Pull request overview
Updates the C# snippet sources used by the .NET API reference docs for System.String (and System.StringComparer) to align with the ongoing “modernize all C# code snippets” effort (issue #12713).
Changes:
- Modernizes C# syntax across snippets (e.g.,
stringkeyword, target-typednew(), string interpolation, simplified type names). - Cleans up formatting and minor style consistency (indentation, spacing, some unused
usingremovals). - Keeps snippet outputs/comments aligned with the updated code formatting.
