获得了一个对象的句柄——你创建了你的$dteObj，然后假设实例化成功了。您需要将其包裹try...catch起来，例如：

    try {
    $dteObj = New-Object -ComObject "VisualStudio.DTE.10.0";
    blah
    blah
}
catch [Exception] {
    error handling
}

  2. 只是因为一个对象有一个属性，不要假设它是设置的。我建议检查解决方案属性不为空，例如：

    if ( $dteObj.Solution -ne $null ) {
    do something
} else {
    handle error state
}

  3. 如果一些代码不会引发异常，请使用 进行检查if ($?) {}，例如：

    $solution.SaveAs( $slnPath );
if ( ! $? ) {
    save failed
} else {
    save ok
}
