The Windows Forms application will be used by regional offices of Domain.com in various countries.

You additionally are required to identify the .Net Framework class that should be used for this requirement.
What should you do?

The CultureInfo class should be used

B.
The TextInfo class should be used

C.
The DateTimeFormtaInfo should be used

D.
The CharUnicodeInfo should be used

Explanation:
The CultureInfo class should be used in the scenario because it contains culture- specific information and
provides the information required for performing culture-specific operations like changing casing, formatting dates and
numbers and comparing strings.
Incorrect Answers:

preferences of the user and does not depend upon the culture.
