Denna kod skulle må bra av lite tomma rader. Prova att lägga in en före och efter varje Console.Write som ligger utanför kodblock.

Här skulle man helt enkelt kunna återanvända input och integer utan att skapa nya variabler.

input = Console.ReadLine();
integer = Convert.ToInt32(input);


string waterLabel = integer1 >= 27 ? "Går att bada" : "Går inte att bada";
//if (integer1 >= 27)
//{
//Console.WriteLine("Går att bada");
//}
//else
//{
// Console.WriteLine("Det går inte att bada");
//}

switch (integer1)
{
case 1: waterLabel = "Går inte att bada alls"; break;
case -3: waterLabel = "Det är 3 minusgrader"; break;
}
Console.WriteLine(waterLabel + " i havet");

Variabelnamnet testvalue blir lite generellt i detta hänseende, fundera på om det finns något ännu tydligare.

Här konverteras number till int ytterligare en gång (som på rad 28).
För att undvika ineffektivitet i koden och att man behöver genomföra ändringar på flera ställen så nyttjar vi på Geta DRY-principen. Här kan man läsa mer om den.
