I get ticked about not having inline switch in c#

SwitchExtensions.cs

public static class SwitchExtensions
{
	public static TReturn Switch<TInput, TReturn>(this TInput input, params (Predicate<TInput> check, Func<TInput, TReturn> value)[] cases) =>
		Switch(input, c => default, cases);

	public static TReturn Switch<TInput, TReturn>(this TInput input, Func<TInput, TReturn> defaultCase, params (Predicate<TInput> check, Func<TInput, TReturn> value)[] cases) =>
		cases
		.Concat(new (Predicate<TInput> check, Func<TInput, TReturn> value)[] { (c => true, defaultCase) })
		.First(c => c.check(input))
		.value(input);
}

public static class Example
{
	public static string GetTens(int toCheck) => toCheck.Switch(
		defaultCase: i => "Something bigger than 100!",
		(i => i >= 0 && i < 10, i => "Zeroes"),
		(i => i > 10 && i < 20, i => "Tens"),
		(i => i > 20 && i < 30, i => "Twenties"),
		(i => i > 30 && i < 40, i => "Thirties"),
		(i => i > 40 && i < 50, i => "Forites"),
		(i => i > 50 && i < 60, i => "Fifties"),
		(i => i > 60 && i < 70, i => "Sixties"),
		(i => i > 70 && i < 80, i => "Seventies"),
		(i => i > 80 && i < 90, i => "Eighties"),
		(i => i > 90 && i < 100, i => "Nineties")
	);
}
