this is my program that i wrote in C# in visual studio 2010 Ultimate and 2008 Team System:

class Program
{
    static void Main(string[] args)
    {
        int a=0;
        Console.WriteLine("Enter a number: ");
        a = Console.Read();
        Console.WriteLine("you Entered : {0}",a);
        Console.ReadKey();
     }
}

And this is the result:

Enter a number: 5 you Entered : 53

How this possible?

As the documentation clearly states, Read() returns the index of the Unicode codepoint that you typed.

  • The documentation also gives an example of running the return value through `Convert.ToChar`. – jltrem Oct 16 '13 at 20:25
  • I don't see "Unicode" anywhere in that page. So the Unicode part must come from the fact that c# does everything in Unicode. – gunr2171 Oct 16 '13 at 20:45

The behavior you observed is described in the documentation.

Converted to a character code. Try:

a = int.Parse(Console.ReadLine());

Try this to reach your goal:

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Enter a number: ");
        ConsoleKeyInfo a = Console.ReadKey();
        Console.WriteLine("you Entered : {0}",a.KeyChar);
        Console.ReadKey();
     }
}

I'm new to C#, but as far as I know, it's unnecessary to initialize your variable a when you create it. Another way to write your code could be:

class Program
{
    static void Main(string[] args)
    {
        int a;
        Console.WriteLine("Enter a number: ");
        a = Convert.ToInt32(Console.ReadLine());
        Console.WriteLine("you Entered : {0}", a);
        Console.ReadKey();
     }
}
