It is accessible only in advanced functions via the $PSCmdlet variable.
ThrowTerminatingError() is a method that comes directly from PowerShell's PSCmdlet. Next, we have a more advanced version of the throw statement. There is no guarantee a user will not elect to simply ignore your error with -ErrorAction Ignore and continue with their lives if it is passed up from your functions. Throw should generally be used for simple runtime errors, where you need to halt execution, but typically only if you plan to catch it yourself later. Throw exceptions are affected by -ErrorAction parameters of their advanced functions. The line number and position displayed from a throw error message point back to the throw statement itself. Its exceptions display the entered error message, a generic RuntimeException, and the errorID matches the entered exception message. Throw creates an exception and an ErrorRecord (PowerShell's more detailed version of an exception) in a single, simple statement, and wraps them together. Throwįirst is your typical throw statement, which simply takes an exception message as its only input. There are a couple different ways to get a terminating error in PowerShell, and each has its own small differences that make them more useful in a tricky situation. Return control to the caller, along with the exception, if they're not handled using a try/catch block.Their common characteristics are as follows: They're very similar to C#'s Exception system, although PowerShell uses ErrorRecord as its base error object. Terminating errors are mostly an "exactly what it sounds like" package in general use. Different Types of Errors Terminating Errors
Let's have a look at some ways to effectively utilise the different kinds of errors you can work with in PowerShell, and how to handle them.
There are always two sides to consider, too: how you write code that creates errors, and how you handle those errors in your own code. There are a few different kinds of errors in PowerShell, and it can be a little bit of a minefield on occasion.
