Want to know how to delete the fieldlinks for the content type.

        Write-Host "Deleted Redundant ACL Columns from List " $list " for 
         web " $web.title

        $sitecols = @{"BU" = "BU"; "Discipline" = "Discipline";}

        $cttypes = @("Memo","Model")

        foreach ($cttype in $cttypes)
            $cttypeo = $list.contenttypes[$cttype]


I am trying to apply the above code for deleting the List Content Type association for my Document Library.But somehow its not working.What I am missing here? After executing this script I am still able to see the list content type association still exists!


You should update your content type using $cttype.Update() in your foreach sequense after field link deletion

  • I added the code for updation.But that update method gave me error it has been modified by another user. Jun 4 '15 at 7:51

    Use a for loop instead of foreach.

  • Yeah, @Bunzab could be correct, because your content type collection is modified and foreach statement fails. Possibly, that's why you get error.
