ROSLYN.PERFORMANCE.CA1802 : Use literals where appropriate (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.CA1802 : Use literals where appropriate (C#)

Summary

A field is declared static and read-only (Shared and ReadOnly in Visual Basic), and is initialized by using a value that is computable at compile time. Because the value that is assigned to the targeted field is computable at compile time, change the declaration to a const (Const in Visual Basic) field so that the value is computed at compile time instead of at runtime.

This check corresponds to Roslyn rule CA1802. For full rule details, see the Microsoft website: CA1802.
