C# : Console.Read() does not get the "right" input

I have the following code: The actual problem is the "non-quoted" code. I want to get the player amount (max = 4), but when I ask via Console.Read() and I enter any Int from 1 to 4 I get as value: 48 + Console.Read(). They only thing how I can get the "real" input is using Console.ReadLine(), but this does not give me an Integer, no it returns a string, and actually do not know how to convert String (Numbers) to Integers in C#, because I am new, and because I only found ToString() and not ToNumber.

You can use

int convertedNumber = int.parse(stringToConvert)

or

int convertedNumber;

int.TryParse(stringToConvert, out covertedNumber)

to convert strings to integers.

You should really use TryParse instead so that you can catch if the user doesn't input a number. int.Parse will throw an exception if it tries to convert a string that is not numeric.

 int convertedNumber = 0;

 if (!int.TryParse(stringToConvert, out convertedNumber))
 {
     // this code will execute if the user did not put
     //     in an actual number.  For example, if the user entered "a".
 }

The TryParse method returns a boolean value which will tell you whether the conversion was successful. If it was successful, the converted value will be passed through the out parameter.

To convert your string to an integer, use int.Parse(yourString).

The reason you get "48 + Console.ReadKey" is that Console.ReadKey returns the code of the key that was pressed - in this case, the ANSI value of the number character that was pressed.
