Regional decimal seperator input

Question

Computers in my country do not accept decimals with a '.' they only accept ','

How do I write a program which would accept 12.5 from the console as a decimal number?

Answer 1

Use CultureInfo. If you are sure that using decimal dot is a standard in your country then use your country's CultureInfo. You can simply check if it is.

// Change kk-KZ to your culture code
decimal dec = decimal.Parse(str, new CultureInfo("kk-KZ")); 

Or you can use InvariantCulture and NumberStyles.Any:

decimal dec = decimal.Parse(str, NumberStyles.Any, CultureInfo.InvariantCulture);

I will implement the second one as I don't know where you are from.
Here it is in an console application and it works for me:

public static void Main()
{
    string str;

    str = Console.ReadLine();

    decimal dec = decimal.Parse(str, NumberStyles.Any, CultureInfo.InvariantCulture);
    double db = double.Parse(str, NumberStyles.Any, CultureInfo.InvariantCulture);

    Console.WriteLine(dec.ToString("F2", CultureInfo.InvariantCulture));
    Console.WriteLine(db.ToString("F2", CultureInfo.InvariantCulture));

    return;
}
