Console.Read failure in C#

Question

This is a very simple bit of code. But it is the first time I have written a console app in C#. To put it simply, Using these two lines

    int iRoll;
    Console.WriteLine("Roll Dice and input number for your move");
    iRoll = Console.Read();

and if I enter the number 5 from the cmd window (it does not matter if it is from the number pad or the keyboard) the value for iRoll is 53. Why is this?

`int.TryParse(Console.ReadLine(), out iRoll);` – mybirthname Dec 02 '16 at 12:53 — mybirthname, Dec 02 '16 at 12:53

Console.Read returns an int containing the character read from the input stream. The character 5 is encoded as 53.

If you want a string containing the line you should use ReadLine instead:

string line = Console.ReadLine();

You can then parse the string into an int using int.TryParse:

int iRoll;
if (int.TryParse(line, out iRoll)) {
    // use iRoll
} else {
    // handle invalid input
}

This is too easy a fix and a repeat. Who seconds my motion to delete it? – xarzu Dec 02 '16 at 13:53

This is because you read the ASCII code of '5' char. This is 53 value .
