ROSLYN.PERFORMANCE.CA1861 : Avoid constant arrays as arguments (C#)

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

ROSLYN.PERFORMANCE.CA1861 : Avoid constant arrays as arguments (C#)

Summary

Constant arrays passed as arguments are not reused when called repeatedly, which implies a new array is created each time. Consider extracting them to 'static readonly' fields to improve performance if the passed array is not mutated within the called method.

This check corresponds to Roslyn rule CA1861. For full rule details, see the Microsoft website: CA1861.
