A positional parameter cannot be found that accepts argument '[System.Convert]::ToBase64String'

Question

While I am running the below command, I am getting error "Get-Content: A positional parameter cannot be found that accepts argument '[System.Convert]::ToBase64String'."

What could be the issue?

# [Powershell]
# Get content of certificate as byte stream, and convert to base64 string and store in .txt
$fileContentBytes = get-content ‘certificate.pfx' -AsByteStream [System.Convert]::ToBase64String($fileContentBytes) | Out-File ‘pfx-encoded-bytes.txt’

Answer 1

Put the expression "[System.Convert]::ToBase64String($fileContentBytes)" within parentheses. I.e.

( [System.Convert]::ToBase64String($fileContentBytes) )
