How to convert Console.ReadLine() to double in simple calculator ? C# Problem with exception

Question

I used double.Parse and Convert.ToDouble and got the same error

System.FormatException: Input string was not in a correct format

Answer 1

The problem might be your culutral setting. Some countries uses a . others uses a ,

try:

double num2 = double.Parse(Console.ReadLine(), NumberStyles.Any, CultureInfo.InvariantCulture);

or set the separator like:

var culture = (CultureInfo)CultureInfo.CurrentCulture.Clone();
culture.NumberFormat.NumberDecimalSeparator = ".";
double num2 = DateTime.Parse(Console.ReadLine(), culture);
