C#.NET — Determine switch output when switching on an enum value. namespace CuriousTabConsoleApplication { public enum color { red, green, blue }; class SampleProgram { static void Main(string[] args) { color c = color.blue; switch (c) { case color.red: Console.WriteLine(color.red); break; case color.green: Console.WriteLine(color.green); break; case color.blue: Console.WriteLine(color.blue); break; } } } }

Introduction / Context:This question checks how enums print when written to the console and confirms correct case matching in a switch statement over an enum.

Given Data / Assumptions:

• Enum color { red, green, blue } with implicit values 0, 1, 2.
• Variable c is assigned color.blue.
• Each switch case prints the enum member.

Concept / Approach:Console.WriteLine on an enum value writes the identifier name by default (not the underlying numeric value), unless formatted otherwise. Matching case color.blue triggers printing of "blue".

Step-by-Step Solution:

Verification / Alternative check:If you cast to int, e.g., (int)color.blue, you would see 2. Without casting, the name is printed.

Why Other Options Are Wrong:

• "red" and numeric outputs 0/1/2 do not occur because the code prints the identifier, not the underlying integer.
• "blue" is the only branch that runs.

Common Pitfalls:Assuming enums print as numbers by default or believing switch falls through and prints multiple lines (it does not due to break statements).

Final Answer:blue
