Question

I use trap to write errors to file, and want write line number where error ocured.

$_.Exception.StackTrace is not answer.

Where I can get line number of error? Maybe some predefined variable?

Answer 1

You can retrieve the line number from the InvocationInfo object on $_. For example, the script…

"Hello, World!"

function foo() {
  trap [Exception] {
    $_.InvocationInfo.ScriptLineNumber
    $_.InvocationInfo.OffsetInLine
    continue;
  }

  [reflection.assembly]::loadfrom("C:\")
}

foo

… generates the output:

Hello, World!
