if,return method

Song Lee

Hi, I was wondering if there a way to make it so if something other than int or double is input, it gives an error message.

This is what I got so far:

public static void FirstInput()

{
Console.WriteLine("F to C");
Console.Write("Enter number : ");
double.TryParse(Console.ReadLine(), out fromF);

}

//and below is the coding that I got from a friend

Is there a way to integrate those two codes?

if (int.tryParse(Console.ReadLine(), out res))

return res;

console.WriteLine("Error, can't convert, try again");

return GetInteger();

Thank you!
