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
}

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

您可以使用这个非常试用的PowerShell命令从注册表中获取MSBuildToolsPath。

PowerShell(来自注册表)

Resolve-Path HKLM:\SOFTWARE\Microsoft\MSBuild\ToolsVersions\* | 
Get-ItemProperty -Name MSBuildToolsPath

输出

MSBuildToolsPath : C:\Program Files (x86)\MSBuild\12.0\bin\amd64\
PSPath           : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\12.0
PSParentPath     : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions
PSChildName      : 12.0
PSDrive          : HKLM
PSProvider       : Microsoft.PowerShell.Core\Registry

PSChildName      : 4.0
PSDrive          : HKLM
PSProvider       : Microsoft.PowerShell.Core\Registry

或者从文件系统

PowerShell(来自文件系统)

Resolve-Path "C:\Program Files (x86)\MSBuild\*\Bin\amd64\MSBuild.exe"
Resolve-Path "C:\Program Files (x86)\MSBuild\*\Bin\MSBuild.exe"

输出

Path
----
C:\Program Files (x86)\MSBuild\12.0\Bin\amd64\MSBuild.exe
C:\Program Files (x86)\MSBuild\14.0\Bin\amd64\MSBuild.exe
C:\Program Files (x86)\MSBuild\12.0\Bin\MSBuild.exe
C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe

最简单的方法可能是打开PowerShell并进入

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

本处地点

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

给出可执行文件的位置。

但如果你需要保存任务扩展的位置，它是打开的

%ProgramFiles%\MSBuild

对于Visual Studio 2017，在不知道确切版本的情况下，你可以在批处理脚本中使用:

FOR /F "tokens=* USEBACKQ" %%F IN (`where /r "%PROGRAMFILES(x86)%\Microsoft Visual 
Studio\2017" msbuild.exe ^| findstr /v /i "amd64"`) DO (SET msbuildpath=%%F)

findstr命令将忽略某些msbuild可执行文件(在本例中为amd64)。
