CmdletProvider.ShouldProcess Method (String, String)
Updated: April 27, 2016
Applies To: Windows PowerShell
Confirms the operation with the user, sending the name of the resource to be changed and the action to be performed to the user for confirmation before the operation is performed.
Assembly: System.Management.Automation (in System.Management.Automation.dll)
The name of the resource to be changed.
The action to be taken.
The pipeline is stopped. The pipeline was terminated either before the call was made or while the call was in progress. In general, the Windows PowerShell provider should allow the caller of the processing record method to catch this exception.
Also, if the pipeline was terminated because of ActionPreference.Stop or ActionPreference.Inquire, the command failure will ultimately be ActionPreferenceStopException.
When the provider calls the ShouldProcess(String, String, String) method, the Windows PowerShell runtime handles any command-line settings or preference variables when it determines what is shown to the user or what should be returned.
Windows PowerShell provides two methods that the Windows PowerShell provider can call to confirm an operation with the user: ShouldProcess and ShouldContinue. The second method, the ShouldContinue method, is used to get a confirmation from the user in cases where the change is significant or when you want to provide yes-to-all and no-to-all options to the user. In addition, in contrast to ShouldProcess calls, a call to ShouldContinue is not affected by command-line settings or preference variables; the query is always displayed to the user.
