Hello, All

I have made specific validation of input parameters in my cmdlet:

protected override void BeginProcessing() { if (File.Exists(Output)) { var message = string.Format("File '{0}' already exists. Do you want to remove it?", Output); var result = this.ShouldContinue(message, "File exists"); if (result) { File.Delete(Output); } else { //TODO: Stop cmdlet execution and exit } } // Another validation code } protected override void ProcessRecord() ...

And I want to stop cmdlet execution (in place marked as TODO) and abort execution of ProcessRecord method. How can I do it?

Maybe Cmdlet SDK have special method for abort cmdlet execution...

Thanks

I haven't had any experience with Cmdlet development, but I can take a couple of guesses:

- There is a StopProcessing() method (http://msdn.microsoft.com/en-us/lib....85).aspx) and a Stopping property (http://msdn.microsoft.com/en-us/library/system.management.automation.cmdlet.stopping(v=VS.85).aspx) that you can maybe use.

- You can throw a FileNotFoundException which will stop the execution of your code.

The StopProcessing is empty virtual method (see http://img683.imageshack.us/img683/2448/stopprocessing.png). The Stopping is read-only property. Therefore this way don't work.

Also I don't want to throw exception because I don't want to see exception message in PowerShell window when user abort cmdlet execution.

But thanks for your answer.

I guess you could set a boolean flag and return from the method, then evaluate the boolean flag in the ProcessRecord() method and do the neccessary processing depending on the value.
