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

User · Answer

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

You can throw your own custom errors by extending the Exception class  class CustomException   Exception        string   additionalData      CustomException  Message   additionalData    base  Message             this additionalData    additionalData          try       throw  CustomException   new  Error message    Extra data     catch  CustomException          NOTE  To access your custom exception you must use    Exception     Write-Output    Exception additionalData        This will produce the error message  Didn t catch it the second time     throw  CustomException   new  quot Didn t catch it the second time quot    Extra data
