Bigger than 0

using System;

namespace ConsoleApplication1
{
class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Please enter a number");
        int userinput = Console.Read();
        if (userinput > 0) Console.Write("Bigger than 0");
            else if (userinput < 0) Console.Write("Less than 0");
                    else Console.Write("Equal to 0");
        Console.Write("\nPress <ENTER> to exit\n");
        Console.ReadKey();

        }

}
}

Answer 1

The Console.Read() method read the code of the key pressed, not an integer value typed in the console. You have to use Console.ReadLine() to read the full string and convert it into an integer, like this:

int userinput = Convert.ToInt32(Console.ReadLine());

Note that in case the input string won't be a proper integer number, the program will fail. You can consider using Int32.TryParse() and handling invalid input.
