PowershellScript ObjectNotFoundException CommandNotFoundException Path

Question

I sign my Dlls with SNK-Files. This is done without problems through the visual studio build.

Now i want to validate the DLLs that I really gave them a strong name. I found this powershell script, but I think powershell hates my path.

Clear-Host

$path="C:\Users\MyName\Desktop\BuildOutput\Debug"
$snPath = "C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\sn.exe"


foreach ($item in Get-ChildItem $path -Recurse -Include *.dll, *.exe)
{
    $reportLine = $item.FullName + "," + $item.Extension

#validate integrity
$expression = $snPath + ' -vf "' +  $item.FullName +'"'
$verify = Invoke-Expression $expression
$isValid = $verify | Select-String -Pattern "is valid"

if($isValid)
{
    $reportLine = $reportLine + ",ist signiert"
}
else
{
    $reportLine = $reportLine + ",ist nicht signiert"
}

#extract token
$expression = $snPath + ' -Tp "' +  $item.FullName +'"'
$result = Invoke-Expression $expression

$tokenString = $result | Select-String -Pattern "key token is"
if($tokenString)
{
    $token = $tokenString.Tostring().Substring(20)
    $reportLine = $reportLine + "," +$token
}

    $reportLine
} 

And my error is

In Line:1 Character:19

• C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 ...
• ~~~
  • CategoryInfo : ObjectNotFound: (x86:String) [], CommandNotFoundException
  • FullyQualifiedErrorId : CommandNotFoundException

I translated more error information.

The term "x86" was not recognized as the name of a cmdlet, function, script file, or executable. Check the spelling of the name, or if the path is correct (if included), and retry.

Do I have to escape the x86? And if yes - How can i do it? I tried this.

I tried this with allways the same result.

$snPath = "C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\sn.exe"

$snPath = ${env:CommonProgramFiles(x86)} + "\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\sn.exe"

$snPath =  ${env:ProgramFiles(x86)} + "\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\sn.exe"

$snPath = [Environment]::GetEnvironmentVariable("ProgramFiles(x86)") + + "\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\sn.exe"

EDIT

I fixed my snPath

I gave more examples

Answer 1

instead of

$expression = $snPath + ' -vf "' +  $item.FullName +'"'
$verify = Invoke-Expression $expression

you could do it like that:

$verify = & $snPath -vf $item.FullName
