你也可以把MSBuild.exe的路径打印到命令行:

reg.exe query "HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0" /v MSBuildToolsPath

如果你想在。net 4中使用MSBuild，那么你可以使用下面的PowerShell命令来获取可执行文件的路径。如果您想要2.0或3.5版本，只需更改$dotNetVersion变量。

要运行可执行文件，您需要在$msbuild变量前面加上&。这将执行变量。

# valid versions are [2.0, 3.5, 4.0]
$dotNetVersion = "4.0"
$regKey = "HKLM:\software\Microsoft\MSBuild\ToolsVersions\$dotNetVersion"
$regProperty = "MSBuildToolsPath"

$msbuildExe = join-path -path (Get-ItemProperty $regKey).$regProperty -childpath "msbuild.exe"

&$msbuildExe

为https://github.com/linqpadless/LinqPadless/blob/master/build.cmd添加vwhere分支，在我的计算机上运行良好，vwhere分支在我伴侣的计算机上运行良好。 也许，vswhere分支应该作为第一个检查向前移动。

您可能认为这里没有太多需要添加的内容，但也许现在是时候在所有版本中使用统一的方式来执行此操作了。我将注册表查询方法(VS2015及以下)与vwhere (VS2017及以上)的使用结合起来，得出了这样的结果:

function Find-MsBuild {
    Write-Host "Using VSWhere to find msbuild..."
    $path = & $vswhere -latest -requires Microsoft.Component.MSBuild -find MSBuild\**\Bin\MSBuild.exe | select-object -first 1

    if (!$path) {
        Write-Host "No results from VSWhere, using registry key query to find msbuild (note this will find pre-VS2017 versions)..."
        $path = Resolve-Path HKLM:\SOFTWARE\Microsoft\MSBuild\ToolsVersions\* |
                    Get-ItemProperty -Name MSBuildToolsPath |
                    sort -Property @{ Expression={ [double]::Parse($_.PSChildName) }; Descending=$true } |
                    select -exp MSBuildToolsPath -First 1 |
                    Join-Path -ChildPath "msbuild.exe"
    }

    if (!$path) {
        throw "Unable to find path to msbuild.exe"
    }

    if (!(Test-Path $path)) {
        throw "Found path to msbuild as $path, but file does not exist there"
    }

    Write-Host "Using MSBuild at $path..."
    return $path
}

翻了翻登记表，看起来

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\2.0
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\3.5
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0

也许是你想要的;打开regedit.exe，看一看。

通过命令行查询(由Nikolay Botev提供)

reg.exe query "HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0" /v MSBuildToolsPath

通过PowerShell查询(每个MovGP0)

dir HKLM:\SOFTWARE\Microsoft\MSBuild\ToolsVersions\

从MSBuild 2017 (v15)开始，MSBuild现在安装在每个Visual Studio版本下的文件夹中
