Spaces in path throwing error when using ArgumentList parameter of Start-Process [duplicate]

Question

In my profile I've got the following function:

function Start-VS {  
  param ([string]$sln, [switch]$UseNineteen )

  if ($UseNineteen) {
    $vs = "c:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\devenv.exe"
    $vsWorkDir = "c:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\"
  }
  else {
    $vs = "C:\Program Files\Microsoft Visual Studio\2022\Preview\Common7\IDE\devenv.exe"
    $vsWorkDir = "C:\Program Files\Microsoft Visual Studio\2022\Preview\Common7\IDE\"  
  }
  
  if (-Not ([string]::IsNullOrEmpty($sln))) {
    $TestP = (Test-Path $sln)
    if ( $TestP -eq $True) {
      $FullPath = Convert-Path $sln
      Start-Process $vs -WorkingDirectory $vsWorkDir -ArgumentList $FullPath  
    }
    else {
      Write-Output $FullPath
      Write-Output "Please use a correct pathway to a solution file" 
    }
  }
  else {
    Start-Process $vs -WorkingDirectory $vsWorkDir 
  }
}

To call it from the PS prompt I'm doing the following:

start-vs -sln "C:\demos\m02 arrays\Example.sln"

Visual studio opens but complains that it cannot find the files - I understand it is because of the space in m02 arrays - how do I alter the function so that it can handle spaces?

Answer 1

Change

Start-Process $vs -WorkingDirectory $vsWorkDir -ArgumentList $FullPath

to

Start-Process $vs -WorkingDirectory $vsWorkDir -ArgumentList "`"$FullPath`""

Notice the escaped "s surrounding $FullPath. This will include the surrounding quotes to be sent as part of the argument which is needed for paths (or other strings) that include spaces
