Creating and throwing new exception

Question

How I can create and throw a new exception in PowerShell?

I want to do different things for a specific error.

Answer 1

To call a specific exception such as FileNotFoundException use this format

if (-not (Test-Path $file)) 
{
    throw [System.IO.FileNotFoundException] "$file not found."
}

To throw a general exception use the throw command followed by a string.

throw "Error trying to do a task"

When used inside a catch, you can provide additional information about what triggered the error
