Experiment with C#'s Case Statements

Context

From Google's AI's response
In C#, while traditional switch statements only allow discrete constant values for case labels, you can effectively handle ranges of options using several techniques, especially with newer C# features:

1. switch statement with when clauses (C# 7.0 and later):
   This allows you to add a conditional expression to a case label, effectively creating a range check.
   int score = 75;
string grade = score switch
{
int s when s >= 90 => "A",
int s when s >= 80 => "B",
int s when s >= 70 => "C",
int s when s >= 60 => "D",
_ => "F"
};
Console.WriteLine($"Score: {score}, Grade: {grade}");
2. if-else if statements:
   This is a classic and straightforward approach for handling sequential ranges.
   int temperature = 25;
if (temperature >= 30)
{
Console.WriteLine("Hot!");
}
else if (temperature >= 20)
{
Console.WriteLine("Warm.");
}
else if (temperature >= 10)
{
Console.WriteLine("Mild.");
}
else
{
Console.WriteLine("Cold!");
}
3. switch expressions (C# 8.0 and later):
   This provides a more concise syntax for pattern matching, including range-based conditions.
   int age = 15;
string ageGroup = age switch
{
int a when a < 13 => "Child",
int a when a >= 13 && a < 18 => "Teenager",
int a when a >= 18 && a < 65 => "Adult",
_ => "Senior"
};
Console.WriteLine($"Age: {age}, Age Group: {ageGroup}");

Goal

Experiment with the above options to learn how to use them and implement the one which I like the best or performs the best in the application.

Acceptance Criteria: Demonstrate Performance testing of the three options above. Journal about the performance, experience, and preference. The final preference is implemented in code and PR'd into the main branch.

This could be a way of implementing this code that I'm saving from adding to the code until I have Unit Tests written. This could have been a separate feature branch, but it's late and I'm tired. I'll address this in a future session.

return now switch
{
    DateTime d when d < noon => "Morning",
    DateTime d when d < evening => "Afternoon",
    _ => "Evening"
};
